The cruise commenced with work around the former Mertz Glacier ice tongue, followed by a south to north occupation of the CLIVAR/WOCE meridional section I9S (Figure 1). Five oceanographic moorings were recovered from the southern end of I9S. Some bottom imaging camera work was conducted during the Antarctic phase, as part of the ongoing CEAMARC biological program. This report discusses the oceanographic data from CTD operations on the cruise. The primary project was a reoccupation of the I9S transect, previously occupied by the RV Knorr in 1995 (P.I. Mike McCartney, WHOI), and by the Aurora Australis in 2004/05 (Rosenberg et al., unpublished). The primary oceanographic aims of this project are: * to measure changes in water mass properties and inventories throughout the full ocean depth between Australia and Antarctica along 115E; * to estimate the transport of mass, heat and other properties south of Australia, and to compare the results to previous occupations of the I9S line and other sections in the Australian sector; * to identify mechanisms responsible for variability in ocean climate south of Australia; * to use repeat measurements to assess the skill of ocean and coupled models. The recovered moorings were deployed two years previously as part of a joint US/Australian project to measure westward recirculation in the subpolar gyre of the southeastern Indian Ocean. Mooring data are to be processed by WHOI, and are not discussed further in this report. The third oceanographic project was opportunistic, taking CTD measurements in the region formerly occupied by the Mertz glacier tongue (Rosenberg and Rintoul, unpublished). Note that CTD station 2 was at the site occupied by Sir Douglas Mawson in 1911. A total of 95 CTD vertical profile stations were taken on the cruise, most to within 15 metres of the bottom (Table 1). Over 1500 Niskin bottle water samples were collected for the measurement (Table 2) of salinity, dissolved oxygen, nutrients (phosphate, nitrate+nitrite and silicate), dissolved inorganic carbon (i.e. TCO2), alkalinity, pH, barium (dissolved), and biological parameters, using a 24 bottle rosette sampler. Full depth current profiles were collected by an LADCP attached to the CTD package, while upper water column current profile data were collected by a ship mounted ADCP. Meteorological and water property data were collected by the array of ship's underway sensors. An array of 5 current meter moorings was recovered from the Antarctic continental slope at the south end of the I9S transect. This report describes the processing/calibration of the CTD data, and details the data quality. Underway sea surface temperature and salinity data are compared to near surface CTD data. CTD station positions are shown in Figure 1, while CTD station information is summarised in Table 1. Argo float deployments are summarised in Table 13. Further cruise itinerary/summary details can be found in the voyage leader report (Australian Antarctic Division unpublished report: Rintoul, Voyage 3, 2011- 2012, RSV Aurora Australis, Voyage Leader’s report). 2 CTD INSTRUMENTATION SeaBird SBE9plus CTD serial 704, with dual temperature and conductivity sensors and a single SBE43 dissolved oxygen sensor (serial 0178, on the primary sensor pump line), was used, mounted on a SeaBird 24 bottle rosette frame, together with a SBE32 24 position pylon and up to 22 x 10 litre General Oceanics Niskin bottles. The following additional sensors/instruments were mounted: * Wetlabs ECO-AFL/FL fluorometer serial 296 * Biospherical Instruments PAR sensor QCP2300HP, serial 70110 * Wetlabs C-star transmissometer serial 1421DR * Teledyne RDI lowered ADCP (i.e. LADCP) workhorse monitor – 300 kHz upward looking head; 150 kHz downward looking head; battery housing * Aanderaa optode serial 576 (stations 1 to 82) * Tritech 500 kHz altimeter serial 126288 (stations 1 to 91) * Tritech 500 kHz altimeter serial 76031 (stations 92 to 95) * Tritech 200 kHz altimeter serial 237622 (stations 1 to 74 and 76 to 79) * Tritech 200 kHz altimeter serial 126287 (station 75 and 80) (didn’t work) * Tritech 200 kHz altimeter serial 126376 (station 81) (didn’t work) * Tritech 200 kHz altimeter serial 237621 (stations 82 to 95) * camera system and strobe lighting (stations 2 to 15 and 90 to 95) CTD data were transmitted up a 6 mm seacable to a SBE11plusV2 deck unit, at a rate of 24 Hz, and data were logged simultaneously on 2 PC's using SeaBird data acquisition software "Seasave" version 7. The CTD deployment method was as follows: * CTD initially deployed down to ~10 to 20 m * after confirmation of pump operation, CTD returned up to just below the surface (depth dependent on sea state) * after returning to just below the surface, downcast proper commenced For most casts the package was stopped on the upcast at ~50 m above the bottom, for collection of bottom track data by the LADCP. When the camera system was fitted the package was stopped for several minutes within 5 m of the bottom. Pre cruise temperature, conductivity and pressure calibrations were performed by SeaBird (Table 3) (June 2011). The SeaBird calibration for the SBE43 oxygen sensor was used for initial data display only. Manufacturer supplied calibrations were used for the fluorometer, transmissometer, PAR and altimeter. Final conductivity and dissolved oxygen calibrations derived from in situ Niskin bottle samples are listed later in the report. Final transmissometer data are referenced to a clean water value (see section 5.5 below). For the optode phase and temperature, slope/offset corrections were applied to the raw voltages (corrections supplied by Craig Neill, CSIRO). 3 PROBLEMS ENCOUNTERED CTD operations went relatively smoothly, with fewer equipment/gear problems than on the previous cruise. The most significant gear issue was the high loads experienced by the 6 mm sea cable during the deep CTD casts. High loads on the 6 mm cable have always been a concern in the past, but on this occasion there was a load cell to measure them (data not discussed in this report). Large remnants of the B9B iceberg were still present in the Mertz region, but access to Commonwealth Bay remained straightforward. The time available for the CTD work there was less than hoped for, due to time commitments for the official Mawson’s Hut visit, and only 6 shallow CTD’s were completed in the area. Other notable problems were as follows: * Two hours were lost at station 3, due to CTD gantry problems. * Nearly a day was lost at station 35, at first due to bad weather, then later awaiting completion of servicing to the ship’s generators. * The seacable was reterminated prior to stations 28 and 40, due to kinking of the wire. * About halfway through the cruise the tension control procedure by winch operators during bottom approach was changed. The CTD package touched bottom on two occasions as a result (at stations 57 and 71). A further problem occurred during the upcast at station 57, with an unexplained CTD comms crash. Comms were successfully re-established after power cycling the CTD deck unit. * CTD comms failed near the end of the upcast at station 63, and the last 2 rosette positions were not fired. The electrical termination had failed, requiring another retermination. * CTD comms crashed during station 82 just after commencement of the upcast, with inability to fire bottles and no data for the upcast. Flooding of the optode was the cause, an identical experience to the previous cruise. After removing the optode the station was repeated. * At station 89, the package touched bottom for a third time, due to steep bathymetry and unstable altimeter readings. * The 200 kHz altimeter started to fail during station 73. The problem turned out to be a failing y-cable. All the altimeters were tested over the remainder of the cruise, revealing two bad instruments: serials 126287 and 126376 (both 200 kHz). A third instrument (serial 126288, 500 kHz) failed near the end of the cruise. 4 CTD DATA PROCESSING AND CALIBRATION Preliminary CTD data processing was done at sea, to confirm correct functioning of instrumentation. Final processing of the data was done in Hobart. The first processing step is application of a suite of the SeaBird "Seasoft" processing programs to the raw data, in order to: * convert raw data signals to engineering units * remove the surface pressure offset for each station * realign the oxygen sensor with respect to time (note that conductivity sensor alignment is done by the deck unit at the time of data logging) * remove conductivity cell thermal mass effects * apply a low pass filter to the pressure data * flag pressure reversals * search for bad data (e.g. due to sensor fouling etc) Further processing and data calibration were done in a UNIX environment, using a suite of fortran and matlab programs. Processing steps here include: * forming upcast burst CTD data for calibration against bottle data, where each upcast burst is the average of 10 seconds of data centered on each Niskin bottle firing * merging bottle and CTD data, and deriving CTD conductivity calibration coefficients by comparing upcast CTD burst average conductivity data with calculated equivalent bottle sample conductivities * forming pressure monotonically increasing data, and from there calculating 2 dbar averaged downcast CTD data * calculating calibrated 2 dbar averaged salinity from the 2 dbar pressure, temperature and conductivity values * deriving CTD dissolved oxygen calibration coefficients by comparing bottle sample dissolved oxygen values (collected on the upcast) with CTD dissolved oxygen values from the equivalent 2 dbar downcast pressures Full details of the data calibration and processing methods are given in Rosenberg et al. (unpublished) , referred to hereafter as the CTD methodology. Additional processing steps are discussed below in the results section. For calibration of the CTD oxygen data, whole profile fits were used for shallower stations, while split profile fits were used for deeper stations. Final station header information, including station positions at the start, bottom and end of each CTD cast, were obtained from underway data for the cruise (see section 6 below). Note the following for the station header information: * All times are UTC. * "Start of cast" information is at the commencement of the downcast proper, as described above. * "Bottom of cast" information is at the maximum pressure value. * "End of cast" information is when the CTD leaves the water at the end of the cast, as indicated by a drop in salinity values. * All bottom depth values are corrected for local sound speed, where sound speed values are calculated from the CTD data at each station. * "Bottom of cast" depths are calculated from CTD maximum pressure (converted to depth) and altimeter values at the bottom of the casts. Lastly, data were converted to MATLAB format, and final data quality checking was done within MATLAB. 5 CTD AND BOTTLE DATA RESULTS AND DATA QUALITY Data from the primary CTD sensor pair (temperature and conductivity) were used for the whole cruise. Suspect CTD 2 dbar averages are listed in Table 9, while suspect dissolved oxygen bottle samples are listed in Table 11. Nutrient and dissolved oxygen comparisons to previous cruises are made in section 7. 5.1 Conductivity/salinity The conductivity calibration and equivalent salinity results for the cruise are plotted in Figures 2 and 3, and the derived conductivity calibration coefficients are listed in Tables 4 and 5. Station groupings used for the calibration are included in Table 4. International standard seawater batch number P153 (8th March 2011) was used for salinometer standardisations. Guildline Autosal serial 62549 was used for the whole cruise, with analyses taking place in lab 5 (usually a refrigerator lab). Salinometer performance was stable, with lab temperature ranging mostly between ~20 and 21.5oC over the course of the cruise (mean lab temperature=20.70oC, standard deviation 0.37oC). Overall salinity accuracy for the cruise is within 0.002 (PSS78). For the previous cruise au1121 (Rosenberg and Rintoul, unpublished), increased scatter in salinity residuals (i.e. bottle salinity – calibrated salinity) was found for southern stations in the region of the former Mertz Glacier, with the scatter attributed to biological activity and/or cold water effects. Equivalent samples for this cruise (stations 2 to 7) did not show the same large scatter. Conductivity calibrations for these stations were good, with residual scatter only evident for shallower samples in steep vertical gradients. Pressure dependent salinity residuals are evident for most cruises (Rosenberg and Rintoul, unpublished). For this cruise the residuals, where they occurred, were of the order 0.002 (PSS78) or less over the whole vertical profile. The largest pressure dependent residual was ~0.003 (PSS78) for station 36 (Figure 4). Note from the figure that for many other stations no consistent pressure dependency is evident, and the residual scatter is within calibration accuracy. Also note that where the pressure dependency occurred, the magnitude over the whole profile was often larger for the secondary sensor data (not shown here). Close inspection of the vertical profiles of the bottle-CTD salinity difference values reveals a slight biasing for a few stations, mostly of the order 0.001 (PSS78), as follows: station bottle-CTD bias (PSS78) ---------- ----------------------- 25, 33 -0.001 47, 48, 70 -0.0005 60 +0.001 This is most likely due to a combination of factors, including salinometer performance. There is no significant diminishing of overall CTD salinity accuracy from this apparent biasing. Bad salinity bottle samples (not deleted from the data files) are listed in Table 10. 5.2 Temperature Temperature differences between the primary and secondary CTD temperature sensors (Tp and Ts respectively), from data at Niskin bottle stops, are shown in Figure 5. The difference Ts – Tp is within the manufacturer quoted sensor accuracy of 0.001oC. Note from the figure that Ts – Tp moves closer to 0, either in colder water or at shallower pressures (difficult to separate the two dependencies). 5.3 Pressure Surface pressure offsets for each cast (Table 6) were obtained from inspection of the data before the package entered the water. Pressure spiking, a problem on some previous cruises, did not occur, other than during comms problems at stations 57, 63 and 82. For station 83, the first station after a system crash caused by a leaking optode, the surface pressure offset value was noticeably different to the values from surrounding stations (no explanation). 5.4 Dissolved oxygen CTD oxygen data were calibrated as per the CTD methodology, with profiles deeper than 1400 dbar calibrated as split profile fits, and profiles shallower than 1400 dbar (i.e. stations 2 to 7, 9, and 91 to 95) calibrated as whole profile fits. The exceptions were for station 1 (a test cast to ~2900 dbar) and station 12 (a cast to ~1480 dbar), where whole profile fits were used to improve the calibration results. For the following stations, no bottle samples were collected, therefore CTD oxygen data were not calibrated: 8, 10, 13, 16, 19, 22, 26, 37, 55, 56, 61, 62, 65, 71, 74, 76, 77, 82 and 84. Calibration results are plotted in Figure 6, and the derived calibration coefficients are listed in Table 7. Overall the calibrated CTD oxygen agrees with the bottle data to well within 1% of full scale (where full scale is ~420 μmol/l above 1500 dbar, and ~250 μmol/l below 1500 dbar). * Bottle overlaps between the shallow and deep fits were varied slightly for the following stations: 11, 14, 15, 45 and 90. * For station 2, the top section of the oxygen profile was unusable due to missing near surface bottle data. * For station 6, the lower part of the profile has been flagged as suspect due to a missing bottom bottle sample. * For station 35, the whole profile calibration result was slightly better than the split profile result, but the split profile result has been retained. * For station 83, bad CTD oxygen data from ~50 to 100 dbar have been removed. * Bubbles in reagent 2 dispenser caused a few bad oxygen samples. 5.5 Fluorescence, PAR, transmittance, altimeter, optode All fluorescence, PAR and transmittance data have a manufacturer supplied calibration (Table 3) applied to the data, with transmittance values referenced to clean water. In the CTD 2dbar averaged data files, both downcast and upcast data are supplied for these sensors; and the data are strictly 2 dbar averages (as distinct from other calculations used in previous cruises i.e. au0703, au0803 and au0806). Fluorescence spikiness was caused by interference from the camera strobe lights, mounted on the CTD package and operating for stations 2 to 15 and 90 to 95. Initially, the SeaBird “filter” program (with a low pass filter value of 1 sec) was used to attempt to smooth the spikes. Some undesirable artefacts were caused by the filtering, and the final fluorescence data were left unfiltered. In general, obvious bad data spikes from deeper water are easily removed. In shallower water however, where the real fluorescence signal occurs, it’s very difficult to separate any erroneous data spiking from the real fluorescence signal. The PAR calibration coefficients in Table 3 were calculated from the manufacturer supplied calibration sheet, using the method described in the following SeaBird documents: page 53 of SeaSave Version 7.2 manual; Application Note No. 11 General; and Application Note No. 11 QSP-L. The PAR calibration “offset” value (Table 3) was derived from deep water voltage values from the previous cruise au1121. Transmittance data appear reasonable qualitatively, though there’s some hysteresis between the down and upcast data, for station 48 onwards, mainly in the top ~1000 dbar. Quantitatively, deck tests indicated the transmissometer calibration was out, with full scale readings of 5 V in air, and dark voltage readings of ~1.2 V (simulated by covering the sensor by hand). Note that station 1 downcast data are suspect for the top ~200 dbar, with transmittance values exceeding 100%, and appearing significantly different to the upcast. The usual altimeter “artefacts”, as seen on previous cruises (described in Rosenberg and Rintoul, unpublished), were observed on both the 200 and 500 kHz Tritech sensors, with false bottom readings often observed before coming within nominal altimeter range. For station 75 onwards, the altimeters were frequently swapped to confirm performance of all 6 units. For optode data (stations 1 to 82), the following linear calibrations (Craig Neill, CSIRO CMAR) have been applied to the raw voltage data: optode phase = volts x 12 + 10 optode temperature = volts x 9 - 5 The optode flooded during station 82, as described earlier, and no optode was fitted for station 83 onwards. Note that the optode was fitted for comparison purposes, and only the SBE43 oxygen data should be used in any data analyses. 5.6 Nutrients Nutrients measured on the cruise were phosphate, total nitrate (i.e. nitrate+nitrite), and silicate, using a Lachat autoanalyser. Most values are an average of twin analyses (done at the time of each sample analysis). Much pre-screening of the nutrient data (including the twin analyses and repeat runs) was done by the hydrochemists, and as a result there are no obviously suspect data flagged in the final data set. Note that full scale for phosphate, nitrate and silicate are respectively 3.0 μmol/l, 35 μmol/l, and 140 μmol/l. Nitrate+nitrite versus phosphate data are shown in Figure 7. For stations 2 to 7 (from the Mertz region), the data follows a different trend to the remainder of the cruise, and this appears to be a real feature. * There are no phosphate data for stations 33, 43 and 68, due to analysis problems. Further assessment of nutrient data quality is given in section 7 below, comparing the data to previous cruises. Additional nutrient analysis notes from the hydrochemists: Bad data * Station 33, phosphate – RMNS and bulk QC significantly lower than expected - data rejected. * Station 43, phosphate – fresh sample analysis and repeat sample analysis both bad – data rejected. * Station 68, phosphate – fresh sample analysis and repeat sample analyses all bad – data rejected. Cautions * Stations 45, 48 and 50, nitrate – frozen for 6 months and analysed in Hobart. For station 50, the samples were labelled “already thawed and refrozen during voyage”. * Stations 66 and 67, nitrate – from frozen samples, but analysed during the voyage not long after sampling. * Station 68, nitrate – combined results from frozen samples from during the voyage and from 6 months after the voyage – all within tolerance. * Station 79, nitrate – the only nitrate run with a suspect calibration; QC and RMNS data show the results are okay. * Station 34, phosphate – frozen samples analysed during the voyage; single dip analysis. * Station 69, phosphate – samples frozen for 6 months; phosphate issue^^ * Station 87, all nutrients – an instrument error stopped the run (close to the end of the run); final calibration stitched together; calibration and QC data look good. * Stations 89, 90 and 91, phosphate – samples frozen for 6 months; phosphate issue^^ * Stations 92 to 95, phosphate – merged from 2 different runs (fresh samples during the voyage, and samples frozen for 6 months). Merged data matches well. phosphate issue^^ ^^phosphate issue: for autoanalyser runs 77 onwards (i.e. stations 89 to 95 plus some repeats), there was a significant increase in the expected QC. The calculated concentration of calibrants consistently decreased at this point. Issue currently unresolved. 5.7 Additional CTD data processing/quality notes * Station 34 – problem with secondary sensors for bottles 18 to 24 i.e. top ~110 dbar of upcast. * Station 44 – bottle 21 was tripped on the fly. * The package touched bottom at stations 57, 71 and 89. In all 3 cases disturbance of the bottom sediment is evident from the transmittance data. No sensors were damaged or calibrations shifted as a result of the contacts; and there has been no despiking of any sensor data affected by the disturbed sediment (e.g. bottom 2 dbar salinity bin for station 71). * Station 63 – the rosette was only fired 20 times before the comms crash, and data collection ended at ~45 dbar on the upcast. * Station 82 - bad data near the bottom (due to optode failure) have been removed. * For the XBT yoyo casts (55, 56, 61, 62, 76, 77), depth at the bottom of the cast is from the full depth cast at each of the sites. 6 UNDERWAY MEASUREMENTS Underway data were logged to an Oracle database on the ship. Quality control for the cruise was largely automated. 12 kHz bathymetry data were quality controlled on the cruise (Graham Campton, Ric Frey, Anthony Moxham and David Sowter, Royal Australian Navy Hydrographic Office). 1 minute instantaneous underway data are contained in the file au1203.ora as column formatted text; and in the file au1203ora.mat as matlab format. Data from the hull mounted underway temperature sensor (Tdls) and the underway thermosalinograph salinity (Sdls) are compared to CTD temperature and salinity data at 8 dbar (Figures 8 and 9). For temperature (Figure 9a), the agreement is reasonably close down to 5oC; below this the Tdls-TCTD difference trends up towards ~0.02 at the lowest temperature values. For salinity (Figure 9b), there’s a reasonable amount of scatter, and the bestfit line should not be relied on; overall, the Sdls-SCTD difference for the cruise can be estimated at ~-0.06 (PSS78). Note that these comparisons have not been applied to the underway data. 7 INTERCRUISE COMPARISONS Intercruise comparisons of nutrient and dissolved oxygen data on neutral density (i.e. _) surfaces are shown in bulk plots, comparing au1203 and au0403 (Figure 10a), and au1203 and i8si9s (1994-95 RV Knorr cruise, P.I. Mike McCartney, CCHDO expocode 316N145_5) (Figure 10b). Note that all au1203 and au0403 nutrient and dissolved oxygen data have been converted here to μmol/kg units (to match the Knorr data). Bulk plots of all the difference data are shown against latitude in Figure 11 (au1203- au0403) and Figure 12 (au1203–i8si9s). Taking averages of the data in Figures 11 and 12, the comparisons can be quantified as follows: phosphate au1203 > au0403 by 0.05 au1203 > i8si9s by 0.03 nitrate au1203 > au0403 by 0.3 au1203 > i8si9s by 0.3 silicate au1203 > au0403 by 1.8 au1203 > i8si9s by 1.5 dissolved oxygen bottle data au1203 > au0403 by 0.4 au1203 > i8si9s by 0.2 Closer inspection of the data reveals some variation with latitude, in particular for phosphate and nitrate in the au1203-i8si9s comparison (Figure 12). In both cases there’s a shift in the difference values south of ~42oS. Note that this is not necessarily a latitude dependence – rather, it may be related to sample analysis during the cruises. The intercruise variability for bottle oxygen data are within 1% of full scale. For the nutrient data, the differences are within 1% of full scale for nitrate and just over 1% of full scale for silicate. For phosphates, a clear offset close to 2% of full scale is evident from the au1203-au0403 comparison, most likely due to variation in autoanalyser performance (specific reasons unknown). Phosphate results have previously shown significant intercruise offsets (Rosenberg and Rintoul, unpublished). 8 FILE FORMATS Data are supplied as column formatted text files, or as matlab files, with all details fully described in the README file included with the data set. Note that all dissolved oxygen and nutrient data in these file versions are in units of μmol/l. The data are also available in WOCE “Exchange” format files. In these file versions, dissolved oxygen and nutrient data are in units of μmol/kg. For density calculation in the volumetric to gravimetric units conversion, the following were used: dissolved oxygen – in situ temperature and CTD salinity at which each Niskin bottle was fired; zero pressure nutrients – laboratory temperature (22.0oC), and in situ CTD salinity at which each Niskin bottle was fired; zero pressure REFERENCES Rosenberg, M., Fukamachi, Y., Rintoul, S., Church, J., Curran, C., Helmond, I., Miller, K., McLaughlan, D., Berry, K., Johnston, N. and Richman, J., unpublished.
