SCIENTIFIC PROGRAMME AND METHODS (by John Toole - November 1994) WHP P06 was carried out from the R/V Knorr in May-July 1992. This quasi-zonal section spanned the subtropical South Pacific Ocean at 30°S 32°30'S. As such, it was defined as the WOCE Heat Flux line for this ocean basin. In addition to the hydrographic section, moored current meter measurements were being maintained in the East Australian Current and the Deep Western Boundary Current east of the Tonga Kermadec Ridge at the time of our cruise. P06 represented the first WHP leg aboard the recently re-engined and jumbo-ized R/V Knorr. Perhaps not unexpectedly, numerous start-up problems were experienced on P06, as problems with the vessel's systems became apparent. Frequent power black-outs were experienced, as well as more subtle instrument problems related to the line voltage. Complicating matters, the break-down of the facility at Easter Island meant that no fuel was available at Easter Island. Extreme conservation requirements dictated reduced ship speed for the first two legs of the program. CTD's and water sample rosettes also presented their share of problems during the expedition. Significant credit must be given to the Knorr's personnel, and the seagoing scientific teams for carrying on with the work despite the difficulties. The expedition was broken into three legs. Leg3, with Harry Bryden as chief scientist (Knorr cruise 138 leg3), departed Valparaiso, Chile on May 2 and occupied 72 stations, 68 of which were along 32°30'S working west from the South American Coast to 109 20 W. On May 24, work was suspended and the Knorr transited north to Easter Island for a personnel change. Leg4 (Mike McCartney, chief scientist) departed Easter Island on May 30 and resumed station work on the 32°30'S line at 109°20'W on June 1st. This, the longest of the three legs, experienced the worst weather and the most problems with instrumentation. Nevertheless, a total of 113 stations were successfully occupied on the leg, extending the section across the Tonga-Kermadec Ridge to 177°32'E. Work was completed on July 4th, whereupon the Knorr transited to Auckland, New Zealand for supplies and another personnel change. The third leg, with John Toole as chief scientist, departed Auckland on July 13 and resumed station work with a reoccupation of the last station taken on Leg4. The ship track was subsequently angled northwest to 30°S and then extended west to the Australian coast at that latitude. The section was completed with a station on the Australian shelf on July 25. Having some extra time at the end of the main section occupation, two repeats of the western most 100 km of the line (that bit across the East Australian Current) were made. The Knorr then headed for port, arriving in Sydney on July 30. Primary responsibility for the basic hydrographic observations fell to the Woods Hole Oceanographic Institution's CTD/Hydrography Group. They were responsible for acquiring temperature, salinity and dissolved oxygen data, and coordinating with other groups analyzing dissolved nutrients and tracer concentrations. This report documents the measurement systems, analysis/processing techniques, uncertainties and residual problems with the reduced data set. Separate sections are included from each of the major groups on the cruise. Specifically, this submission to the WHPO encompasses the CTD observations, water sample salinity, oxygen, nutrients, and underway bathymetry. Underway meteorological measurements have earlier been submitted to the NCAR data center. Access to those measurements is described below. A separate document will be submitted by Kevin Maillet (RSMAS) on the CFC program. During the three-leg expedition, a number of test stations were carried out to assess instrument performance and/or inter-comparability of data. Those are not reported here. In the majority of cases, these test stations were duplicates of stations along the main section line that are reported here, but with different CTD instruments. Thus, technically according to WHP guidelines, they should have been labeled as different casts not different stations. In this group are Stations 73 (CTD No.7) and 74 (CTD No.9), collocated with station 72, 141 (CTD No.9 collocated with station 142), 187 and 189 (CTD No.9, collocated with stations 188 and 190) and 247, (repeat of sta 233 for additional CO2 sampling) (CTD No.9, collocated with station 248). Stations 1, 2 and 3 were made with different CTD instruments at the start of the cruise to assess instrument performance and allow specification of the primary for the cruise. They were not along the main section line and so are not reported here. Thus the P06 line begins in the east with Station 4. Station 112 with CTD 9 experienced significant instrumentation failures making the acquired data of very questionable accuracy. It was deemed unrecoverable during processing. The western most station of the main P06 line was number 246. In addition to the main occupation, two repeat sections were made across the East Australian Current of stations 237- 246. They consist of stations 248-257 and 258-267. Primary attention was paid in the post-cruise calibration of these stations to the CTD salinity data; the CTD oxygen data were not scrutinized to the same degree as the data along the main line. A.4.1. Leg 5 Overview (Toole, chief scientist) R/V Knorr cruise 138 - Leg 5 is the third and final segment of the transpacific WOCE Hydrographic Program section P06. Segments 1 and 2 obtained measurements along latitude 32°30'S between South America and the Tonga-Kermadec Ridge (approximately at the date line). Our segment was planned to extend the measurements to the Australian coast. The selection of 32°30'S for P06 Segments 1 and 2 was dictated by the WOCE deep western boundary current meter array deployed at this latitude east of the Kermadec Ridge; stations were obtained between each current meter mooring of the array. A second WOCE moored array, this one off the Australian coast just poleward of 30°S, was deployed by CSIRO (Australia) investigators to measure the East Australian Current (EAC). Sampling on Segment 3 was designed to survey along this array. Thus, the P06 sampling plan called for a northward deflection of the cruise track from 32°30'S to 32°05'S. This was planned for the longitude range 179 - 176 30'E, within the South Fiji Basin. The sampling plan for P06 called for an average station separation of 30 NM, with tighter spacing where the bathymetry changed rapidly. A total of about 50 stations was envisioned for Segment 3. Casts were to be done using the Scripps ODF 36-position x 10-liter rosette system and CTD instrumentation from the WHOI Group. Water samples were to be spaced no greater than 200 m in the vertical. The WHOI Hydrographic Group was responsible for analyzing water samples for salinity and dissolved oxygen; sampling for tritium and helium was planned for subsequent shoreside analysis in the WHOI facility. Both groups were to utilize their self-contained portable laboratories. The OSU group was tasked with analyzing water samples for dissolved nutrient concentration. These activities were planned for the climate-controlled laboratory aboard the Knorr. The P06 CFC sampling was divided up by several U.S. investigators working in collaboration. Collection of samples for C-14 analysis were planned for the Princeton and Australian groups. In addition, a CO2 program was planned in association with JGOFS. M. Kosro undertook responsibility for underway ocean velocity measurements using an Acoustic Doppler Current Profiler (ADCP). Complementing these observations were a number of meteorological and ocean surface measurements planned from the vessel. Finally, deployment of WOCE ALACE floats along the cruise track was scheduled roughly every 2.5 degrees of longitude. If additional time was available after the completion of the primary sampling line, repeated sampling of the EAC was planned to better define the boundary current transport at the time of the section. What was envisioned were repeats of the last 100-150 km of the P06 section in combination with a series of ADCP transects. CRUISE PERSONNEL The major groups involved in WHP observation program were the CTD/Hydrography/nutrient team, the CFC group, a transient tracer contingent, and an underway sampling group. The leg had a true international feel as the science party included folks from CSIRO Australia, led by my co-investigator John Church, and a NZOI, New Zealand scientist. As in the case of the first two legs, a CO2 program was aboard under the direction of the Brookhaven National Laboratory (BNL), Upton, NY. The CO2 group consisted of two BNL employees (K. M. Johnson and V. Coles) and an Australian scientist, B. Tilbrook, of CSIRO. CRUISE NARRATIVE Staging for Kn 138-5 was minimal as all equipment was in use on the preceding two legs. The Knorr arrived in Auckland on July 6, one day ahead of schedule. On the 7th, a small group met to debrief the previous leg participants and clarify cruise-specific procedures. Cruise Leg 4 had achieved its planned sampling to 177°30'E; no extra station work was therefore required of Leg 5. One of the WHOI salinometers had developed an intermittent fault during Leg 4; a back-up instrument was air shipped to Auckland as replacement. As well, the phosphate channel of the nutrient autoanalyzer failed on the preceding leg (and its back-up). Spare parts for this instrument also met the ship in Auckland. Poor quality ship electrical power was implicated in both of these failures, but not conclusively demonstrated. In any event, a harmonic filter, a replacement for the original unit which had failed on Leg 1 (?), was delivered to the Knorr in Auckland and installed on the "clean power" supply. Also, additional components were fitted to the controller of the Markey winch while in port. This unit was serviceable on the preceding leg, but because of poor slow-speed control (resulting in rough recoveries of the CTD package back on deck) was not employed regularly. The winch used as primary on the preceding leg (the Almon- Johnson) required manual application of a brake when stopping to acquire water samples. It was my understanding that repair components for the Almon-Johnson brake were also to be installed in Auckland, but that turned out not to be the case. In mid-week, when most of the scientific party had yet to arrive, it was discovered that the software licenses for the WHOI CTD Group data acquisition and processing computers had expired. Renewal is usually carried out under contract with WHOI's computer support facility. In this case, the stand-alone operating systems on the sea-going computers had been generated just prior to updating the WHOI-wide licenses. In this state, data acquisition software would not work, and the systems were next to useless. Thanks to long hours by Ellyn Montgomery (the CTD Data Manager for Leg 5) and Tom Bolmer back at WHOI, the problem was identified and solved, leaving the chief scientist slightly frazzled but in business. At 0800 on our scheduled departure date of July 13 the Knorr moved to the fuel pier and commenced bunkering. At 1600 we departed Auckland and headed north to our first station. The ship track for Kn 138 Legs 3,4,5 is presented in figure 1. The transit out from New Zealand was a bit rough (particularly for just starting out) but not bad. We held a cruise meeting with the science party on the 14th while in transit, and assigned watches (Attachment A). We arrived at the first work site (31°5'S 177°32'E) on July 14 at 2000Z, where Leg 4 investigators completed their work with lowerings of the primary (Sta. 188) and principle back-up (Sta. 189) CTD instruments. We began by doing the same; Sta. 189 was with the back-up (CTD #9), Sta 190 with the primary (CTD #10.) Potential temperature-salinity curves for the deep water from Stas. 187- 190 show both primary and back-up CTDs did not change calibration during the Auckland port stop. Furthermore, examination of the deep temperature records from CTD #10 and the secondary temperature sensor integrated into the instrument (a stand- alone platinum thermometer) showed the temperature calibration of instrument 10 remained stable during the repair work conduced during Leg 4. (The temperature difference between the two sensors changed less than 0.5°C, essentially un-measurable.) Station work then proceeded west as planned, pretty much uneventfully. At the request of ship's personnel, we moved operations to the Markey winch. With its repaired controller, the winch performed acceptably. On Sta. 201, the CTD package was inadvertently lowered into the bottom at full lowering speed (60 m/min). The shock broke the mounting brackets holding the CTD in the underwater package, but the unit was recovered. On Sta. 213 the underwater package struck the ship's bulwark on deployment rather severely. Comparison of the two temperature records showed no change in temperature difference resulting from these impacts. As it is unlikely that both sensors would shift the same amount, we conclude the shock of hitting the bottom and the ship did not measurably change the temperature calibration. A small shift of the conductivity channel did result from the bottom contact, however (but is correctable using the salinity water samples). Much of Leg 5 crossed shallow bathymetric features. Over these features, water sampling was reduced to 24 or at times fewer bottles (but still retaining minimum 200 m vertical resolution). Watch standing duties were much reduced at these times as the ODF rosette did not have to be disassembled and reassembled at each cast. On Sta. 215 a bearing failed in one of the turning sheeves used to fairlead the wire overboard from the Markey winch. The cast was recovered successfully and operations shifted back over to the Almon Johnson winch (requiring a second hand to operate the brake.) Ship's personnel were unable to locate a replacement bearing, effectively putting the Markey winch out of operation after about 30 lowerings. The station work was successfully completed using the Almon-Johnson winch with manual braking. In general, both winches, when operable, performed well: level winding properly, raising and lowering the CTD/rosette as fast as the package size allowed. ALACE deployments occurred at regular intervals during the cruise. Peter Landry, (CTD Technician for the leg) took responsibility for assembling and checking out the units. Deployments were uniformly uneventful. At longitude 159°E the cruise track was diverted south 15 miles to avoid the Elizabeth Reef. Sta. 226, the only site off the 30°5'S line west of 176°E was taken at 30°20'S 159°5'E. At longitude 156°30'E, two CTD casts were made (denoted Stas. 233,234). The second cast provided water for an inter-comparison of small volume C-14 facilities (U.S. and Australia). Bronte Tilbrook is the point of contact for this study. Several in the scientific party and crew took advantage of the good weather and time between casts (when samples were being drawn) for a quick swim call. Approaching the Australian coast, station spacing was reduced to as little as 5 NM crossing the East Australian Current. The bottom profile approaching the continental shelf at latitude 30°5'S is quite complicated, with very steep sections. Station positions were adjusted in an attempt to sample between each current mooring of the EAC array, while avoiding large cast to cast changes in bottom depth. Turn-around time between stations was lengthened at this time to allow those running water samples aboard ship to keep up. Sta. 246, marking the end of the P06 section, was occupied on July 25 in 90 m of water on the Australian shelf. Upon completion of the primary section, the ship reversed course and returned to position 30°5'S 155°E, site of Sta. 237. The run east provided a synoptic map of the EAC current field using the ship mounted ADCP system. Having the time, we proceeded to make two repeat sections across the EAC using a small (24 position x 1.2 liter) rosette system. Installation of the CTD in this rosette necessitated a 90° rotation of the sensor head on the instrument. Cast 247 was conducted with CTD instrument 9 in the large rosette. Then, we rotated the head to its normal vertical position, and took Sta. 248 in the same location with the small rosette. This was done to document any sensor calibration change resulting from the head rotation. Work then proceeded west, reoccupying stations made on the primary crossing. On Sta. 252 the CTD package again hit the bottom. The cable was badly kinked within 30 m of the CTD as a result, requiring us to re-terminate. Stations 248--257 constitute the first repeat section, Stas. 258--267 the second. After completing the repeat EAC sections, the ship headed southeast to make an ADCP section at latitude 32°15'S. The section ran from 155°E into the coast (153 xxE). Then we transited south in deep water while performing tests of the ADCP instrumentation while the scientific party began packing equipment. We picked up the Sydney pilot early on July 30, and docked shortly thereafter. Overall the leg was very successful and generally uneventful. Unlike the previous legs, weather was moderate much of the time keeping spirits high. Again in contrast to the previous legs, we did not experience significant difficulties with electrical power in the labs. Some mix of the crew's ongoing upgrade of ship's systems, installation of the harmonic filter, and the science team's increased ability to cope with less than perfect power is probably responsible for the improvement. Following Marshall Swartz's lead from Leg 3, an informal study of electrical power was begun on Leg 5, but this was terminated when it was deemed it too intrusive to ship operations. As sea conditions were quite moderate, we did not experience excessive stern slamming as on the earlier legs. When it did occur however, the feeling was quite disconcerting, both for the amplitude of the flexing and its duration. However, at no time during Leg 5 were operations affected by stern slamming. Having two working winch systems proved very valuable. Wire re-terminations could be done with no loss of work time. As expected, electronic communication via the ATS satellite was not possible for most of the leg because we were too far west. Although effort was made, we were unable to make the system function through Inmarsat. Communications were limited to Telex traffic and the occasional FAX. Finally, and perhaps most importantly, we found the crew and officers to be highly knowledgeable, helpful and friendly. Their efforts to bring the Knorr back to fully operational status are to be commended. I also found everyone in the science party to be good shipmates, and fun to work with. SUMMARY OF OBSERVATIONS Table 1 contains a list of hydrographic stations which make up the P06 section. For completeness, the listing includes all of the stations which make up the P06 line. A total of 79 CTD stations were obtained on Kn 138 Leg 5, 56 contributing to the one-time P06 section, 20 making up the repeated surveys of the EAC, one inter-comparison lowering and 2 test lowerings. Approximately 1400 water samples were obtained along the one-time section on Leg 5 (7700 on the full section, fig 2). All samples were analyzed for salinity, dissolved oxygen and nutrient (silica, phosphate, nitrate, and nitrite) concentrations. The measurements of the dissolved chlorofluorocarbons (CFCs) along this section were carried out by Dr. Mark Warner and Matthew Trunnell, both from the University of Washington, using the SIO analytical system. This system had been used on the previous two expeditions, so all of the analytical problems had been eliminated. Approximately 690 samples from 38 stations were analyzed for F-11 and F-12. Approximately 30 of these were duplicate samples from the same 10- liter bottle. No CFC samples were drawn after station 247 due to the use of the smaller rosette package with 1.2-liter bottles due to both the lack of sufficient amounts of water and the higher contamination levels in these bottles. These preliminary data have been included in the cruise hydrographic data files (.sea files) without many of the necessary corrections and elimination of questionable data points. The CFC concentrations in the overlying air were also measured at least once per day during the expedition. Dr. Warner also continued to run the underway system of Dr. Ray Weiss. This system measures the partial pressures of carbon dioxide, nitrous oxide, and methane in surface water and the atmosphere. These measurements are each made twice per hour. Dr. Bronte Tilbrook of CSIRO operated a similar system for intercalibration purposes on this expedition. Samples were extracted at 19 stations for shoreside determination of helium and tritium concentrations, and 12 stations for C-14, Table 2. Continuous logs of underway meteorology (via the IMET system) and surface ocean properties were obtained, as well as bathymetric data every 5 minutes while underway between stations. A total of 11 ALACE floats were deployed on the leg, Table 3. Samples were collected by the CO2 group from 22 stations at approximately 2 degree spacing. Eighteen of these stations were sampled concurrently with freons and other tracers. Some 549 samples were analyzed for total dissolved carbon dioxide (TCO2), and of these 256 were also analyzed for the partial pressure of CO2 (pCO2). The TCO2 analyses were made on an automated instrument (SOMMA) designed by K. M. Johnson with coulometric detection, while the pCO2 analyses were made using a static equilibration technique under development at BNL utilizing a gas chromatograph for detection of CO2 after conversion to CH4. In addition, the SOMMA instrument was equipped with a Seabird SBE-4 conductance cell for the determination of salinity. The precision of the TCO2 determination (estimated from the average difference between duplicate bottles collected from the same Niskin bottle (n = 45 pairs) is 0.60 µmol/kg. Using an average TCO2 concentration of 2150 µmol/kg on this leg yields a precision of 0.028 %. Accuracy is estimated from the analyses of two certified reference standards (CRM) having values of 1960.67 and 2188.77 µmol/kg, respectively. Our mean result for these CRM on leg 3 are 1959.21 (n=15) and 2187.17 (n=23), respectively. In aggregate, the BNL groups analyzed more than 3000 samples for TCARBN, and nearly 1000 samples for pCO2 during the P06 section. The TCO2 data appears to be of high quality, and TCO2 will be contoured for the P06 section. The quality of the pCO2 data is not yet known because phase volume corrections are still to be made. Also encouraging is the preliminary finding that our salinity determinations agree with the salinometer result to better than 0.01 ppt. ADCP data was collected throughout the cruise, along with navigation data from the ship's Magnavox GPS 200 receiver and heading from the ship's gyrocompass. In addition, independent heading measurements were collected using an Ashtech 3DF GPS receiver, which also provided 1 Hz measurements of pitch and roll. Data files containing the preliminary hydrographic observations were shared among the cruise participants at the completion of the cruise.

UNDERWAY MEASUREMENTS B.1. NAVIGATION AND BATHYMETRY (John Toole) Manual logging of ocean depth was conducted on all 3 legs of P06. This work utilized the 12 kHz sounding system installed on the Knorr. Following WHPO guidelines, depths were noted every 10 minutes along track between stations. Position data for each depth measurement was extracted from the GPS fix record taken by the shipboard ADCP system (M. Kosro, lead scientist). Three ASCII files are submitted: LEG3.FNL, LEG4.FNL, LEG5.FNL formatted with one line per measurement of: time, latitude, longitude, depth. Time is in decimal day in 1992; the position data are in decimal degrees (negative being south and west respectively). The depth data in meters are uncorrected for speed of sound. Time gaps in the record correspond to periods on station when the ship's pinger was turned off to facilitate tracking the CTD package. B.2. ACOUSTIC DOPPLER CURRENT PROFILER (ADCP) (Mike Kosro) This section not available as of December 7, 1994 B.3. THERMOSALINOGRAPH AND UNDERWAY DISSOLVED GASSES (Charles Corry) A Falmouth Scientific Instruments (FSI) thermosalinograph (TSG) was mounted on the bow of the Knorr approximately 3 m below the surface and operated on all legs except the latter part of Leg4, where corrosion of the anodized aluminum housing rendered it inoperable. The instrument was replaced in Auckland and operated satisfactorily throughout Leg5. Comparisons between the surface water samples and the thermosalinograph were done on Leg3 and the results are given in Table 5.

An underway fluorometer was operated on Legs 3 and 4 but failed before the end of Leg 4. John Marra, LDEO, was the principal investigator for that measurement. A number of underway measurements of the atmospheric chemistry were made by Ray Weiss group. B.4. EXPENDABLE BATHYTHERMOGRAPH AND SALINITY MEASUREMENTS No XBT or XCTD casts were done on any leg of this cruise. B.5. METEOROLOGICAL OBSERVATIONS (Margaret Cook) Data from the IMET system aboard R/V Knorr was reduced by Ken Prada (WHOI) and submitted to NCAR. The P06 data in NetCDF format are available via the network from Steve Worley at NCAR. His network address for email is worley@ncar.ncar.edu He can also be reached by telephone at (303) 497-1248. To access these data, Steve Worley should be contacted at NCAR. He will set up an anonymous FTP for you. The address of the machine we extracted data from was ncardata.ucar.edu. He will enable you to receive UNIX TAR files across the network. Most of these contain data files. There is a file, imet_asc.tar, which contains the full software package for reading the NetCDF files. Program imet_asc is used to access the binary NetCDF files and output ascii files for subsequent analysis. There are a few things we learned about this data which will be of interest to whomever is using it. 1. Wind direction is logged in oceanographic rather than meteorological terms. That is, where the wind is going, rather than where it is coming from. 2. Corrections were supposedly being made automatically to the data based upon a compass installed in the wind sensor. Unfortunately, the compass was not always working correctly. The theory is that when it was not working, no corrections were made. We understand that during P06 the compass was probably disconnected and so the data does need to be corrected for ship's speed and direction. 3. The files contained in the TAR files are not always chronological. Many files contain two or more nonconsecutive time periods, and one time period may be split between two or more nonsequential files. There are also many time periods which seem to be missing altogether. ____________________________________________________________________________________________ ____________________________________________________________________________________________ C. HYDROGRAPHIC MEASUREMENTS C.1. GENERAL INFORMATION The Woods Hole Oceanographic Institution's CTD/Hydrography Group was responsible for the basic hydrography on the P06 cruise. We employed A 36-bottle-position underwater frame and 10-litre sample bottles designed and constructed by the Ocean Data Facility at the Scripps Institution of Oceanography. Modified MkIII Conductivity-Temperature- Depth (CTD) instruments mounted on the frame were supplied by the WHOI Group, as were the data acquisition and processing computer systems. Three CTD instruments (WHOI ID's #7, 9 and 10) were available during the cruise. Instrument #10 was used on the bulk of the stations; #9 was pressed into service briefly during the middle leg when #10 suffered an electronic failure. Details of which instrument was used when are given in Water sample nutrient data The following was excerpted from the at-sea log kept by the CTD data processor on each leg (Carol MacMurray: Legs 3, 4; Ellyn Montgomery: Leg 5). The log details the major difficulties experienced on P06. In general, operations on stations not discussed below went more-or-less normally. CTD 10 was the primary instrument on the cruise, No.9 was called into service for some 10 stations during leg 3 when No. 10 failed. CTD No. 9 also failed on that leg, but by that time CTD No. 10 had been repaired. Details of which CTD was used on which stations are given in Table 6. TABLE 6: CTD instrument and station numbers CTD Number Cruise Leg Station Numbers ---------- ---------- ------------------------------------ CTD 10 Leg 3: 1, 4-72 Leg 4: 74, 75, 86-111, 113-140 142-186,1 88 Leg 5: 190-212 CTD 9 Leg 3: 3 Leg 4: 76-85, 112, 141, 187 Leg 5: 189 CTD 7 Leg 3: 2 Leg 4: 73 Leg 5: None CTDs 9 and 10 were equipped with a second temperature channel (using an FSI Ocean Temperature Module). Data from these sensors were used to assess when during the cruise shifts in the primary temperature sensor occurred. CTD No. 10 was also equipped with a pump, designed to make uniform the flow of seawater past the dissolved oxygen sensor. The oxygen pump was used throughout leg3. Careful examination of the Leg3 data after the cruise suggested the pump did not function as well as was hoped (or tested on earlier expeditions). The oxygen current data are quite noisy in the top several hundred meters from Leg3. (Possibly the pump was cavitating on air not bled from the supply tube.) In any event, the final P06 data from Leg3 have quite noisy oxygens in the upper ocean. Users may wish to do some vertical averaging/filtering prior to using these data. The oxygen pump was removed from the system at the start of Leg4 and not used for the rest of the expedition. SHOREBASED PROCESSOR: MicroVAX Data subdirectory: R2D2:1100 dbar (d) fitting for slope using bias from (b), with observations >1100 dbar (a) and (b) gave similar enough slopes and (c) and (d) were similar to both (a) and (b). As a result, we decided use the averaged pre and post cruise laboratory bias and fit throughout the cruise for conductivity slope using the water sample data. We further concluded that the nominal coefficient for conductivity cell distortion under pressure of beta=1.5E-8 gave acceptable results in the deep ocean (where this term has the most noticeable effect). Final fits are tabulated in Appendix F. However, careful examination of the CTD - water sample conductivity data from the thermocline revealed several irregularities e.g., curvature of the CTD-water sample residuals in pressure and temperature. Several non-standard procedures were implemented in order that the final calibrated CTD salinity downcasts were consistent with the water sample salinity data. In addition to altering alpha, the coefficient of thermal expansion of conductivity cell, from its nominal value of -6.5E-6, an empirical correction to the conductivities in the upper third of the ocean was implemented in order that the derived CTD salinity data agreed with the water samples. The correction was, as stated, done to the raw CTD conductivity data, although it may have been equivalently applied to the CTD temperature. The small magnitude of the shift (around 0.002 psu) was such that we could not distinguish. It is suspicious that the empirical correction was needed for CTD stations collected with instrument No. 10 after it had failed on Leg4 and been opened for repair. This hints that it may have been a temperature shift. However, as the error signal was detected in salinity, we decided to alter conductivity. SUMMARY OF NON-STANDARD CORRECTIONS TO CONDUCTIVITY: CTD No.10 Station 1 to 75, 86 to 247 reduced alpha by half in conductivity to increase surface CTD salt by 0.002 psu at 0 db. This was done to straighten out hooked profile of salinity residuals plotted against pressure. Changed alpha for all CTD 10 stations so that alpha was consistent for CTD 10 throughout cruise. Alpha = -3.25E-6 for all CTD 10 stations. Station 86 to 246 added an empirically determined conductivity offset (which was a function of pressure) to the downcast CTD conductivity profile data and the upcast data collected at the time of water bottle tripping. The offset C- off was of the form: C-off = 1.47781E-8 *{P**2} * exp{-[P/500]} The offset was thus zero at the surface, approached zero exponentially at depth and had a maximum effect of 0.002 mmho at 1000 dbars. Station 76 to 85 CTD 9 alpha was increased above the nominal value to reduce surface CTD salt. Alpha set to -16.25E-6. Station 249 to 267 CTD9 the nominal alpha of -6.5E-6 was employed successfully for these data. It is not known why a different value from the earlier station group worked. Given these shaping parameters, conductivity slope factors were derived by regression against the water sample data following standard procedures. Conductivity fits applied to the final CTD data are tabulated in Appendix F. CTD OXYGEN MEASUREMENTS Leg3, stations 4 to 72, CTD 10 used a pump in conjunction with the oxygen sensor. As noted above in C.1 General Information, the data collected with the pump was difficult to process. Specifically, the top 500 meters of oxygen current were very noisy and very difficult to fit. A nonstandard method of fitting the top water (0 to 1000db) and bottom water (1000db to bottom) separately was used. The resulting deep CTD oxygen has a good fit, similar to the following legs. An advantage of using the pump was the station bottoms lacked the typical oxygen tail seen in legs 4 and 5, where the oxygen drifted low due, most likely, to the slowing of the package as it neared the bottom. The pump might have kept the water flow rate past the oxygen sensor constant, thus not artificially lowering the oxygen current. As well there were the usual difficulties processing data from this sensor. See Owens and Millard (1985) for details to the algorithm. QUALITY CONTROL OF 2-DBAR CTD DATA QC SALTS: Salinity spikes on or near sea surface were not uncommon. Guideline for quality marking: If the spike is greater than .2 mark the quality word as bad. For spikes smaller than .2 mark quality word as questionable. Don't mark if spike is substantiated by water samples (see station 55). The spike might not be marked questionable if it looks real such as a small spike to the fresh side, that changes with temperature as well as salinity. Causes: As package enters water it is possible the pressure averaging for the first three dbrs. is incorporating conductivity data from above and below the water surface causing large salt spikes. OXYGENS: Surface spikes, were the norm for the entire cruise. These were neither individually identified nor the quality word labeled. Noisy data in top 500 dbar for all CTD10 stations on Leg3 associated with use of oxygen pump. Leg3 variability on the order of =/-0.2 ml/l. Leg4 and 5 variability on the order of =/-0.05 ml/l. Bottom tails, where oxygen is drifts off low are common in Legs 4 and 5. Likely due to the slowing descent rate of the CTD as it approaches the bottom. The reduced flow past the oxygen sensor results in a lower oxygen current and thus lower oxygen value. D. ACKNOWLEDGEMENTS E. REFERENCES Anonymous. 1985. RFA-300 Rapid Flow Analyzer Operation Manual.

FINAL REPORT FOR AMS 14-C SAMPLES (WOCE P06) (Robert M. Key} July 9, 1996 1.0 GENERAL INFORMATION WOCE P06 was a zonal section consisting of three cruise legs which are treated collectively here. The legs were carried out on R/V Knorr and have the cruise designation 316N138_3, /4 and /5 or P06E, P06C and P06W. Dates, port stops, chief scientists and station numbers are summarized in Table 1. This report covers details of the small volume radio-carbon samples. The reader is referred to cruise documentation provided by the individual chief scientists as the primary source for cruise information. Of 267 stations, 30 were sampled for radiocarbon. Unfortunately, station 3, which was sampled and has had 14-C analysis completed, has yet to be reported in any hydrographic data report. Consequently, that station is omitted from this report. The AMS station locations are shown in Figure 1* and summarized in Table 2. TABLE 1: P06 Leg Summary Leg WOCE ID Chief Sci.

Rotter (P06E) and G. McDonald (P06C & P06W), both from Princeton U. 14-C analyses were performed at the National Ocean Sciences AMS Facility (NOSAMS) at Woods Hole Oceanographic Institution. Salinities and nutrients were analyzed by the WHOI CTD group and the Oregon State Univ. group respectively. R. Key (Princeton) collected the data from the originators, merged the files, assigned quality control flags to the 14-C and submitted the data files to the WOCE office (7/96). Key is PI for these 14-C data. 3.0 RESULTS This 14-C data set and any changes or additions supersedes any prior release. 3.1 HYDROGRAPHY Hydrography from these legs (with the exception noted above) have been submitted to the WOCE office by the chief scientists and described in the final hydrographic reports. 3.2 14-C Most of the delta-14-C values reported here have been distributed in a data report (NOSAMS, 1994, 1995). That report included preliminary hydrographic data and 14-C results which had not been through the WOCE quality control procedures. This report supersedes those data distributions. At this time 649 of 1089 samples have been measured and reported. Replicate measurements have been made on 17 of the water samples. These replicate analyses are tabulated in Table 3. The table shows the mean and standard deviation for each set of replicates. For these few samples, the average standard deviation is 6.8 ‰. This precision estimate is approximately correct for the time frame over which these samples were measured. For a summary of the improvement in precision with time at NOSAMS, see Key, et al. (1996). Note that the errors given in Table 3 and in the final data report include only counting errors, and errors due to blanks and backgrounds. The 5-7 ‰ error obtained for replicate analysis is an estimate of the true error which includes errors due to sample collection, sample degassing, etc. In the final data reported to the WOCE office, the error weighted mean and error weighted standard deviation of the mean are given for replicate analyses.

Only first value reported in final data set 4.0 QUALITY CONTROL FLAG ASSIGNMENT Quality flag values were assigned to all 14-C measurements using the code defined in Table 0.2 of WHP Office Report WHPO 91-1 Rev. 2 section 4.5.2. Measurement flags values of 2, 3, 4, 6 and 9 have been assigned to date. Approximately 400 samples remain to be measured. With a few exceptions, these samples will be completed. Currently, the unmeasured samples are incorrectly coded with a flag value of 9 (no sample collected) rather than 1 (sample collected) or 5 (no result reported). The choice between values 2 (good), 3 (questionable) or 4 (bad) is involves some interpretation. There is very little overlap between this data set and any existing 14-C data, so that type of comparison was difficult. In general the lack of other data for comparison led to a more lenient grading on the 14-C data. When using this data set for scientific application, any 14-C datum which is flagged with a "3" should be carefully considered. My subjective opinion is that any datum flagged "4" should be disregarded. When flagging 14-C data, the measurement error was taken into consideration. That is, approximately one-third of the 14-C measurements are expected to deviate from the true value by more than the measurement precision. No measured values have been removed from this data set. Table 4 summarizes the quality control flags assigned thus far to this data set. For a detailed description of the flagging procedure see Key, et al. (1996). As more of the Pacific data set becomes available, it is possible that some of these flag values may be modified. Any additional data received for this leg will be reported to the WOCE office as they become available. TABLE 4: Summary of Assigned Quality Control Flags Flag Number ---- ------ 2 646 3 10 4 6 6 17 5.0 DATA SUMMARY (Figures available in PDF version) Figures 2-5* summarize the AMS 14-C data collected on this leg. Only delta- 14-C measurements with a quality flag value of 2 or 6 are included in each figure. Figure 2* shows the delta-14-C values with 2-sigma error bars plotted as a function of pressure. The data density in this figure is representative for these legs: approximately 3 times as many samples were collected in the thermocline as in deep and bottom waters. The mid-depth delta-14-C minimum at approximately 2500 meters is clearly evident. Figure 3* shows the delta-14-C values plotted against silicate. The straight line shown in the figure is the least squares regression relationship derived by Broecker et al. (1995) based on the GEOSECS global data set. According to their analysis, this line (delta-14-C= -70-Si) represents the relationship between naturally occurring radiocarbon and silicate for most of the ocean. They interpret deviations in delta-14-C above this line to be due to input of bomb- produced radiocarbon. Clearly, this relationship is not ideal for the P06 data set. The data points having silicate values greater than or equal to 60 µmol/kg almost certainly have no bomb-radiocarbon component and should therefore lie on, rather than below, the line as seen in Figure 3*. For these data the slope of the line needs to be steeper or/and the intercept needs to be lower. Also strongly diverging from the trend are one group of points having silicate concentrations between 105 - 125 µmol/kg. These data are from the near-bottom water at stations between approximately 160°W and 180°W; that is, some form of northward flowing circumpolar bottom water. For silicate values greater than approximately 40 µmol/kg the shape of the delta-14-C vs. Si trend is better described as a backward "J" which is rotated counter-clockwise. Figure 2*: AMS delta-14-C results for P06 stations shown with 2-sigma error bars. Only those measurements having a quality control flag value of 2 are plotted. Essentially all of the deep and bottom waters in the South Pacific examined during WOCE shown this same shape. The shape is, of course due to the fact that the delta-14-C and Si extreme fall at different depths and have similar, but different ratios on either side of the extrema. If one follows Broecker's argument, but modifies it so that only data which have no tritium and are above the shallower of the Si and delta- 14-C extrema, one should still be able to get an estimate of the pre- bomb radiocarbon. To that end (and erring on the safe side), a least squares fit of the data from samples between 1 and 2 km depth (n=141; R^2 =.91) gives an intercept of -63±3 and an intercept value of - 1.34±.03 both of which are significantly different than the -70, -1 which Broecker calculated for the GEOSECS global data set. Figure 4* is an objectively contoured section (LeTraon, 1990) of the delta-14-C distribution for the upper 1.5 kilometer of the water column The most prominent features of this section are the general upward tilt of the isopleths eastward of 120°W and the sharp upturn of the isopleths in the 250-750 meter depth range just off South America. This second trait is probably due to upwelling and is reflected in the low surface concentrations on the east end of the section. At this point, the upward slope of the deeper isopleths is interpreted as a shallow indication of the deeper southward flow at the eastern side of the section. Figure 5* shows the entire section contoured. Both Figure 4* and Figure 5* were gridded using the method of LeTraon (1990), however, the horizontal correlation length scale used for Figure 5* was 2.5 times that used for Figure 4* to compensate for the sparser sampling in the deep and bottom water (i.e., the full water column section was significantly smoothed relative to the first). The delta-14-C minimum centered around 2500m depth is definitely not continuous across the section. The break in the minimum at 260° (100°W) is reflected in other tracers and is indicative of northward flow along the east side of the ridge. Figure 3*: delta-14-C as a function of silicate for P06 AMS samples. The straight line shows the relationship proposed by Broecker, et al., 1995 (delta-14-C = -70-Si with radiocarbon in ‰ and silicate in µmol/kg). Figure 4*: delta-14-C concentration in the upper kilometer of TUNES leg 3; WOCE line P06) along 155°W. Gridding done using the method of Letraon (1990); all samples measured using the AMS technique (Key, 1996a,b; Key, et al., 1996). For most of the section the maximum concentration is found below the surface. Figure 5*: delta-14-C contour of WOCE section P06 at approximately 32°S. Longitudes are east of Greenich. Objective gridding done using the LeTraon (1990) method with a relative long horizontal correlation length scale. The samples in the near bottom water mass centered on 190° and having relatively low delta-14-C are those which fall above the general deep water trend in Figure 3*. The minimum layer has 2 cores centered on 210° and 280°. Both are interpreted as southward flow of "old" water from farther north. The core which is against South America was completely missed by GEOSECS due to lack of coverage during that program. At this point it is not clear whether the eastern core represents a return flow from the North Pacific or simply return flow of waters which have remained in the South Pacific. 5.1 REFERENCES AND SUPPORTING DOCUMENTATION Key, R.M., WOCE radiocarbon program reports progress, WOCE Notes, 8(1),12-17, 1996 Key, R.M., WOCE Pacific Ocean radiocarbon program, Radiocarbon, submitted, 1996.

WHPO SUMMARY Several data files are associated with this report. They are the p6c.sum/ p6w.sum/p6e.sum, p6c.hyd/p6w.hyd/p6e.hyd, p6.csl and *.wct files. The p6c.sum/ p6w.sum/p6e.sum files contains a summary of the location, time, type of parameters sampled, and other pertinent information regarding each hydrographic station. The p6c.hyd/p6w.hyd/p6e.hyd file contains the bottle data. The *.wct files are the ctd data for each station. The *.wct files are zipped into one file called p6awct.zip/p6bwct.zip/p6cwct.zip /p6dwct.zip/p6ewct.zip . The p6.csl file is a listing of ctd and calculated values at standard levels. The following is a description of how the standard levels and calculated values were derived for the p6.csl file: Salinity, Temperature and Pressure: These three values were smoothed using the following binomial filter- t(j) = 0.25ti(j-1) + 0.5ti(j) + 0.25ti(j+1) j=2....N-1 When a pressure level is represented in the *.csl file that is not contained within the ctd values, the value was linearly interpolated to the desired level after applying the binomial filtering. Sigma-theta(SIG-TH:KG/M3), Sigma-2 (SIG-2: KG/M3), and Sigma-4(SIG-4: KG/M3): These values are calculated using the practical salinity scale (PSS-78) and the international equation of state for seawater (EOS-80) as described in the UNESCO publication 44 at reference pressures of the surface for SIG-TH; 2000 dbars for Sigma-2; and 4000 dbars for Sigma-4. Gradient Potential Temperature (GRD-PT: C/DB 10-3) is calculated as the least squares slope between two levels, where the standard level is the center of the interval. The interval being the smallest of the two differences between the standard level and the two closest values. The slope is first determined using CTD temperature and then the adiabatic lapse rate is subtracted to obtain the gradient potential temperature. Equations and Fortran routines are described in UNESCO publication 44. Gradient Salinity (GRD-S: 1/DB 10-3) is calculated as the least squares slope between two levels, where the standard level is the center of the standard level and the two closes values. Equations and Fortran routines are described in UNESCO publication 44. Potential Vorticity (POT-V: 1/ms 10-11) is calculated as the vertical component ignoring contributions due to relative vorticity, i.e. pv=fN2/g, where f is the coriolius parameter, N is the buoyancy frequency (data expressed as radius/sec), and g is the local acceleration of gravity. Buoyancy Frequency (B-V: cph) is calculated using the adiabatic leveling method, Fofonoff (1985) and Millard, Owens and Fofonoff (1990). Equations and Fortran routines are described in UNESCO publication 44. Potential Energy (PE: J/M2: 10-5) and Dynamic Height (DYN-HT: M) are calculated by integrating from 0 to the level of interest. A constant value of specific volume anomaly is assumed. equations and Fortran routines are described in UNESCO publication, Processing of Oceanographic station data. Neutral Density (GAMMA-N: KG/M3) is calculated with the program GAMMA-N (Jackett and McDougall) version 1.3 Nov. 94. ____________________________________________________________________________________________ ____________________________________________________________________________________________ G. DATA QUALITY EVALUATION G.1. DQE OF WOCE P06C HYDROGRAPHIC DATA (A. Mantyla) WOCE P06C is the second leg of three done along about 32S in the South Pacific. The cruise crossed the Southwest Pacific Basins occupying stations from the East Pacific Rise ridgecrest to the Kermadec Islands. Comparisons with nearby high resolution stations from GEOSECS, TUNES and JUNO were reasonably good. Overall, this cruise will be a very nice addition to the Pacific deep data set array. However, there is room for some improvement. Many of the problem areas noted on the P06E leg persisted into this one (see general comments from the P06E DQE report for more detailed remarks). Rosette trip errors were less frequent on this leg, but sampling errors appeared to happen fairly often. Much of the oxygen or salinity data that was flagged as questionable appeared to be samples that were drawn a depth or two off (according to the CTD trace). Those mostly were not rosette trip errors because they occurred in isolated parameters, rather than in all of the samples listed for a specific bottle. A couple of examples are mentioned below, but most have been properly flagged as doubtful data. The nutrient data set suffered by the loss of the phosphate for the last 17 stations. Given a choice, I would have preferred to have lost the nitrite channel. There were a number of unintended double trips, as shown by the wider than normal depth spacing adjacent to the double trips and by the lack of actual CTDO data for the second data listing (ditto marks could have been used). The double trips are fairly obvious and are easy to sort out, but the mis-trips often start at a bottle or two earlier than the obvious pair. I've pointed out some possible cases below that need to be resolved. Those mis-trips would be easier to determine if the CTD information at each intended trip depth were retained in the .sea files, it would also improve the profiles if some data were listed for the depth gaps. The .sum files were more complete on this leg and I didn't see any obvious goofs. However, they need to have position data added for the down and up times, if for no other reason than to show how meaningless the second decimal place is. Bottom soundings are also needed, preferably for the cast down time. COMMENTS ON SPECIFIC STATIONS: Stations 73 and 74: Data not provided, stations apparently a re-occupation of station 72 from the previous leg. Might have been useful to assess measurement consistency between the two legs. Station 79, 1964db: Salinity sample apparently not drawn. It is important to draw salts from all rosette bottles, as salinity compared to the CTD is the most sensitive verification available on the correct tripping of the rosette bottles. Oxygen samples can help, but at this depth, the CTD O2 value was flagged doubtful. Although the other water sample data appears to be ok, there is no actual verification of that assumption. Station 80, btl. 24: Oxygen close to 1.00 ml/l too high. Could it be a typo or transposition of the first 2 figures? Would be ok if so, otherwise flag it questionable. Station 81, btls. 7 and 8: From comparison with the adjacent station profiles, the nutrient samples appear to have been reversed. Most obvious is silicate, phosphate and nitrate gradient is small and there- fore inconclusive. Only bottle 7 flagged doubtful, but bottle 8 should be also. Station 89, btl. 20: A good example of an obvious leaker where the oxygen appears to be ok, compared to the CTD O2 profile (offset to the adjacent bottle). However, the mean of the overlaying O2 samples happens to be essentially the same as the O2 at this level, 5.22 vs. 5.23 ml/., about the value expected. The O2 should be flagged doubtful also. This station is only about 2300m deep in a region uncharted by GEBCO, but expected to be generally deeper. The unexpected bathymetry could have odd effects on the water above, as suggested by the wavy temperature profile and bumpy O2 and silica profiles. Four of the silicates were flagged doubtful, but unless there is some analytical reason for doing so, I would prefer to accept them as ok. Station 90, btls. 35 and 36: The two surface salinity samples are obviously listed in reverse order, most likely due to a sample collection error. They are unstable as listed, and the CTD values are correct. An increase in salinity in the top 2 depths is required to balance the temperature inversion. Unless a reason can be found to reverse the bottle salts, I recommend calling the CTD salts ok, and the bottle salts doubtful. Should have a little more faith in the CTD data. Several other salts on this station seem to be poorly collected, and the O2's at 1420 and 1520db could be reversed, but can't be sure. Deeper one flagged. Station 95: Obvious trip problems (and possible sampling errors). As indicated by bottle 1 listed between 24 and 25; 3 samples listed at 1880db; and 4 depth gaps: near 800, 1420, 1800, and 2290db. The salinity data appear to confirm the present trip levels, but the oxygen and silicate data do not confirm 3 trips at 1880db. Therefore the most likely scenario suggests that bottle 8 and 9 salts were collected from bottle 7; the O2 and nutrient data would match the adjacent station profiles if samples 8-13 were moved up one level, including the missing depths at about 1800 and 1420 db also. Finally, the O2's at bottle 14 and 15 appear to belong one depth deeper. Considering all of the uncertainty above, I have flagged the O2's for bottles 8-15 and all of the nutrients for bottles 8-13 questionable. Station 97, btl. 29: Looks like a typo on the bottle salt, should be 35., not 34. CTD salt was flagged questionable, but both are OK if typo is corrected. If not, accept CTD salt and flag bottle salt as uncertain (or even "bad"). The wide spread in the oxygen data for the six surface trips and the six at 2400db indicate some sort of analytical problem. It's not likely a sampling error, because it is hard to mess up near-surface samples that are close to full saturation. Could be a pickling problem though. Oxygens in general this cruise are not as sharp as they could be. Station 101, btl. 22 at 90m: O2 and salt unlikely at this depth, but would be ok at 60m where only ctd data listed, no water sample data. If left as is, should flag nutrients doubtful also. Station 104, btls. 10 and 11: Both salts high where listed, would be ok one depth down. Other data ok as listed, so not mis-trips. Most likely sample drawing errors. Station 113, btl. 19: All data unlikely at second trip at 307db, but would be ok at unlisted depth of about 250db (where bottle 19 was tripped on the last station). Suggest examine original records to see if 250db was a planned sampling depth. If so, list the data there as ok. Station 143, btl. 8: O2 clearly poor where listed, but would be ok at the unlisted depth between 3762 and 4172db; as would all of the other water sample parameters. If moved, accept data as ok. Station 145, btl. 13: Data questionable at listed pressure, would be ok if moved up one depth. Bottle 13 and 14 double tripped on stations 142 and 147, most likely here also. Station 147, btl. 8: Data flagged doubtful, but would be ok if listed at the unlisted pressure of about 4035db. Probably was start of mis-trip that led to two trips at 3831db. Station 148, btls. 11 and 12: Salt, O2, and silica all indicate bottle tripped one depth deeper. If moved, accept data as ok. Station 149, btl. 13: Data unlikely at this depth, would be ok listed one depth shallower. Looks like another 13 and 14 double-trip. ____________________________________________________________________________________________ ____________________________________________________________________________________________ G.2. DQE OF WOCE P06E HYDROGRAPHIC DATA (A. Mantyla) 27 February 1994 The three legs of WOCE line P06 (E, C, and W) at about 32S in the Pacific, will be a very valuable data set to help fill in the most barren strip of Marsden Squares in the Pacific. The P06 data is generally quite good, but there are a couple of areas that could stand improvement (see below). The PI's have done a thorough job in sorting out rosette-trip problems, but there may be a few more that might be resolved upon re-examination, tabulated below. The data originators probably went overboard in flagging slightly anomalous data points as "bad" data, while the "questionable" data code might have been more appropriate. I've softened or changed some of those flags, but for the most part, the originators codes have been left as is. There were a number of instances where "leaky" bottle were identified to have bad water samples by the salinity check sample, but only the salt and nutrients were flagged, while the oxygen was accepted as ok because it fortuitously appeared to fit in the profile. In the case of verified leakers, all water samples should be flagged doubtful. The oxygen precision in general, while better than many historical data sets was not up to WOCE expectations. The poor precision was seen in the duplicate trip data, mixed layer data, and numerous "bumps" in the deep profiles that were not supported by the CTD O2 data. Although some of the errors were likely due to sampling errors, the rest must be due to the specific analytical techniques used on the cruise. As an example of the excellent precision achieved elsewhere, the CalCOFI cruises, using the Carpenter whole bottle titration method, routinely report mixed layer oxygens that differ by no more than 0.01 ml/l. P06 mixed layer oxygens commonly had a spread of several times that value. I would urge that the analysts seriously reconsider their methodology and give the Carpenter system a try. Salinity results also were not as sharp as WOCE expects, but in this case, I believe the source of the problem lies in the sample drawing stage, rather than in the analyses. According to the cruise report, salinity bottles were only rinsed twice, while nutrients, a part per hundred number, were given 3 rinses. Two salinity rinses is ok if the historical salinity precision of .003 to .005 is the goal, but 3 rinses are a must to reach the WOCE goal of .001. Comparisons with nearby JUNO stations show that the desired WOCE targets are possible, the deep O2 and salt profiles are distinctly smoother (like the CTD profiles on both cruises) on JUNO. That doesn't mean that the P06 data is bad, just that it is possible to do a little better. My impression was that the bumpiest profiles were from stations that started within a few hours of midnight, GMT. The nutrient data looked quiet good, in spite of noticeable offsets from crossing WOCE lines, particularly in the silicate data. I think the cruise to cruise nutrient differences are an indication that the current nutrient methodology is not yet up to WOCE expectations, but both cruise results are as good as any that I've seen. The nutrient data appear to have been evaluated independently from the other data. Some nutrient bumps were flagged doubtful, but had supporting consistent oxygen inflections that were in turn verified by the CTD O2 probe, confirming that the nutrient anomalies were probably real. A few flags have been changed on that basis, but for the most part, I've gone along with the original flags. The ".sum" files are incomplete and should be finished. This format is not very popular to outside groups; coming from the source at WHOI, one would expect to see a model example of how it should be done! Only the cast start time positions are tabulated. The WOCE guidelines expect a position for the cast down time (which is when the water sampling begins) and a cast end time position. A bottom depth and depth above the bottom should also be tabulated A few obvious goofs are tabulated below but the table needs to be fleshed out and proofed carefully. The following are some specific problems that should be looked at: Station 8, btl. 2: Data listed at 2038db unlikely, but would probably be ok at assumed unlisted trip depth between 2038 and 1588db, perhaps near 1888db. Bottles 3 and 4 both listed at 1588db, suspect rosette hang-up started with bottle 2. Recommend data originators check to see if the data listed at a shallower depth would be ok and then change data flags. Station 9: Numerous trip errors, not all resolved. O2's not listed below 869db; they should be with appropriate quality codes. The data from bottles 2 and 9 are listed at odd pressure intervals, data would look ok if listed at pressures midway between bracketing bottles. Data from bottles 20 and 21 are essentially the same, suggesting both tripped at the same depth, perhaps near 815db according to the salinity gradient. If trip depth can't be resolved, recommend flag all water samples from bottle 20 uncertain also. Station 10, btl. 17: Salt, silica and O2 suggests data would be ok if listed at pressure about half way down to next reported pressure. If done, change quality flag to ok. Station 11, btl. 1: Increase in trench bottom O2 probably is real, see SCORPIO stas. 83 and 90. The trench is the main conduit to the bottom Eastern Pacific basins. Station 13: Suspect sample drawing errors: salts from bottles 6 and 7 flagged poor, would be ok in reverse order. No salt listed from deepest bottle. O2 from 20 was probably drawn from bottle 21. O2's from 6 and 7 clearly would fit better deeper in the water column. On second thought, salt, O2, and silica from bottle 7 would be fine one depth deeper; if that were done, the quality flags could be changed to ok. Station 16, btls. 8 and 9: Both salt and O2 indicate they tripped one depth deeper; nutrients ok at either depth. If moved accept data as ok. O2 from bottle 3 probably drawn from bottle 2, must "u" it at present depth. Station 17, btl. 8: Salt, O2 and nuts indicate bottle probably tripped at unlisted depth about half way down to next depth. Data ok if moved; if left as is, flag nutrients doubtful also. Station 19, btls. 5 and 6: Salt, O2, silica would fit better with adjacent Station and CTD O2 if water data moved up one depth. If done, change flags to ok. Station 31, btl. 6: Nutrients originally flagged bad, probably because they look a little high. However, O2 inflection agrees with nutrient profile, and the bottle O2 is confirmed ok by the CTD O2, so I've flagged all of the data as ok. Station 32 salts: All appear high compared to adjacent Stations THETA - S curves and the CTD, suspect faulty salinometer run. Recommend all be flagged questionable (not done yet). Station 41, btls. 3 and 4: Comparison of salinities with the CTD suggests samples were reversed in sampling. However, O2 was also bad on bottle 4, so only that depth was flagged, but bottle 3 salt could be also. Station 55, btl. 32: Is the reported oxygen of 14.120 ml/l a typo or the actual measurement? Seems unlikely to titrate a factor of 3 times too high. Station 64, btl. 21 O2: Clearly too high, but would agree with CTD O2 if a transposition error had occurred: 5.93 ml/l recorded instead of 5.39 ml/l. Should check with the original sources. .sum file, sta. 14: Probably on the 7th, rather than 6th. .sum file, sta 17: BO 8th, not 7th. .sum.file, stas. 21 and 22: Must have been on the 9th. .sum file, sta. 32: bottom date wrong, must be 13. .sum file, sta. 69: Longitude seems unlikely, 9 deg. off? ____________________________________________________________________________________________ ____________________________________________________________________________________________ G.3. DQE OF WOCE P06W HYDROGRAPHIC DATA (A. Mantyla) 7 March 1995 The P06W leg is the third and final leg of the WOCE section near 30S across the entire Pacific. All three legs were done using essentially the same equipment and methodology, so the DQE reports for the first two legs should be referred to for comments that are relevant to all three legs. The salinity and oxygen precision in the deeper layers was better than on the previous two legs, but there was still a surprising and unlikely range in the mixed layer at times. Rosette trip malfunctions also occurred less often, but bottle 31 was often involved in mis-fires. Phosphates were back on line this leg, with the exception of two stations (see below), the data looks quite good. The last 20 stations consisted of two repeat segments of the end of the P06 line ascending the Australian slope. The hydrographic data consisted of essentially just 12 CTD calibration samples, they have no value as hydrographic profiles and I recommend that stations 248 to 267 be omitted from the P06 data set. This section is a very nice improvement over the SCORPIO lines at 28 and 43S, I look forward to seeing the contoured sections. COMMENTS ON SPECIFIC STATIONS: Station 191, .sum: The position appears to be one degree too far south to be part of the section. Needs to be verified, or corrected. Station 195, btl. 31: Bottle malfunctioned on the last station and appears to have delay-tripped at the next depth up from its listed depth on this station. As tabulated, all of the bottle 31 water samples should be considered doubtful; but they would be ok if moved up a depth. Station 229, PO4's: Deeper phosphates are higher than adjacent stations, relative to the cruise NO3/PO4 relationship. Suggest data originators recheck the phosphate end standard factors and baselines to see if the data can be corrected. If not, flag data below 900db uncertain. Station 236, btls. 30 and 31 at 400 and 301db: Water sample data nearly identical, most likely both tripped at 400db. If bottle 31 moved to 400db, accept the data as ok; otherwise, flag all water samples questionable. Station 238, PO4's: Similar to station 229, deeper ones flagged questionable. Suggest re-check end standard factor and baseline to see if the PO4 data can be salvaged. Stations 248-267: The WOCE P06 section ends with station 246. The remaining 20 stations were two repeat sections of the last 1 deg 30 min. longitude done with a different CTD and a highly malfunctioning 12-place rosette. The hydrographic data from those stations have some slight value for calibration of the CTD, but are of no value as hydrographic profiles. I recommend they not be reported. The P06 section is complete with station 246, so the remaining stations are not needed anyway. ____________________________________________________________________________________________ ____________________________________________________________________________________________ G.4.

DQE OF WOCE P06 CTD DATA (NIEL White) 3 April 1995 On the whole the processors have done a good job with this cruise and this data set is a big improvement on the P16C data which I was sent last year. I do, however, have a few complaints. The principal one is the question of units t68 for temperature and ml/l for oxygen). I gather that the WHP office has taken this issue up, so I will not labour it here. The other main complaint is that I feel that the noisy oxygen data in the top part of the water column on leg 3 should have been flagged as questionable. The report states that investigators may need to average or filter the data to make it useable (p 11) 1. This sounds like a fairly good definition of 'questionable data' to me. TEMPERATURE CALIBRATION The temperature calibrations are described on pp. 30-31 and appendix D. I would still like to see an accuracy estimate based on a comprehensive error budget of the calibration procedure. I suspect that the difference between the pre- and post-cruise calibrations of CTD 9 are more a statement about the accuracy of the calibration lab than about drift in the CTD. SALINITY AND DISSOLVED OXYGEN CALIBRATION On the whole the data processors have done a good job of calibrating the CM salinity and dissolved oxygen channels. I was pleased to see that the processors had not used unphysical values for some of the calibration parameters (which they had used at times when processing the P16C cruise). For salinity (figure 1) and oxygen (figure 2) 1 have plotted profiles of scaled offsets between bottles and downcast CTD values. Deep offsets are plotted at a larger scale than shallow ones - the scale is shown by the two lines on the left hand side of each frame. At any depth the width of the wedge represents an offset (bottle - CTD) of .01 psu (figure 1) or 4 µmoles (figure 2). Note that only samples flagged as good data (quality byte = 2) are considered in this report. Deep salinity fits In general, deep salinity fits are good, except for the following stations: Where Station in group Problem ------- ----------- ------------------------------------------------------ 32 middle approximately .004psu fresher than bottles from 2,000m down 44 middle approximately .003psu fresher than bottles from 3,000m down 101 end approximately .002psu fresher than bottles from 2,500m down 114 middle approximately .003psu saltier than bottles from 3,500m down 120 end fairly poor fit from about 1,000m down - saltier for part of the water column and fresher deeper down 121-122 whole group both stations in the group seem to be on the salty side!! While these differences must, to some extent, be due to the tendency of the CTD data (fitted in groups) to smooth out variations in the bottle data, I think that these sections should be looked at again. Presumably the very short group of stations 121 - 122 was chosen because of difficulties fitting larger groups, but difficulties still remain. The deep CTD data for station 121 is a little salty compared to the bottles, but for station 122 it is substantially saltier. I find this intriguing! The report (p56 in appendix F) refers to a manual adjustment for station 122. Has this manual adjustment been done correctly? DEEP OXYGEN FITS I have used a scaling factor of 44.6595 to convert ml/l to molar units. I dare say that this is not the 'correct' way to do this conversion, but it will do for the purpose of this report. The processors seem to have done a generally good job of calibrating the deep oxygen profiles. Apart from some obviously bad bottles (e.g. station 106 at 4,001 decibars). The stations I would like to see looked at again are: Stations Problem -------- -------------------------------------------------------------- 17 & 18 consistent deep offset (~2 µmoles) for both stations 81 & 83 offset at the bottom 116 poor fit from -3,300 decibars down (bad bottle data?) 119 poor fit at the bottom - out by 2 - 3 µmoles 126 deep fit would be improved by removing the bottle at 4,571 decibars 131 poor fit from 3,600 decibars down 137-149 generally poor fits in deep water (deeper than 3,000 decibars) 155-161 the bottom section of most of these stations is offset 164-170 the bottom section of most of these stations is offset 173-178 fairly poor fits in deep water 234-237 fairly poor fits from about 2,000 decibars down I realize that, given the vagaries of the instrument, it may not be possible to do much with some of these. I feel, however, that they should be looked out again to see if some improvement can be made. SHALLOW (0 - 1,000m) FITS SHALLOW SALINITY FITS Figure 3 is a plot of comparisons of upcast CTD salinities with the bottles from 1 to 1,000 decibars and figure 4 is a plot of comparisons of downcast CTD salinities with the bottles over the same depth range. The scale is fixed through the depth range and is shown by the bars on the left of each figure. Most of the smaller offsets in figure 3 can be attributed to gradients, etc. The CTD salinity values referred to in this section are the burst values from the hydrology files except where stated otherwise. Fits are, in general, good, with the following exceptions: Stations Problem -------- ---------------------------------------------------------------------- 9 the CTD value at 66 decibars seems to be grossly wrong (= 31.368psu) and, apart from this, the fit is poor 88 surprisingly, salinities from the downcast fit the bottles better than the values from the upcast. I suspect that this is the result of a sampling or analysis problem and that these bottles should be discarded 90 the samples at 23 and 62 decibars seemed to have been interchanged - the fit is quite good if you swap them over! 97 the bottle at 156 decibars is clearly wrong 142 the bottle at 160 decibars seems to have a wrong depth - both downcast and upcast CTD values are offset from it by the same amount, and it looks like it would fit much better at a shallower depth. This is corroborated by the oxygen data. 155 similar comments to those for station 142 apply to the bottle at 111 decibars 174 similar again except that the bottle at 110 decibars looks like the depth is too shallow 177 similar again - the bottle at 159 decibars looks too shallow 222 the bottle at 305 decibars looks wrong - the downcast value fits better! 226 the bottle at 297 decibars looks wrong - the downcast value fits better 241 the downcast values fit better from about 200 - 500 decibars, suggesting a sampling or analysis problem SHALLOW OXYGEN FITS As stated earlier, my main problem with the shallow oxygen data is the use of the noisy data on leg 3. This data is clearly of questionable value. It is stated on p32 that this data is very difficult to fit. This is not surprising and I would suggest that the following steps be taken: either: the noisy data be filtered and, where believable profiles could be obtained the calibration calculations re-done or: the data be removed or flagged as questionable and not be used in the calibration calculations. The statement that surface spikes were common, but were not flagged is made on p32. Why weren't they flagged? This is, surely, questionable data and should be flagged appropriately. Figure 5 is a plot of comparisons of downcast CTD oxygens with the bottles from 0 to 1,000 decibars. The scale is fixed through the depth range and is shown by the bars on the left of each panel. It is hard to say anything sensible about the leg 3 data because of the above problems. The data for legs 4 and 5 looks quite good, given the limitations of the instrument. A number of the samples which look bad on these plots have, in fact, been fitted as well as can reasonably be expected -the offsets are due to downcast/upcast variability rather than poor fitting. However, I would like the following apparent problem areas to be looked at: Stations Problem -------- ---------------------------------------------------------------------- 80 bottle at 634 decibars looks quite wrong 119 bottle at 60 decibars looks quite wrong 160 bottle at 160 decibars is offset, but could be due to upcast/downcast variability 171-177 all generally poor fits 186 bottle at 207 decibars looks odd 232 poor fit in top 200 decibars 236 bottle at 202 decibars looks wrong 238 poor fit in top 400 decibars MINOR PROBLEMS THERE ARE A FEW MINOR PROBLEMS AND/OR ANNOYANCES WITH THIS DATA SET: • the record counts in some CTD fides are incorrect - for example, the header for station 9 says that there are 1,767 data records in the file. This would be correct if the data started at 1 decibar, but, as the data starts at 17 decibars it is not. In fact there are 1,759 data records (17 -> 3,533 decibars). • there are some bad interpolations. For example, the 'interpolated' salinity for station 12 at 38 1 decibars is .05 psu different from the salinities on either side (which are very nearly equal). The salinities for 379, 381 and 383 decibars are 34.4500, 34.4004 and 34.4508! Station 147, 1,909 -1,911 decibars is another example. How are these interpolations done? If they are being done manually they should be checked more carefully. In addition, the interpolated salinity at 1,931 decibars in station 147 is (a) badly interpolated and (b) not flagged as an interpolated value (flag = 2, not 6). Other bad interpolations or interpolations that have not been flagged correctly are station 151 at the surface, station 157 at 4,409 and 4,411 decibars, station 159 from 2,333 to 2,353 decibars. The flagging and the documentation are inconsistent for station 79. In addition, some of the end points that have been chosen for the interpolation seem odd. For example, the salinity interpolation from 4,565 to 4,603 decibars in station 164 seems to be between points where the salinity has already departed from the 'true' value. This is the second cruise I have seen where there have been a number of poor interpolations. If the WHOI CTD group are going to continue to provide interpolated data I think that they need to have a careful look at their method for doing this. I make no guarantee that I have found all instances of these problems. ____________________________________________________________________________________________ ____________________________________________________________________________________________ G.5. PI RESPONSE TO HYDROGRAPHIC DQE (DQE Arnold Mantyla reviewed the Hydrographic Data) SUM file: Bottom time and position added. Maximum pressure corrected. Corrected errors in stations 14, 17, 21, 32, 69, 191 DOUBLE TRIPS: A common problem with double trips is that although the CTD pressure and temperature were identical, for some reason the CTD salinity and CTD oxygen were not (probably due to the program that overwrites the old file with new data). These double trips were identified and the CTD salinity and CTD oxygen checked for accuracy. CTD, Salinity and Oxygen quality code changed: Agree almost entirely with DQE's suggested changes. SPECIFIC PROBLEMS: Station 8, bottle 2: Station log revealed no indication of a problem. Decided not to make up a new depth. If bottle did close at shallower depth then the bottle must have been closed while package was moving, which would also produce questionable results. Station 9: Changed trip depth of bottle 11 to indicate bottle 11 and 12 double tripped at bottle 12's depth. Changed quality word to good. Station log depths for bottles 2 and 9 agree with depths in water sample file (*.hy2). Oxygen water samples were not reported below 869db (lost in analyses?) thus 5 was used as the quality code. Trip depth not resolved, water samples (salt, oxygen and nutrients) marked questionable. Station 10, btl. 17: Did not change trip depth. Bottle was a leaker, water sample data left as questionable. Station 11, btl. 1: Oxygen looks too high in comparison to following stations that were also in the trench. Left oxygen quality code as questionable. Station 13: Changed trip depth of bottle 7 to reflect bottle 7 double tripped with bottle 6 at bottle 6's depth. Bottle 6 is a leaker, water sample data is questionable. Bottle 20 oxygen probably was mistakenly drawn from bottle 21 but left quality code as bad. Station 16, btls. 3, 8 and 9: Changed trip depths of bottles 8 and 9 to reflect bottle 8 double tripped with bottle 7, bottle 9 tripped at bottle 8's former depth and no bottle tripped at bottle 9's former depth. Changed bottle 8 and 9's quality code to good. Changed trip depth of bottle 3 to reflect bottle 3 double tripped with bottle 2 and no bottle tripped at bottle 3's former depth. Changed bottle 3's quality code to good. Station 17, btl. 8: Trip depth unresolved, flagged quality code of salt, oxygen and nutrients as questionable. Station 19, btls. 5 and 6: Changed trip depths of bottles 5 and 6 to reflect no bottle tripped at bottle 5's former depth, bottle 5 tripped at bottle 6's former depth and bottle 6 double tripped with bottle 7 at bottle 7's depth. Changed bottle 5 and 6's quality code to good. Station 31, btl. 6: Changed nutrient data quality code to good. Nutrient data analyzer, Joe Jennings will review change. Station 32: All salinity quality codes changed to questionable. Salinity analyzer, George Knapp did not find any reason to explain bad station data. There was no shift in the salinometer standby number. Station 41, btls. 3 and 4: Bottle 3 salinity flagged as questionable. Bottle 4 salinity and oxygen flagged as bad. Station 55, btl. 32: Oxygen analyzer, George Knapp remembers bottle 32 did indeed have an extremely high oxygen measurement. One wild guess is perhaps the iodine measured in the titration had been increased due to the ink of a squid?! Station 64, btl. 21: Coincidence perhaps, probably not a typo, in any case bottle 21 quality code left as bad. Stations 73 and 74: Instrument test stations only, not included in data set. Station 79, 1964db: Sample lost in analyses, quality code changed to 5 (not reported). Station 80, btl. 24: No mix-up found and unlikely a typo. Bottle 24 quality code left as bad. Station 81, btls. 7 and 8: Quality code of all nutrients for bottles 7 and 8 were changed to questionable. Nutrient analyzer, Joe Jennings will review this change. Station 89, btl. 20: Oxygen quality code changed to questionable. Quality code of deep silica's were changed to good. Nutrient analyzer, Joe Jennings will review this change. Station 90, btls. 35 and 36: Agree, that likely two surface salinity samples had been interchanged. No explanation found, so samples were not swapped, quality code was changed to questionable and CTD salinity quality code was changed to good. Station 95: Left trip depths as they were and changed quality code of oxygen and nutrient data to questionable. Station 97, btl.29: Salinity typo corrected, both salinity and CTD salinity quality codes were set as good. Station 101, btl.22 at 90m: Changed trip depth to reflect bottle 22 double tripped with bottle 23 at bottle 23's depth. Changed quality code to good. Station 104, btls. 10 and 11: Changed bottle 10 and 11's quality code to bad. Station 113, btl. 19: Original records show bottle was meant to trip at a depth near 250db. Changed trip depth, temperature, theta, CTD salt and CTD oxygen, to match original trip depth data. Changed quality code to good. Station 143, btl. 8: Original records show bottle was meant to trip at a depth 3967db. Changed trip depth, temperature, theta, CTD salt and CTD oxygen, to match original trip depth data. Changed quality code to good. Station 145, btl. 13: Changed bottle 13 trip depth to reflect bottle 13 and 14 double tripped at bottle 14's depth. Changed quality code to good. Station 147, btl. 8: Original records show bottle was meant to trip at a depth 4039db. Changed trip depth, temperature, theta, CTD salt and CTD oxygen, to match original trip depth data. Changed quality code to good. Station 148, btls. 11 and 12: Changed trip depth of bottles 11 and 12 to reflect bottle 11 double tripped with bottle 10 at bottle 10's depth and bottle 12 tripped at bottle 11's former depth. Changed quality code to good. Station 149, btl. 13: Changed trip depth of bottle 13 to reflect bottle 13 double tripped with bottle 14 at bottle 14's depth. Changed quality code of salinity to good but oxygen quality code left as questionable. Station 195, btl. 31: Changed trip depth of bottle 31 to reflect bottle 31 double tripped with bottle 32 at bottle 32's depth. Changed quality code to good. Station 229, PO4s: Changed PO4s quality code to questionable for all observations below 900db. Nutrient analyzer, Joe Jennings will review this change. Station 236, btls. 30 and 31 at 400 and 301db: Changed trip depth of bottle 31 to reflect bottle 31 double tripped with bottle 30 at bottle 30's depth. Changed quality code to good. Station 238, PO4s: Nutrient analyzer, Joe Jennings will review. Stations 248 through 267: Stations are along cruise track and are considered part of the data set. ____________________________________________________________________________________________ ____________________________________________________________________________________________ G.7. PI RESPONSE TO CTD DQE (DQE Neil White reviewed the CTD calibrations) Units: The proper temperature and oxygen units have been converted by the WOCE office. Leg 3 shallow oxygen: Did not filter nor flag as questionable. The problem with the CTD oxygen and the surface spikes are described in the notes. Temperature calibration: Information about the temperature standard's accuracy used in the calibration has been added. DEEP SALINITY FITS Station 32: Discrepancy due to bottles that were questionable, did not change the CTD data. Station 44: CTD data theta-salinity plots overlaid stations 41, 42 and was only .001psu fresher than station 45. Did not change CTD data. Station 101: Changed CTD salinity by +.001psu. Desired good match at 2ØC theta with surrounding stations. Station 114: Discrepancy due to bottles that were questionable, did not change the CTD data. Station 120: Discrepancy due to bottles that were questionable, did not change the CTD data. Station 121: Discrepancy due to bottles that were questionable, did not change the CTD data. Station 122: Changed CTD salinity by -.002psu. Original fix of +.004psu had been too much. DEEP OXYGEN FITS Stations 17 and 18: Refit the CTD oxygen below 1500 db. Stations 81 and 83: Bottom CTD oxygen quality code changed to questionable or bad. Station 116: Discrepancy due to bottles that were questionable, did not change the CTD data. Station 119: Refit the CTD oxygen below 3000 db. Station 126: Bottle flagged as questionable. CTD oxygen was not changed. Stations 131, 137- 149, 155- 161, 164-170, 173-178, 234-237: All of these stations had problems with deep oxygen fits. Refit the CTD oxygen below 3000 db for not just these stations but the whole group from 131 through 178 and 232 through 240. The CTD oxygen data from the new fit was put into the existing file replacing the existing deep CTD oxygen. The new and old oxygen were blended +/- 50 db around the transition point (usually 3000 db) to keep the profile smooth as it changed from the existing oxygen to the new oxygen. The new fits look good. Even after this second fit though, station 175 CTD oxygen below 5500 db did not look good, so its quality code below 5500db was changed to bad. SHALLOW SALINITY FITS Station 9: CTD salinity at 66db and next observation deeper quality codes changed to bad. Station 88: CTD salinity quality code changed to questionable. Station 90: Did not interchange bottle samples, left quality code as questionable. Station 97: Changed quality code of bottle salinity at 156 db to questionable. Station 142: CTD trip depths changed. Bottle 33 changed from closing at 160 db to closing at 111db. Bottle 34 changed from closing at 111db to 62db. Bottle 35 changed from closing at 62 db to 22 db. Bottle 36 did not close. Station 155: Changed quality code of CTD salinity at 111 db to questionable. Station 174: Changed quality code of bottle salinity and oxygen at 110 db to questionable. Station 177: Changed quality code of CTD salinity at 159 db to bad. Station 222: Changed quality code of CTD salinity at 305 db to questionable. Station 226: Changed quality code of CTD salinity at 297 db to questionable. Station 241: Changed quality code of CTD salinity to questionable and bad for observations at bottles 17, 18 and 19. SHALLOW OXYGEN FITS Leg 3 shallow oxygen: Did not filter nor flag as questionable. The problem with the CTD oxygen and the surface spikes are described in the notes. Station 80: Changed quality code of bottle oxygen at 634 db to questionable. Station 119: Changed quality code of bottle oxygen at 60 db to questionable. Station 160: Changed quality code of CTD oxygen at 160 db to questionable and at 111 db to bad. Station 171 through 177: For stations 171 through 174, CTD oxygen was refit for better fit 0 to 3000 db. Used separate deep water fit for scaling data 3000 db to bottom. For stations 175 through 178, corrected typo in oxygen current bias scaling term and re-scaled data. Station 186: Changed quality code of CTD oxygen at 207 db to questionable. Station 232: Changed quality code of CTD oxygen at 15 db to bad. Did not change fit. Station 238: Changed quality code of CTD oxygen at 20 db and 160 db to questionable. Did not change fit. Minor Problems Record counts in *.CTD file headers were changed to accurately state how many records were in the file. Interpolations corrected. Main problem appeared to be the discrepancy of what interpolations were recorded in the station by station notes and what was actually done, recorded in the list of interpolations made to CTD data. Problems the DQE noted were and further discrepancies found were corrected. ____________________________________________________________________________________________ ____________________________________________________________________________________________ H. NOTES ON THE KNORR ANALYTICAL LAB 1. Temperature stability: There is a separate thermostat for the analytical lab and it does work; however the tolerance seems too wide. We recorded the temperature continuously for several days and the thermostat cycle has an amplitude of about 3 degrees C with a period of about 30 minutes. Closing the after door to the lab did not noticeably change the period or amplitude. (There is a plastic draft barrier on the after door which has been in place continuously.) The mean temperature for the past two months has been around 23 C, but there have been brief periods when the temperature has climbed to 27 degrees. 2. Power: There were several complete power failures on the "clean power" circuit during P06 legs 1 and 2. We also suspect, but cannot verify, that power fluctuations contributed to the failure of two DC boards in the RFA during leg 2. I would strongly recommend the use of UPS systems and/or line conditioners for all computers and other sensitive equipment. 3. Water quality: The ship's tap water is frequently discolored, presumably by iron. We compared the tap water with water directly from the evaporators and directly from the RO system. The tap water had almost 0.4 micromolar phosphate, about 7 micromolar silicate, and negligible nitrate and nitrite. The RO water was better than tap, but still had measurable phosphate and silicate. The evaporator product was almost indistinguishable from our deionized water (DIW), so we decided to use it as our feed water for the deionizer. This has meant filling several 5 gallon carboys at the rear of the main lab every few days and pumping these through the deionizer as required to fill our 10 liter DIW reservoir. If a clean water line were run directly into the analytical lab, it would be much more convenient. This should be a simple matter as there is a supply of evaporator water to the main lab already. There is a small deionizer installed in the after corner of the main lab. It does not seem to be connected to a water supply, and I don't know which institution it belongs to. I would not rely on it for deionized water. 4. Space: We have used the forward bench for the nutrient analyzer, stripchart recorders, and a small data acquisition computer. The forward inboard bench has our data processing computer, printer, and plotter. The fold-down after inboard bench is desk height and has been great for reading stripcharts and general paperwork. I don't know how much weight it will bear. The after bench has a space 44 inches wide and about 30 inches deep next to the fume hood which could accommodate additional equipment. We have used the entire outboard bench with it's sink for sample handling and reagent preparation, but this area could easily be shared. Joe Jennings, R/V KNORR, 7/25/92 ____________________________________________________________________________________________ ____________________________________________________________________________________________ APPENDICES APPENDIX A: Station positions and summary (not available at time of last update) APPENDIX B: Comments regarding CTD data acquisition: LEG 3: ===== Aqui89 troubles from the start of leg3. Code got corrupted and was scrambling the last three parameters (TP,TR,RT). Plotting of extra variables and derived parameters was demonic. Test station 999 and 998, and station 1 were acquired with this corrupt code. A backup AQUI89 tape from July 1991 was restored to the microvax and station 2 was acquired with this code. Data clean. Plotting spikes for TE variable. Station 1 was replayed from microvax rental, stations 11-17. Test station 999 supplied too much power to fish, noise at bottom when firing. Switched to battery, powered off lambda. Pressure spikes apparent test station 998. Believed to be from pinger. Station 1 and 2 were deployed with no pinger to test this hypothesis. Verified. Pinger moved on rosette frame prior to station3, no spikes. Triple cast in Chilean trench. Station 1-ctd No. 10, station 2-ctd No. 7, station 3-ctd No. 9. Decided to go with ctd 10. Ctd 7 bad oxy sensor, cond noisy deep water. Ctd 9 equally as good as 10 but consensus was to use 10 because of oxy pump. Ctd 10 showed some cond hysteresis at theta of 2.3-2.8 deg on co vs. te plots but t/s showed no up/down differences. Bob said diff in co attributed to diff in pressure. Up/down different by 30dbar. Replaced Oxygen sensor on ctd10 prior to station 4. Power outages and total blackout prior to station 8. CTD02 and CTD03 both crashed. Early on, CTD03 had repeated crashes, at start of cruise and in port in Jacksonville. Thought to be UPS, power or Ethernet related, one user logged off "mike" ship's Ethernet at the same time during one crash. Cause indeterminate. Noticed aqui record tags off by 50 dbars from deck unit readout on station logs. Changed average number of scans in template file from 5 to 1 station 9 to no avail. Aqui tags were always higher than deck unit readouts, indicating that the system was somewhat slow, lagging behind the current scan. Quick fix: tagged 1 min after firing. Worked okay. Logged to CTD04 (latest version of P06 code that was corrupt on CTD03) stations 11-17 to compare bottle tag files. CTD04 tag files were right on the mark, and furthermore, the last 3 channels were not scrambled. CTD03 crashed stations 12, cast 1. Restarted aqui cast 2. CTD03 crashed again station 13, but logging to CTD04 so didn't restart CTD03 again. Crashes seemed to indicate Ethernet problems. User logged out from "mike" on ctd02 station 12 at exactly same time ctd03 lost connection. Coincidence? Tagging offset also suggested that Ethernet was perhaps slowing the system down. Decided to disconnect from ship's Ethernet and create own ctd network. Restored P06 AQUI89 code on CTD03 on 6 May and acquired station 14 with the same code. Ctd04 logging in tandem as backup still. Station 14 was clean and tag files were right on the mark. Aqui plotting code re-linked and recompiled May 8. Seemed last fix to software had bug in it, so went back to plotting code just prior to last fix. Aqui89 code modified May 12 to add extra column in redt temp field in .WRW tag file to avoid integer overflow. Station 17, CTD03 crashed again. Likely culprits: HE/TRitium van or NUTS Ethernet cables, or UPS/ship power problem. He/Tr van was not working when hooked up through hydrovan to ctd network to ships network. Disconnected He/Tr cable, wired directly to ship and Ethernet working fine. Thought He/Tr and hydrovan had an interrupt or board conflict. Winch failed station 21 3500 m on upcast. Only 3 bottles fired. Brake froze. CTD sat 500 m off bottom for 5-6 hours before got working again. Switched over to markey winch station 22. After record tags edited manually and templates distributed, discovered numerous double tripping of bottles. Just about every station through station 22. Changed pylons prior to station 23 which proved successful. Station 27 new co slope. Markey winch failed 700 m upcast station 27. Cast aborted. CTD had to be brought on deck manually. Switched back to first winch. Required second person to manually operate brake. After recovery on station 28, CTD endcap opened. Seacon 4 pin bulkhead connectors replaced. Aqui locked up station 30 for about 2 minutes, no data written to tape. Station 31 CTD03 threatened to lose connection to cluster (ctd02) again. Immediately disconnected Nuts Ethernet cable and regained instantaneous connection. Decided to disconnect NUTs cable and hook up only during steaming. Days later, replaced Nuts cable with a different cable. Hydrovan could not log in when this cable was connected. NUTS Ethernet address in conflict with one on ship in SSG group. Changed name and address. Should not have been the cause of crashes since no conflict with ctd network. Days later, can have both nuts and hydrovan on net with no conflicts. It was believed at end of leg3 that He/Tr van had a bad cable. New pinger station 36. Swapped redt temp modules station 59. New pressure temperature cals ctd 10. Revised aqui template station 60. Also cleaned conductivity cell with HCL prior to station 60. Watch forgot to increase seacableI to 470ma on downcast start station 61 until approx. 500 m down. Oxygen erroneous and erratic first 500 m. entire cast. Winch troubles again station 63. Flipped circuit breaker, power restored. Restart cast 2 at 10m. Lost power one more time before cast completed. Error writing to 9-track station 65. Did a stop_watch, logger hung. Tried to force and restart several times with no success. Killed grabber, re-executed sysmgr commands and restarted aqui, cast 2. Tape and disk okay, but no header file on disk. Same error to 9- track station 69. CTD_LOG in RWMBX state, can't force or stop_aqui, only stop/id works. Test rebuilt markey winch station 69. Turn off oxygen pump station 70. Pump flow facing up on last two station 71 & 72. Oxygen noisy, as on station 70. Rotate back to face down on Leg4. Bottom (PDR) depth vs. pressure discrepancies: station 11,23,36,38, 43,45,47,56, 57,67. 56 & 57 drifting over slope, false bottom readings? Trouble with 9-track last two stations. End of leg3, during swim call, UPS's went on alarm, all 3 systems crashed. Believe 9-track troubles might have to do with power. LEG 4: ===== Surge suppressor on aqui 9-track. CTD02 and CTD03 on UPS on clean power. Repacked hard disk dua4 for acquisition. Reoriented oxygen pump outtake on ctd10 to face down. Double cast station 73 (ctd 7) and 74 (ctd 10) in same position as station 72 on leg3. Attempted to first deploy ctd 9 at station 73, fatal failure. Troubleshot to power supply board. CTD 7 deployed with old oxy sensor (bad). Conductivity still looks noisy as compared to ctd 10 and ctd 9. Slight hysteresis in deep water t/s plot. CTD 10, station 74, lowered with not enough current to fish. Data noisy. Cond appears to be offset, oxygen looks offset and has different shape. Omit these two station 73 & 74 from final ctd data set. Record tag data erroneous scans station 74. Became apparent ctd 10, 9, and 7 wired differently. Transmissometer cable different for each instrument. Fatal failure ctd 10 prior to station 76. Switched over to ctd 9 with new power supply board and no oxy pump. Scot touched case and got zapped, ctd underwater cable bunged up. Replaced with new one. Signal still noisy. Ground lug on termination broke off (corrosion), and had to be replaced. Finally deployed ctd 9. Interference on upcast when firing bottles. PHANTOM problem -comes and goes. Upon examination, sea cable bulkhead connector corroded ctd 10. Salt deposits found at both end caps. Battery pack shot with salt and corrosion. High voltage pin had corroded from getting wet because non- watertight plug was used for charging between stations on leg3. Epoxy connector broke down and water wicked in through the pin. Had been going on for a while on leg3. Just got lucky that ctd 10 lasted through leg3. Took out battery pack and dc-dc regulator. Removed battery fuse (not needed anyway because separate conductors for ctd and rosette). Oxy pump board burnt. Power converter died. Need replacement. Jeff rigged up transistor circuit to replace original power converter, but 10 was rushed back into service before he could get the pump board fully checked and installed. Station 78, switched over to battery for power supply to fish to try and eliminate interference problem (ctd 9) but battery died on upcast. As a result, upcast poor data quality esp. last 12 bottles, i.e. 600 m. Winch died 1880m downcast station 79. Gap in data. Need to ctlog CU mode back at clark 1880-2100m. Switch over to markey winch station 86. Upon recabling to second termination, ctd 9 redt temp out. Disconnected and when plugged back in, oxy sensor failed. Deployed CTD 10 in its place. Later, when ctd 9 powered up in wet lab, all checked okay. DIED again a few days later. Further examination revealed inept wiring, poor soldering (shoddy workmanship). Replaced sign gen and adaptive sampling boards. Power still flaky. Checked voltages and found that sometimes the 6V from ctd power supply was drooping because of excessive loading effects. Both the 2 channel digitizer and the otm board use this 6V along with the ctd comparator and adaptive sampling. Since this regulator current limited to 40 mA, it really doesn't have enough poke to handle the load. Fix was to take the 5V regulator on the OTM board (which uses the 6V as input) and run it from the 12V regulator located on the same (otm) board, instead of the ctd 6V power supply. Now ctd 9 running like a champ. CTDs seem to be right on the margin of being overloaded in terms of power. If put ctd 7's otm card in place of 9's (before the fix), ctd 9 would work. Implies juice marginally available, ctd highly sensitive to minor fluctuations. CTD 10 looking better Leg4 than leg3. Conductivity more consistent. Oxygens fitting much better without pump. Leg3, oxygen noisy 1st 400 m with pump. Also, hard to fit oxygens at oxy mins and maxes and in deep water on leg3. Not sure whether problems related to ctd going south, or problem with pumping mechanism, or simply because gradients much sharper on leg3 than Leg4. Vaxes crashed station 91, last record tag. Open data files aqui. Replay from audio. Engineer checked clean power with scope, believes one of lines has contaminated ground. STA 95,97-99 offset bottle data. Changed pylons and rosette firing units prior to station 102. Cond shift ctd between station 102 and 103. Inner rosette fired first station 108-111,113-114. Upon recovery station 110 (rough seas), package hit hull before top ring on package finally hooked with pole. As package brought on deck, air tugger bent frame (top ring) and deformed it. Vertical bars a nightmare. Station 112 deployed with ctd No. 9 using 24 bottle rosette. No transmissometer, no room for it on package. Oxygen failure on downcast. Conductivity noisy bottom of downcast, failure after 1st bottle on upcast. Numerous leakers. Salts poor, oxygens horrendous. Overall, station almost a complete loss. Upon examination, ctd 9 showed sensor head flooded with water. Sensor head rotated prior to deployment to accommodate new package. Further examination revealed that No. 9 tty fsk board wired to wrong pin. Couldn't just swap out boards between instruments. Miracle any data was ever collected with this instrument! CTD 9 back on line 6/17/1992. Upon recovery station 113, ship took roll at 40 m on upcast. Tow line got caught in propeller. Blocks hit boom and broke off. Vertical bars now almost impossible to put in place. Wire also came up with a kink in it. New termination prior to station 114. Upon recovery of station 114, cable came up with new kink. Vertical bars taken off rosette package station 115. Replaced with 2 horizontal bars at bottom of package. New top plate on pylon prior to station 116. Due to inclement weather and decreased ship speed (40-45 knot winds, ship cruising speed of 3 knots) and down time for hardware problems, spacing between stations increased from 40-50 nm after station 116. Swapped back in 36 bottle rosette deck unit prior to station 120. Previous unit (Scripps) had message on grate saying problems with firing. Power outage, vaxes brought down 6/16/92 for one hour. Back on line for station 121. Co shift ctd station 121. New termination prior to station 122. 3rd horizontal bar also put on package. CTD02 CRASHED 6/17/92, after recovery station 122. 6/17/92- ship on two engines, speed to station increased to 11 to 12 knots. 6/17/92 discovered that just 15 min prior to previous day's power outage, hydrovan got shift in salts (fresh) while running autosal. Reran afterwards, same samples now saltier. Apparently, autosal hooked up on 440 transformer (unreg power) with no UPS or surge protection. Will hook up to clean power and run off BEST UPS in helium van. Accounts for repeated shifts in salts and scatter for both legs3 and 4. STA 124 SWAPPED OUT AUTOSALS. Using autosal No. 10. Bath was leaking, had to be taken apart and re-glued before using. T/S anomaly starting at station 128. Saltier in deep water. Markey winch station 133. Lost power to winch during cast 3-4 times. Switched back to AB Johnson winch station 134. Vaxes crashed on downcast 700m off bottom station 136. Plugged terminal into UPS on aqui, powered off and completely shut off UPS and power to ctd03. Minutes later, ctd02 crashed. Rebooted systems, logged rest of station as cast 2. Replayed downcast from VCR tape. 9- track went offline, error msg, manually put online and logging resumed. Touched bottom station 137. Muddy water seeped out of frame upon recovery. Wire came up with two kinks. Cond shifted station 138. Winch failed at bottom of downcast station 139. CTD package dragged on bottom until ship increased speed to increase wire angle. Increased ship speed (12-13 knots) and increased speed at haulback of ctd (80 m/min) warranted changing station spacing to 40 nm again after station 139, until mooring line. Station 141 (ctd No. 9) and 142 (ctd No. 10) double cast. Test resurrected ctd No.9. Performed like a champ. Funny oxy blip. New 24 bottle pylon station 141 to try and alleviate non-confirmations for bottles 11 & 12. Kinks in wire warranted new termination station 145. Took vaxes off UPS to reset from home to generator mode. Widened frequency window. Systems back on UPS station 148. Hangar hoist repaired prior to station 150. Upon recovery of station 149, control handle cable pulled out, lead disconnected. Had to Reengage strain release boot. After switching pylons at station 141, became evident 24 bottle rosette double tripping. Swapped out 24 bottle pylon back to original. Replaced bulkhead connector. No more double trips. Station 156, error logging to 9-track. Log upcast as cast 2. Upon recovery, found cable between ctd and rosette caught in bottle 35. Ok. Disable transmissometer station 156-179, spec'd out to only 5500 m. Power failure prior to station 157. Ctd lifted off deck. 9-track offline. Brought ctd back to deck. Stopped aqui. Power outage. Systems stayed up on UPS. Power came back on, restarted station. Believe power to have been cause of problem (9-track going offline) on station 156. 9-track has narrower window of frequency operation than UPS's. Spikes at 2100,4400,5500 dbars station 156-167 on down and up cast. Erroneous tags in .wrw file. Cable appears to be cause. Prior to station 168, swapped ctd signal and 12 bottle pylon conductors. No more spikes, data clean. Kermadec Trench station 174-175. CTD taken down to approx. 6900 dbars. CTD pressure transducer maxed out at 6553.5 dbars. Spike in co, te, and ox at ] bottom. Pressure for last two rec tags estimated from wire out. Could be off by 15 dbars. Prior to station 179, took out large air bubble in ctd 10 oxy sensor. Refilled with oil. Transmissometer on again station 180. Station 182 EAST longitude. Fired inner rosette first station 183,185,188. AQUI89 mag tapes recorded on low density (800 bpi) station 185 & 186. Double cast station 187 (ctd 9) and station 188 (ctd 10). Station 187 had another funny oxy blip similar to 141. Could not fit ctd oxygen to bottle oxygen station 187. Recommend new oxy sensor if ctd 9 used on leg5. Conductivity looks fine. At end of leg4, rosette troubles. Getting confirmed firings but pins not releasing because sticking due to salt deposit buildup. Pylon was not being lubricated regularly. Sprayed liberally with CRC station 185. Bottles 23 & 24 not confirming. Believe cause is harness plug. Pete will replace prior to leg5. Realigned motor housing on two backup pylons, now ready to go if need be. LEG 5: ====== At dock in Auckland, the DEC software Licenses expired. This killed things like mail (critically necessary for AQUI), Fortran compilers, and communications (ftp and telnet). Apparently the microvaxes were shipped before the current license upgrade got to WHOI, so were not upgraded.... Tom B. Warren and Cyndy all assisted with sending along the appropriate fixes. thank god for Fax & telex. Necessary operations were back up before leaving Auckland at 1600 July 13 (but it was close). Stations 189 & 190 were repeats to 187 & 188 at the end of leg4. 187 and 189 were with ctd 9, 188 and ] 190 were with ctd10. Ctd10 still looks fine, so will continue to use with no modifications. Stn 201 Crashed CTD (60m/min) because missed a wrap on the pdr. The only obvious problem was that the bolts securing the ctd to the frame had sheared, and the ctd itself was loose on recovery. Swapped to the other winch while re-terminating, but just as got the fish in the water the power went off on the winch, and so had to wait for Peter to -terminate. Post crash numbers look pretty good. There's a slight salinity shift in the deep water, that John thinks is due to conductivity shift, not temperature. (the FSI ctd's temp offset is what it was pre-crash) BOTTOM CONTACT: Station 137,139 : 201,252 PROBLEM STATIONS: Tag files station 74, 78 & 112. Power low, erroneous tags. Recreated from raw downcast data. Downcast 1800-2100 station 79 due to winch failure. Need to ctlog cu mode cut and paste. Station 112- no oxy downcast. Cond noisy end of downcast, failed on upcast. Sensor head flooded. No bottle data station 141 test ctd 9. Could not calibrate oxygens. Test ctd 9 again station 187.

FITS FOR CTD OXYGEN ********************************************************************* CTD10 CTD10 CTD10 CTD10 CTD10 CTD10 CTD10 CTD10 ********************************************************************* LEG 3 CTD10 CHILE TO EASTER ISLAND STATIONS 4-72 Leg3 had an oxygen water pump attached to CTD 10. The data was noisy, especially at the surface. More serious, fits to the water sample data using data over the full water column were left with significant depth dependance in the oxygen - water sample residuals. The pressure dependence in the fit was removed from the final data by fitting the top and bottom water seperately. All stations have one calibration for the top 1000 dbar and a second calibration for the data below 1000 dbar EXCEPT for stations 4,5,70,72-75. Stations 4 and 5 do not have data below 1000 dbar and stations 70, and 72-75 fit well with one calibration for the entire depth. Stations 72-75 and perhaps 70 did not use the oxygen pump. Operationally a full water column fit was performed and the derived parameters applied to the top 1000 m of the water column to obtain one estimate of the oxygen profile. Next a fit was done only to the data below 1000 db, and these parameters used to derive a second oxygen profile estimate. The reported profile is a blend of these with a linear overlap region within 100 dbar vertically of 1000 db.

Comments ------- ------------------------------------------------------------------ 1 Test station 2 Test station 3 Test station 4 Surface spike in salinity. 1,3 dbar salts marked bad. Refit station 4's oxygen data by itself. Formerly stations 4 and 5 fit together. 5 Surface spike in salinity. 1 dbar salt marked questionable. 6 Oxygen too high, adjusted by -.04ml/l in CTD and SEA file. 7 Deep water spike in salinity. Interpolate salinity 1233 to 1251db. 8 Spike in salinity. Interpolate salinity 171 to 185. Spike in salinity. Interpolate salinity 1825 to 1843. Spike in oxygen. Interpolate oxygen 1819 to 1847. 9 Jump in oxygen, -.04 from 1.55 to 1.65 deg.theta. Could be real, quality word left at 2. 10 Surface spike in salinity. 1,3 dbar salt marked bad. 11 12 Initially missing top 400 meters of data due to beginning bad records in raw data being interpreted as beginning pressure by the pressure averaging program. Top 400 meters recovered. Spike in salinity. Interpolate 381db salt. CTD oxygen does not agree with bottles. Mark top 57 dbar as questionable. 13 14 Surface spike in salinity. 1 dbar salt marked bad. 15 CTD oxygen does not agree with bottles. Mark top 79 dbs as questionable. CTD oxygen might be off around 5 degrees theta, unclear from bottles, CTD quality word left as good. 16 CTD oxygen does not agree with bottles. Mark top 57 dbar as questionable. 17 18 Deep water spike in salinity due to incorrect data at end of file. The pressure averaging program interpolates all the 2db bins between last good point and first bad point adding ~200 dbar of bad information which goes below the ocean floor. The bad data at the bottom of the file were removed. CTD oxygen does not agree with bottles. Mark top 81db as questionable. 19 20 Spike in salinity. Interpolate salt 223 to 231db. CTD oxygen does not agree with bottles. Mark top 73 dbar as questionable. 21 22 23 Wayward salinity. Interpolate salt 67 to 73 db. CTD oxygen does not agree with bottles.

Mark 1,3 dbar salts as bad. 26 CTD oxygen does not agree with bottles. Mark top 73 dbar as questionable. Tried to refit CTD to match deep bottles better. No better fit found so fit left as it was. 27 CTD oxygen does not agree with bottles. Mark top 93 dbar as questionable. 29 Deep water spike in salinity. Interpolate salt 1637 to 1761 dbar. 31 Deep water spike in salinity. Interpolate salt 2041 to 2059db. Deep water spike in oxygen. Interpolate oxygen 2045 to 2053 db. 32 Surface spike in salinity. Mark 1,3 dbar salts as bad. CTD oxygen does not agree with bottles. Mark top 83 dbar as questionable. 33 CTD oxygen does not agree with bottles. Mark top 67 dbar as questionable. 34 CTD oxygen lower than bottles at 2.6 deg.theta. Doesn't look quite right but quality word left as good. 36 CTD oxygen does not agree with bottles. Mark top 75 dbar as questionable. 37 CTD oxygen does not agree with bottles. Mark top 65 dbar as questionable. 39 CTD oxygen does not agree with bottles. Mark top 73 dbar as questionable. 40 CTD oxygen does not agree with bottles. Mark top 101 dbar as questionable. 41 CTD oxygen does not agree with bottles. Mark top 73 dbar as questionable. 42 Surface spike in salinity. Mark 1db salts as bad. Theta salinity plot shows looping. Changing water (fresher than 41 and 43) may add to variability? 44 CTD oxygen does not agree with bottles. Mark top 65 dbar as questionable. 46 CTD oxygen does not agree with bottles. Mark top 87 dbar as questionable. 47 CTD oxygen does not agree with bottles. Mark top 189 dbar as questionable. 49 CTD oxygen does not agree with bottles. Mark top 87 dbar as questionable. 50 CTD oxygen does not agree with bottles. Mark top 123 dbar as questionable. 51 CTD oxygen does not agree with bottles. Mark top 79 dbar as questionable. 52 CTD oxygen does not agree with bottles. Mark top 52 dbar as questionable. 53 CTD oxygen does not agree with bottles. Mark top 113 dbar as questionable. Mark oxygens in deeper region for same reason, 555 to 799db. 54 Deep water spike in salinity. Interpolate salt 3177 to 3183db. CTD oxygen does not agree with bottles. Mark top 85 dbar as questionable. 56 CTD oxygen does not agree with bottles. Mark top 95 dbar as questionable. 57 Station 57 oxygen data refit by itself. Formerly fit with stations 46 to 57. 58 CTD oxygen does not agree with bottles. Mark top 159 dbar as questionable. 59 Small surface spike in salinity called ok- spike has changed theta which makes it much more likely to be real. CTD oxygen does not agree with bottles. Mark top 231 dbar as questionable. 60 CTD oxygen does not agree with bottles. Mark top 131 dbar as questionable. 61 CTD oxygen does not agree with bottles. Mark top 161 dbar as questionable and 423 to 775 as questionable. 62 Surface spike in salinity. Mark 1-5db salts as bad. 63 Spike in salinity. Interpolate salt 535 to 581db. Gap in data. Interpolate temperature, and salinity 535 to 581 dbar. Interpolate oxygen 531 to 589 CTD oxygen does not agree with bottles. Mark top 213 dbar as questionable. Stations 62, 64 and particularly 63 show more noise at depth than other stations in the oxygen profile. Could be due to non uniform lowering rate associated with poor sea state. 64 CTD oxygen does not agree with bottles. Mark top 251 dbar as questionable. 69 Spike in oxygen. Interpolate oxygen 81 to 105db. 70 to 72 Oxygen is noisier than usual, especially station 72. Salinity profile also has more looping in it. Both salinity and oxygen showing noise and loops supports the thought that the noise is caused by nonuniform lowering rate due to bad weather or big seas. The lowering rate varies from .5m/s to 2m/s unlike station 69 where the lowering rate was fairly consistent at 1m/s. 71 CTD oxygen does not agree with bottles. Mark top 151 dbar as questionable. 72 Seeing loops in theta salinity plots. LEG 4 75 Looks like it is on its own in theta salinity plot but it is consistent with station 71 which is moving between station 72 and 75. 76 to 78 refit. The bottom oxygens were not matching the bottles. The original fit was from a larger group 76 to 85. 78 Oxygen does not reach oxygen minimum defined by bottles at 3 degrees theta. 79 Large gap in data. Winch died near 1880 dbar. CTD stopped logging at this depth and was not started again until 2100db. Fix: Linear interpolation of temperature from 1879 to 2109 db. Salt and oxygen information copied from station 78 at matching theta intervals. Salt replaced from 1831 to 2401 dbar. Oxygen replaced from 1831 to the bottom. Oxygen does not reach oxygen minimum defined by bottles at 3 deg. 80 Oxygen lower than bottles at 7 deg. theta. Quality word not adjusted. 81 Bottom spike in oxygen spanning 3127 to 3393 dbar. This corresponds to the change in the rate of decent as the CTD approaches the bottom. This was checked and found true for 84 through 87 as well. 93 to 97: Variability in oxygen profile increase. Due to sea state? 101 and 102: CTD oxygen appears high from 8 to 14 deg.theta by .1 ml/l in both stations 101 and 102 111 Refit oxygen in station 111 by itself. Formerly in group of stations 111,113, 114 118 and 119: CTD oxygen in 118 and 119 is marginal between good and questionable , low from 3 to 8deg.theta. Quality word left as good. 119 Bottom oxygen drifts high from bottom five bottles. Marked oxygens as questionable throughout the drift, 4661 to 5620 db. 124 Refit oxygen be itself. Formerly fit in group 120 through 124. 128 Abrupt change into new water. 130 Deep water spike in salinity.

Mark 1,3 dbar salts as questionable. 135 Surface spike in salinity. Mark 1,3 dbar salts as questionable. 136 Acquisition computers crashed 700 m off the bottom. Acquisition halted and resumed. When resumed, oxygen had changed to a lower oxygen by .04 ml/l. Marked oxygen quality word as bad from 4905 db, where the jump occurred to the bottom. 137 to 142 bottle oxygens appear low, CTD oxygens are consistent with earlier stations. 137 Surface spike in salinity. Mark 1,3 dbar salts as questionable. Station +.002 psu than other stations. Salt slope reduced in calibrations files. 139 Spike in salinity at bottom of cast. Mark last data point as bad. 143 Surface spike in salinity. Mark 1,3 dbar salts as bad. Big surface spike in oxygen. Mark 1 dbar oxygen and temperature bad. 145 to 150: Refit oxygens in this group to get bottom oxygens to match bottles. Bottom oxygens now match better although top , near sea surface looks a little worse. 147 Data has gap where there were no observations 2259 to 2313db. Salinity spikes. Interpolate salt 1903,1909,1911,1931,1991, 2067-2085, 2093-2097, 2013-2027, 2157-2171, 2181-2189, 2257-2321db. Oxygen spikes. Interpolate oxygen 2073 to 2133 and 2257 to 2321db. Temperature was also interpolated over this range. 148 Bottom oxygen spike. Mark oxygen as questionable 6400db to bottom. 151 Surface spike in salinity. Mark 1,3 dbar salts as bad. 156 to 167: show two systematic spikes (small, around .002 psu) occuring near 2300db and 4400db. Interpolate over salt spike 5511 to 5545db. 156 Gap in data.

Mark 1 dbar bad. 157 Interpolate over salt spike 4409 to 4411db. 158 Gap in data. Interpolate over gap for temperature, salt and oxygen from 5521 to 5559db. Interpolate over additional salt spike 4415 to 4449db. 159 Interpolate over salt spike 2333 to 2353db. Interpolate over oxygen spike 5525 to 5545. 160 to 162: Refit oxygen because bottom of profile was too high (.04ml/l). 160 Interpolate over salt spike 4415 to 4433db. 161 Interpolate over salt spikes 2307 to 2323 and 4359 to 4361db. 162 Interpolate over salt spike 2357 to 2365db. 163 Interpolate over salt spikes 2363 to 2375 and 4327 to 4339db. 164 Gap in data, 4565 to 4603 dbar.

The log details the major difficulties experienced on P06. In general, operations on stations not discussed below went more-or-less normally. CTD instrument and station numbers: CTD 10 Stations LEG 3: 1,4-72 LEG 4: 74,75,86-111,113-140 142-186,188 LEG 5: 190-212 CTD 9 Stations LEG 3: 3 LEG 4: 76-85,112,141,187 LEG 5: 189 CTD 7 Stations LEG 3: 2 LEG 4: 73 LEG 5: CTD 10 was the primary instrument on the cruise, #9 was called into service for some 10 stations during leg 3 when #10 failed. CTD #9also failed on that leg, but by that time CTD #10 had been repaired. CTDs 9 and 10 were equipped with a second temperature channel(using an FSI Ocean Temperature Module). Data from these sensors were used to assess when during the cruise shifts in the primary temperature sensor occurred. CTD #10 was also equipped with a pump, designed to make uniform the flow of seawater past the dissolved oxygen sensor. The oxygen pump was used throughout leg 3. Careful examination of the Leg 3 data after the cruise suggested the pump did not function as well as was hoped (or tested on earlier expeditions). The oxygen current data are quite noisy in the top several hundred meters from Leg 3.(Possibly the pump was cavatating on air not bled from the supply tube.)In any event, the final P06 data from Leg 3 have quite noisy oxygens in the upper ocean. Users may wish to do some vertical averaging/filtering prior to using these data. The oxygen pump was removed from the system at the start of Leg 4 and not used for the rest of the expedition.
