Narrative This expedition was conducting operations in support of three ongoing scientific initiatives. The first initiative is in support of the North Atlantic Oscillation and the Atlantic Thermohaline Circulation Principal Research Areas of the Climate Variability and Predictability (CLIVAR) project of the World Climate Research Programme (WCRP). The occupation of the Labrador Sea section and the recovery of the two Labrador Sea moorings provide a measure of the winter cooling and water mass transformations over the winters of 2000/2001. The resetting of the mooring on the 1000 metre isobath on the Labrador slope continues a 20+ year observation program of the Labrador Current. The second initiative is the Labrador Sea project of the Canadian Joint Global Ocean Flux Study (JGOFS). The biological program is designed to characterize the late spring biological processes in the Labrador Sea and its shelf regions and is discussed in a later section of this document. The physical/chemical oceanographic program observes nutrients, total carbonate, alkalinity and CFCs over the entire water column in order to document the vertical transport of carbon via winter convection in the Labrador Sea as well as the changes in carbon storage in the deep waters of the North Atlantic. The third objective is to observe the physical and chemical parameters at the various stations of the Halifax Section in support of DFO's Atlantic Zonal Monitoring Program. In addition, the Moving Vessel Profiler (MVP) is to be deployed on an opportunity basis while the vessel is transiting between BIO and the Labrador Sea. These sections of opportunity will be observed to provide detailed estimates of the spatial structures of the Scotian shelf, Gulf of Saint Lawrence and Cabot Strait. The fourth objective is to recover and set moorings on the continental slope at the end of the Halifax Section. These moorings are designed to provide information on the structure of the current field to provide information related to the exploration and exploitation of oil and gas under the deeper areas of the continental slope. b. Processing of the measurements collected with the Moving Vehicle Profiler (MVP) (Igor Yashayaev) Original MVP data files - The MVP acquisition software stores profile measurements and engineering data in nine ASCII files. These file sets are named evtXXX.YYY#, where XXX is the event number, YYY - a three- digit profile name, and # can be one of eight letters (a, c, d, e, g, h, s, t) or omitted. In the last case (the naming of the MVP files is reduced to evtXXX.YYY), the files contain the header information (PC- Time, PC-Date, GPS strings with position and time, bottom depth and ship speed) and unprocessed (raw MVP) measurements of pressure, conductivity and temperature at the original sampling rate of 25 Hertz. MVP to CNV conversion - The Seabird processing software (hereafter Seasoft) represents a multifunctional and comprehensive processing system, providing complete processing capabilities of CTD data from the raw to final datasets. This motivated us to develop a utility for conversion of a raw MVP data file to a cnv file, which is the generic file format of the Seasoft. Another motivation for such conversion is in the popularity of Seabird CTD: many applications which are used with the cnv files will be applicable to MVP data. A utility was produced, mvp2cnv, to convert a raw MVP data file (evtXXX.YYY) to a cnv file (XXX_YYY.cnv). The utility adds a header containing instrument, time and position information, data description (these form a header) and raw data obtained from the original file. The raw data (scan, pressure, temperature, conductivity and flag) are stored in XXX_YYY.cnv in a Seasoft specific format (all integer and floating point values must be 11 bytes long - this is important for operation of the Seasoft modules). mvp2cnv finds the header template from a file named mvp.hdr, inheriting the structure of the Seasoft header. This header file can be edited (cruise information, chief scientist, comments, etc.). The brackets '<' and '>' in the header template indicate a position where the corresponding information (time, position, etc.) will be filled in by mvp2cnv. To perform the conversion enter mvp2cnv evtXXX.YYY, or run a batch file listing mvp2cnv evtXXX.YYY lines with different XXX and YYY. Finding the time advance for MVP temperature - Due to the difference in time response of pressure, temperature and conductivity sensors the corresponding measurements need to be filtered and aligned in time prior to use in analyses and computations (of salinity, density, sound velocity etc.). To determine the filtering options and the relative time advance of temperature and conductivity that provide the most consistent temperature-salinity-density-pressure data set, we developed a utility (alignmvp) to test the statistical and physical properties of observed and computed variables. These tests were conducted for each T vs. C time advance. The various advances control: (1) the level of noise and spikiness in salinity and density, (2) the number and magnitude of density inversion, (3) the differences between downtrace and uptrace profiles and (4) the correlation between temperature and conductivity series. The tests are being conducted for uptrace and downtrace separately (except 3) and summary of the tests stored in files: al*.cnv and alignmvp.sum. To test different offsets of temperature measurements enter alignmvp evtXXX.YYY. Processing of converted MVP files with Seabird Software - Once the MVP data were converted to Seabird file format, they could be processed with the Seasoft modules. A simple processing deck includes: - to exclude obvious outliers in temperature and conductivity, - to advance temperature and conductivity readings, - to low-pass filter pressure, temperature and conductivity, - to calculate salinity, potential temperature and density, - to bin average data in time bins, - to separate down and uptrace profiles and - to convert processed cnv files to odf. Preliminary XBT Data - A preliminary plot of the XBT data is shown in Figure 3. See also section B.4 of this report. Figure 3. Section plot of preliminary XBT data along AR7W. 4.2 Biological Program a. Narrative The biological program conducted as part of cruise 2001022, with some modifications, was a continuation of studies began in 1994 to describe the large-scale (spatial and temporal) variability in plankton biomass, productivity and biogenic carbon inventories in the Labrador Sea. The program has consisted of essentially five elements: • a phytoplankton biomass/primary productivity program - conducted Glen Harrison and Brian Irwin (this year including Gary Maillet and Gadiel Alarcon), • a microbial program conducted by Bill Li and Paul Dickie, • a mesozooplankton program conducted by Les Harris (for Erica Head), • a dissolved organic carbon/community respiration program conducted by Jay Bugden (for Paul Kepkay), and • a sediment trap program conducted by Glen Harrison and Brian Irwin. The ultimate aim of these studies is twofold: • to provide a description of the inventories in and export of biogenic carbon from the Labrador Sea, their turnover rates and variability in space and time as part of OSD's continuing climate-studies and • to provide a description of plankton life-cycles and productivity in the Labrador Sea and its influence or contribution to ecosystems downstream in support of OSD's fisheries-related research. In addition to the Labrador Sea study, phytoplankton, mesozooplankton and nutrient samples were collected at the seven stations along the Halifax line in support of OSD's obligations to the Atlantic Zone Monitoring Program (AZMP). b. Stable Isotope Studies of Carbon and Nitrogen (nitrate and ammonium) Utili-zation by Phytoplankton (Glen Harrison) This work represents a continuation of research begun in 1994 to determine the primary productivity (in terms of carbon and nitrogen) of phytoplankton in the Labrador Sea. Carbon dioxide (CO2), nitrate (NO3) and ammonium (NH4) utilization rates from eight depths in the photic zone (i.e. the 1% light level ranged from 30-50 m) were determined using stable isotope tracer (13C and 15N) methods. Incubations experiments were carried out in on-deck 'simulated in-situ' incubators. At a few stations, 14C incubations were done in parallel for comparison. A total of 13 experiments were conducted (see Table 6); 9 stations were occupied in the Labrador Sea, one in the NE Gulf of St Lawrence and one on the Scotian Shelf. Carbon and nitrogen-based primary productivity rates at these locations will be related to vertical fluxes of particulate biogenic carbon and nitrogen derived from our sediment trap deployed at 1,053 m on the "Bravo" mooring (M1349) during this the 2000-009 mission and recovered on this mission. In addition to productivity measurements, samples from two deep casts were collected for determination of particulate organic carbon (POC) and nitrogen (PON) and NH4 to ~2,000 m. Table 6.

Zooplankton Sampling (L. Harris) The zooplankton sampling is part of an ongoing program, the aim of which is to investigate the distribution, abundance and life history of the major zooplankton groups found in the Labrador Sea and its associated shelf systems. Particular emphasis is placed on the copepod species of the Calanus genus, which dominate the zooplankton in this region. Vertical net tows (Figure 4) were taken at 47 stations (9 on or near the Scotian Shelf, 1 in the Gulf and 37 from the Labrador Shelf/Labrador Sea) using a 3/4 metre 200 (m mesh ring net. At all stations, tows were made from 100 meters to the surface. Additional deep tows (2500 meters to the surface) were taken at 4 of the stations in the Labrador Sea. Samples will be analysed for species composition, copepod stage structure and biomass. Nine additional tows using a 30 cm 75 (m net were made. Figure 4. Net tow and multinet tow locations for 18HU2001022_1. d. Measurements Of Copepod Reproduction Rates (L. Harris) Egg production rates of Calanus finmarchicus, the dominant copepod species, were measured at 14 stations (3 on the Scotian Shelf, 1 in the Gulf and 10 from the Labrador Shelf/Labrador Sea). e. Total Organic Carbon (TOC) and Microbial Community Respiration (Jay Bugden and Paul Kepkay) In order to better understand the cycling of carbon and the mechanisms controlling it in the Labrador Sea, it is necessary to examine the pool of total organic carbon (TOC), and look at the activity of the microbial community in the water column. By examining the rate of respiration and size fractionating the TOC, information on the fate of carbon in this marine environment may be elucidated. During CCGS Hudson cruise 2001-022 eight (8) stations were sampled at a 10m and 40m depth, for gross microbial community respiration, and at 10m only ultrafiltrations were performed for size fractionation of TOC. The stations sampled are listed below. TOC depth profiles were also collected from all twenty-eight (28) stations listed below. Table 7 lists the stations and what was sampled on CCGS Hudson cruise 2001-022. BRAVO is a mooring site located near the AR7W line. SLC is a biological station located between Line 3 (AR7W) and Line 4 at 54o 41.57N 52o 30.04W, operation ID number 238. Table 7. Ultrafiltration, respiration and TOC sample collection.

Primary Production Measurements (Brian Irwin) Water samples for primary production experiments were collected from the rosette at fourteen (14) stations (see Table 8). Depths sampled were 10, 20 and 40m. For each sample, 33 aliquots were innoculated with sodium bicarbonate 14C and then incubated at in situ temperatures at 30 light levels ( 3 were dark bottles) for 2 to 3 hours. At the end of the incubation period the cells were harvested onto GF/F glass fibre filters for later counting in a scintillation counter. For each sample, three chlorophylls, three particulate carbons, one HPLC, one Absorption Spectra, one Dissolved Organic Carbon and one nutrient aliquot were collected and stored frozen for later analysis. f. Primary Production Studies Using 14C (Gary Maillet) Measurement of primary production was conducted during Hudson Cruise 2001-022 using the radioisotope carbon-14 technique. Measurement of photosynthesis - irradiance experiments were conducted using two custom- built photosynthetrons. Primary production measurements were confined to the upper water column. Seawater samples were obtained from the CTD- rosette Niskin bottles at 10-40m depths and from a submersible pump (4m) at designated biological sampling stations (Table 9). Measurement of carbon-14 uptake experiments will be used to compute photosynthetic parameters and to estimate daily integrated production over the euphotic zone across the Labrador Sea transect. Results will also be compared with Glen Harrison and Brian Irwin's incubations to determine general applicability of photosynthetron system for estimation of photosynthetic parameters. Due to the unavailability of a scintillation counter aboard the Hudson, these results could not be completed prior to completion of the cruise. g. Abundance and Production of Microbial Plankton (William Li and Paul Dickie) The abundance of phytoplankton was measured by shipboard flow cytometric analysis of single cells characterized by properties of light scatter and pigment fluorescence, using methods previously published (Li 1995. Marine Ecology Progress Series). A total of 334 samples were analyzed (see Table 10). The abundance of bacterioplankton will be measured at a later date by flow cytometric analysis of samples cryogenically preserved in paraformaldehyde, using methods previously published (Li et al. 1995. Limnology and Oceanography). A toal of 834 samples were collected for this purpose. Table 8. Sampling for primary production.

Marine Microbial Food Webs). A total of 182 samples were assayed on board ship. The abundance of heterotrophic nanozooplankton will be estimated at a later date by epifluorescence microscopy of DAPI-stained cells collected by gentle vacuum filtration and mounted on microscope slides, according to the protocols of Gifford and Caron (2000. ICES Zooplankton Methodlogy manual). A total of 19 samples were collected for this purpose. Table 10. Sampling for microbial plankton.

182 19 h. Mooring Sediment Traps (Glen Harrison and Brian Irwin) Two sediment traps were deployed at the "BRAVO" mooring (at 175 m and 1,053 m) during the 2000-009 mission. The trap design employed was developed at BIO (Bioflux traps), has a 24-cup capacity and internal Tattletale computer for programming particle collection intervals. Cups were programmed to collect material for two-week intervals starting 12:01AM (GMT), 01 June, 2000. Due to a failure in the mooring line, only one (1,053 m) trap was recovered during the 2001-022 mission. The trap was recovered upright and based on preliminary inspection of the sampling cups, the deployment appeared to be successful as evidenced by significant biological material presence in all 24 cups. Analysis of the pressure record from the Seacat immediately below the trap indicated that the trap collected material at the nominal deployment depth for the first 88 days. Then, the trap was displaced some 1,300 m deeper at the time of the mooring line failure where it remained for the rest of the deployment. Judging from the nature and quantity of collected material, it appears that major vertical particulate transport occurred during the fall and early winter of 2000 and virtually no transport occurred in spring 2001. The samples will be processed back at BIO for particulate and dissolved biogenic (organic) carbon and nitrogen content as well as other constituents. These particle fluxes will provide the first direct estimates of seasonal variability and annual magnitude of the "Biological Pump" and its contribution to carbon sequestering in the region. h. Methyl Halides and Chlorinated Compounds (R.M. Moore, S. Punshon and R. Tokarczyk) Measurements were made in seawater samples for methyl halides and a suite of chlorinated compounds that have short atmospheric lifetimes. These include dichloromethane, chloroform, trichloroethylene and tetrachloroethylene (also referred to as perchloroethylene or PCE). The objective of these measurements is to quantify the relative magnitudes of anthropogenic and marine sources of these compounds and to identify potential tracer applications. Water samples were analyzed by purge- and-trap and gas chromatography-mass spectrometry. Preliminary results indicate good results for most of the compounds, but difficulties were experienced with PCE almost certainly as a result of its occasional use on the vessel as a cleaning or degreasing agent. On L4 7 profiles were analyzed in addition to 3 taken earlier - casts 34, 39 and 44. A small number of air samples were collected in canisters and analyzed on board for the same compounds. The site number or operation number of sampled locations are given in Table 11. The locations are shown in Figure 5. Potential production rates of nitrous oxide (N2O) resulting from nitrification and denitrification were measured using stable isotope techniques to assess the relative importance of these processes in the upper water column of the Labrador Sea. N2O depth profiles down to 100m were measured at nine of the shallow biological stations. At six of these stations, samples from three depths, typically 20, 60, and 100m were incubated in glass syringes with added 15-N ammonium and nitrate. Time-series measurements of 15-N labelled nitrous oxide concentration within these samples were made using a second purge-and-trap GC-MS system over a 24 hour period. Preliminary results show nitrification at the base of the euphotic zone to be a source of nitrous oxide. The operation numbers of sampled locations are given in Table 12 and shown in Figure 5.

UNDERWAY MEASUREMENTS 1. Navigation and Bathymetry (Anthony W. Isenor) The navigation system onboard CCGS Hudson consists of a differential GPS receiver and AGCNAV. The receiver is one of many NMEA feeds into a multiplexer that provides all the NMEA strings to a PC on the bridge. The PC, which is running AGCNAV software, then rebroadcasts the NMEA strings to distribution units in the computer room, which provide 16 output lines for the working labs. The resulting broadcast navigation strings are at about 1 Hz. The navigation data are then logged at one second intervals on a PC. AGCNAV is a PC based display and waypoint setting software package, developed at the Atlantic Geoscience Centre at BIO. This software graphically displays ship position, waypoints, course, speed, etc. to the various science working areas. The echo sounder system used for collecting bathymetric data at station locations consisted of a Raytheon Line Scan Recorder, Model LSR 1811-1 (serial number A101) connected to a hull mounted 12kHz transducer. The transducer beam width is 15 degrees. The sweep rate of the record was adjusted throughout the course of data collection to aid in identifying the bottom signal. One transducer is positioned on a Ram that can be lowered or raised depending on conditions. When the ram is up, the waterline to transducer offset is 6 m. When the ram is down, the offset is 8 m. 2. Vessel Mounted Acoustic Doppler Current Profiler (Murray Scotney) The Hudson was equipped with a hull mounted RDI Acoustic Doppler Current Profiler (ADCP). The transducer (serial number 177) had VM ADCP electronics (serial number 172). Logging, using Transect software on a 486 PC, was started on May 31 at 0120 Z in Halifax Harbour. Two different configurations were used for logging. From Halifax Harbour to Site 1 on AR7W, the configuration resulted in 5 minute averages in 4 metre bins. From Site 1 onward (June 4, 2001 at 0920 Z), the configuration resulted in 5 minute averages and 8 metre bins. The averaged data are stored to disk and backed up every few days. ADCP logging was stopped on June 15 at 0909 Z in Halifax Harbour. 3. Continuous Flow Multisensor Package (CFMP) (Jeff Anning) The Continuous Flow Multisensor Package Water used during this cruise is a new design as compared to past years. The Ocean Physic Section at BIO developed the CFMP. The package receives water from a ship intake line located at approximately 4m depth. The package was setup in the forward lab. The package measures and logs temperature, conductivity and fluorescence. The system was setup with Seabird temperature (SN 032169) and conductivity (SN 041656) sensors and a Wetlabs fluorometer (SN WS1S- 621PSS). Exact time and positions were provided by a Northstar GPS and logged with the other data. In addition discrete water samples were collected every 15 minutes by an Alpkem auto sampler for later analysis for nitrate and silicate. The computer also logged the time and position of these samples. 4. XBT and XCTD (Igor Yashayeav) Expendable Bathythermographs were deployed along the AR7W line on the way from Greenland to Labrador. The XBTs were model 7 from Sparton of Canada. This type of probes is capable of measuring to maximum depths of 800 m at the full cruising speed 15 knots). The vertical resolution of the measurements was about 0.6-0.8 m. 92 XBTs were launched during the cruise. Continuous deployment of XBT along the AR7W line at 2-4 kilometer intervals revealed inhomogeneities in the thermal structure of the upper layer. Dominant scales appear to be between 20 and 40 kilometers. Preliminary data are shown in Figure 3. 5. Meteorological observations The ship's crew logged routine reporting of meteorological variables. 6. Atmospheric Chemistry There was no atmospheric chemistry program. Appendix 1: Operation Notes Report As Completed On: 28/Jun/2001 Cruise Number: 2001022 Note Number: 1 Entry Time: 03/Jun/2001 10:17:16 Note Made By: Anthony Isenor Operation ID: 38 The NMEA strings were not being broadcast from the bridge computer. The NMEA and time string in the Seabird HDR file were added based on NMEA position strings available on the bridge. Note Number: 3 Entry Time: 04/Jun/2001 15:20:23 Note Made By: Anthony Isenor Operation ID: 54 After the station, Murray worked on the carousel and loosed up the trip mechanism for the number one bottle. Note Number: 2 Entry Time: 04/Jun/2001 13:26:32 Note Made By: Anthony Isenor Operation ID: 54 About 2 minutes spent at the bottom due to problems with the CTD winch. Note Number: 4 Entry Time: 04/Jun/2001 18:30:19 Note Made By: Anthony Isenor Operation ID: 60 This was a mooring release test. Note Number: 5 Entry Time: 05/Jun/2001 10:33:58 Note Made By: Anthony Isenor Operation ID: 71 Had to stop at 600 dbar for a brief period due to problems spooling the CTD winch. Note Number: 7 Entry Time: 05/Jun/2001 14:35:42 Note Made By: Anthony Isenor Operation ID: 72 After this operation, Murray replaced the top Orings on bottles 2, 10, 17 and 19. Also replaced the small Oring around the air vent on bottle 17 and 19, and on 19 replaced the air vent plug. Note Number: 6 Entry Time: 05/Jun/2001 13:26:10 Note Made By: Anthony Isenor Operation ID: 73 Start time is wrong Note Number: 8 Entry Time: 05/Jun/2001 20:08:55 Note Made By: Anthony Isenor Operation ID: 79 A long wait at 224 dbars due to meter block problems. Note Number: 9 Entry Time: 06/Jun/2001 20:25:34 Note Made By: Murray Scotney Operation ID: 90 Changed bottle in position 21 after operation 90. New bottle is S003. Note Number: 10 Entry Time: 07/Jun/2001 09:37:59 Note Made By: Anthony Isenor Operation ID: 95 Problems when trying to display bottle trips at the bottom of this cast. ODIN was reporting that there were no bottle trips for the station, and that the user should go to prepare sample ID numbers. I could duplicate the problem when I started the next cast. Same thing happened, I prepared the sample IDs and sampling, then went to Operation Initiate and Bottle trips - nothing there. I noticed the size of the database, about 3 Mb. That seemed large so I compacted the database. Then, going back into ODIN on the same PC and the problem was not there. Note Number: 11 Entry Time: 07/Jun/2001 11:48:07 Note Made By: Anthony Isenor Operation ID: 98 Stopped at about 1856 dbars on down cast due to problems with winch. Note Number: 12 Entry Time: 07/Jun/2001 19:34:02 Note Made By: Anthony Isenor Operation ID: 102 Had a long wait at 280 dbars due to problems with the metering block. About 25 minutes at this depth. Note Number: 13 Entry Time: 08/Jun/2001 10:01:44 Note Made By: Anthony Isenor Operation ID: 105 The CTD cast that was initially operation 106 was changed to 105. Note Number: 15 Entry Time: 10/Jun/2001 14:55:29 Note Made By: Anthony Isenor Operation ID: 211 The dry deck sheet has the secondary sensor salinity and temperature for all bottles. This is because we think the primary sensor has stopped functioning properly. Note Number: 14 Entry Time: 10/Jun/2001 13:57:53 Note Made By: Anthony Isenor Operation ID: 211 It appears that the CTD primary system has problems. Both the primary salinity and oxygen are providing bad data. We suspect the primary pump. Note Number: 16 Entry Time: 10/Jun/2001 20:47:44 Note Made By: Anthony Isenor Operation ID: 211 After the CTD was recovered, the primary pump was changed. Took off pump model 5T SN 051775. Put on pump model 5-02 SN 050675. Note Number: 17 Entry Time: 11/Jun/2001 10:07:07 Note Made By: Anthony Isenor Operation ID: 236 After this operation, both the primary and secondary lines were flushed with Triton X100. Note Number: 18 Entry Time: 11/Jun/2001 19:03:06 Note Made By: Anthony Isenor Operation ID: 239 After completing this operation, the primary pump was replaced with pump SN 050538, model 5-02. This was because tests showed the pump was not pumping as fast as it should (used ALIGNCTD tests to show the offset was about 7 scans). Note Number: 20 Entry Time: 12/Jun/2001 13:58:47 Note Made By: Brian Irwin Operation ID: 241 Seacat calibration cast. Note Number: 19 Entry Time: 12/Jun/2001 12:14:16 Note Made By: Anthony Isenor Operation ID: 243 Primary pump gave more problems on this cast. After cast, the original pump was put back on and a new cable was used.
