Along AR7W, the stations were full-depth WHP small volume rosette casts with 
up to 24 rosette bottles.  Water samples were analyzed for CFCs, carbon 
tetrachloride, total carbonate, alkalinity, oxygen, salinity, and nutrients.  
On some casts, samples were collected for 129I (iodine-129).

A.4.  PHYSICAL - CHEMICAL PROGRAM

A.4.1.  NARRATIVE

This expedition was conducting operations in support of four 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 2002/2003.  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 continuation of 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. 
A particular element of this year's program is the recovery of two moored 
sediment traps near the old OWS Bravo site in the Labrador Sea.  These have 
been measuring the particle flux at 200 and 1000 metres over the past 12 
months. 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. 

The fourth objective is to recover and set moorings for various programs within 
the Ocean Sciences Division, BIO.  Moorings were recovered and set on the 
continental slope at the end of the Halifax Section, at the mouth of the 
Laurentian Channel and in Flemish Pass.  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.  Two moorings were recovered from Makovik Bank 
on the Labrador Shelf.  These moorings measured ice draft and water velocity 
profiles in support of the division's sea ice research program on the Labrador 
and Newfoundland shelves.  A complex sediment trap mooring was recovered from 
the continental rise offshore of the Laurentian Channel.  This mooring had been 
set as a contribution to the Canadian SOLAS program in April 2003.  The mooring 
failed in June 2003; the failure is believed to be caused by the mooring being 
caught a trawl or a towed array.

The fifth objective was to deploy profiling floats as a Canadian contribution 
to the International GODAE/Argo program.  Six floats were deployed; two in the 
Slope Water region and four in the Labrador Sea.


A.4.2.  RADIOISOTOPE SAMPLING PROGRAM  
        (John Smith)

Near surface water samples were collected for 129I from a near surface rosette 
bottle at 20 stations on the L3 (AR7W) line.  Full depth sampling for 129I was 
carried out at 5 stations on the same section. See table A.2.1 for the list of 
operations during which 129I was sampled.



A.5.  BIOLOGICAL PROGRAM

A.5.1.  NARRATIVE

The biological program conducted as part of cruise 2003038, 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: 
1) a phytoplankton biomass/primary productivity program conducted by Glen 
   Harrison and Jeff Anning with assistance from Katherine Power (latter for 
   Trevor Platt and Ed Horne),
2) a microbial program conducted by Paul Dickie (for Bill Li), 
3) a mesozooplankton program conducted by Les Harris and Tim Perry (for Erica 
   Head),
4) a dissolved organic carbon/community respiration program conducted by Jay 
   Bugden (for Paul Kepkay), and
5) a sediment trap program conducted by Jeff Anning and Glen Harrison.

The ultimate aim of these studies is twofold: 
1) 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
2) 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).


A.5.2.  STABLE ISOTOPE STUDIES OF CARBON AND NITROGEN (NITRATE AND AMMONIUM) 
        UTILIZATION 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 35-80 m) were determined using stable isotope tracer (13C 
and 15N) methods.  Incubations experiments were carried out in on-deck 
'simulated in-situ' incubators.  A total of 9 experiments were conducted (see 
Table A.4.2.1).  Carbon and nitrogen-based primary productivity rates along 
the L3 line will be related to vertical fluxes of particulate biogenic carbon 
and nitrogen derived from our sediment trap deployed on the "Bravo" mooring in 
2002.

In addition to productivity measurements, samples from two deep casts (L3_14 & 
L3_15) were collected for determination of suspended particulate organic 
carbon (POC) and nitrogen (PON) 1,000 m.

A.5.3.  ZOOPLANKTON SAMPLING  
        (L. Harris, T. Perry)

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 were taken at 50 stations, using both a 3/4 metre 200 _m 
mesh ring net and a 1/2 meter 76 um mesh ring net. At all stations, tows were 
made from 100 meters to the surface. Additional deep stratified tows (1000 
meters to the surface) were taken at 11 of the stations in the Labrador Sea 
using a multi-net. Samples will be analysed for species composition, copepod 
stage structure and biomass.  See Figure A.4.2.1 for station locations where 
nets were used.



A.5.4.  MEASUREMENTS OF COPEPOD REPRODUCTION RATES   
        (L. Harris, T. Perry)

Egg production rates of Calanus finmarchicus, the dominant copepod species, 
were measured at 9 stations in the Labrador Shelf.

                diamond) locations for 18HU2003038_1.


A.5.5.  TOTAL ORGANIC CARBON (TOC) AND MICROBIAL COMMUNITY RESPIRATION  
        (Jay Bugden and Paul Kepkay)

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 by size fractionating the 
TOC, information on the fate of carbon in this marine environment may be 
elucidated.

During CCGS Hudson cruise 2002-038 seven stations were sampled at the surface 
and at the chlorophyll maximum (usually between 3 and 50m depth) for gross 
microbial community respiration, and for the same stations only the surface 
was sampled for size fractionation of TOC (ultrafiltration). The stations 
sampled are listed below.  TOC depth profiles were also collected from the 
stations indicated in the table below.

A.5.6.  PRIMARY PRODUCTION MEASUREMENTS  
        (Jeff Anning)

Water samples for primary production experiments were collected from the 
rosette at 10 stations. For each incubation, 33 aliquots were inoculated with 
14C as sodium bicarbonate and then incubated at in situ temperatures at 30 
light levels (+ 3 dark bottles) for approximately 3 hours. At the end of the 
incubation period the cells were harvested onto GF/F glass fiber filters for 
later counting in a scintillation counter. Duplicate chlorophyll, duplicate 
particulate organic carbon, one HPLC, and one Absorption Spectra sample were 
collected for all incubations.

Photosynthesis/irradiance incubations were conducted at the following 
stations:

A.5.7.  BACTERIAL ABUNDANCE AND PRODUCTION OF MICROBIAL PLANKTON  
        (William Li and Paul Dickie)

Seawater samples were collected from the water sample bottles at all stations 
and all depths for subsequent Flow Cytometric analysis. They were preserved 
with a final concentration of 1% filtered paraformaldehyde and frozen in 
liquid Nitrogen. Dr. Bill Li will look at these for enumeration of pico-
phytoplankton, bacteria and viruses. At 17 stations on the Labrador- Greenland 
transect, incubations were conducted on water from the surface to 150 meters 
for uptake of tritiated leucene into bacterial cells. This gave an estimate of 
the rate of increase of marine heterotroph biomass in the photic zone. An 
additional experiment was performed at station L3-16 using 21 water depths 
from surface to 3499 meters. A Dilution experiment was done to test the 
effects of predation on the experiment.  Water samples were also collected 
from near the surface at most stations, preserved with a 1% final 
concentration of formaldehyde, stained with Dapi dye and filtered onto .8(m 
black polycarbonate filters. These will be kept frozen in the dark until they 
can be counted under a fluorescent microscope for nano-zooplankton.


A.5.8.  MOORING SEDIMENT TRAPS   
        (Glen Harrison and Jeff Anning)

Two sediment traps (from 175 m and 1,053 m) were successfully recovered at the 
"BRAVO" mooring site (M1349) on 25 July, 2003.  The trap design employed was 
developed at BIO (Bioflux traps), it has a 24-cup capacity and internal 
Tattletale computer for programming particle collection intervals.  Cups were 
programmed to collect material for 15-day intervals starting 12:01 (GMT), 15 
July, 2002 and ending at 24:00 (GMT), 10 July, 2003.  The shallow trap 
carousel worked properly through the first 14 cycles at which point rotation 
stopped.  The cause of this malfunction, whether power or mechanical, is 
unknown at this point.  It was noted that the PVC cover for the carousel was 
warped but this could have resulted from water pressure in the funnel upon 
recovery.  The deep trap appeared to function properly for all 24 cycles.  A 
preliminary inspection of the trap contents (Fig. 4.2.2) revealed a 
preponderance of diel-migrant crustacean "swimmers" in the shallow traps and 
numerous deep sea shrimp, jellies and other large organisms (e.g. fish) in the 
deep traps.  Sedimenting phyto-detritus was detected only in the first 
(shallow and deep traps) and last (deep traps) few cups of the series.  Note 
the excessive accumulation of biogenic material in cup #14 of the shallow 
trap, the point at which the carousel stopped rotating.  This cup would have 
collected material for six months (26 January - 25 July, 2003).  The material 
was highly decomposed (as evidenced by black appearance of the material and 
presence of H2S) as opposed to the other cups where the Hg preservative was 
adequate to retard decomposition.  The small amount of biogenic material in 
cups #15-24 of the shallow trap was likely cross-contamination after the 
carousel seized.

                mooring (M1349) deployed 4 July, 2002 and recovered, 25 July 
                2003.  Cup collected material for 15-day intervals; starting 15 
                July, 2002 and ending 10 July, 2003.


A.6.  MAJOR PROBLEMS AND GOALS NOT ACHIEVED

The pump on the Autoanalyzer system failed early during the sampling of the 
AR7W section.  The appropriate spares were not on board so all remaining 
nutrient samples were frozen and were brought back to BIO for subsequent 
analysis.


A.7.  OTHER INCIDENTS OF NOTE

The biological sensors were left on the CTD package on station 22 (operation 
291) of the AR7W section.  The Wet Labs flourometer flooded around 1500 metres 
and this caused a data transmission failure on the CTD.  When the CTD was 
recovered and the biological sensors were removed, the CTD unit worked fine.  
The light sensor survived its cast to about 1600 metres without damage 
although it is only rated to 400 metres.

We had considerable difficulty with the instrumented blocks on the CTD boom 
early in the trip.  After trying both of the CTD blocks (equipped with wire 
tension sensors) without resolving all the problems, we went to the spare 
block from the multi-net system.  This block worked fine although it does not 
measure tension.  Fortunately the seas were extraordinarily calm and hence 
tension measurements were not necessary.

B.  UNDERWAY MEASUREMENTS

B.1.  NAVIGATION AND BATHYMETRY  
      (Jeff Jackson)

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 10 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 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.


B.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 July 13 at 1739 Z off the coast off the Nova Scotia while 
performing operations on the Halifax Line.

The configuration used for logging resulted in 10-minute averages in 4 meter 
bins. The averaged data are stored to disk and backed up every few days.  ADCP 
logging was stopped on August 5 at 11:13 Z in Halifax Harbour.


B.3.  CONTINUOUS FLOW MULTISENSOR PACKAGE (CFMP)  
      (Jeff Anning)

Water from approximately a depth of 4m was continuously pumped to the forward 
lab. The temperature, conductivity and fluorescence was measured and logged 
every 30 sec. The temperature and conductivity were measured with Seabird 
sensors (SBE 3F temperature sensor S.N. 032169 and SBE 4 conductivity sensor 
S.N. 040817) and the fluorescence by a Wetlabs flow through fluorometer (WSIS-
621PSS). Incident Photosynthetically Active Radiation was measured with a Li-
Cor Spherical Quantum Sensor and this data was merged with the sea water 
parameters. Exact time and positions were provided by a Northstar GPS unit and 
logged with the other data. In addition, discrete water samples were collected 
at regular intervals by an auto sampler for later analysis for nitrate and 
silicate. The computer logged the time and position of these discrete samples.


B.4.  XBT and XCTD  
      (Igor Yashayaev)

Expendable Bathythermographs were routinely deployed along the AR7W line on 
the way from Labrador to Greenland and in the area shown in figure B.4.2. The 
XBTs were model T4 and T7 from Sparton of Canada. These types of probes are 
capable of measuring to maximum depths of 500 m (T4) and 800 m (T7) at the 
full cruising speed 15 knots. The vertical resolution of the measurements was 
about 0.6-0.8 m. 107 XBTs were launched during the cruise (Table A.2.1 lists 
the operation numbers when these were deployed).

Continuous deployment of XBTs 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 B.4.1.  A couple miles to the east of the site 21 
(according to the standard AR7W/L3 station notation) XBT measurements revealed 
an intense cold eddy. This eddy was resurveyed with XBTs soon after completion 
of AR7W line. This XBT survey helped us to locate the center of the eddy.  
Figure B.4.2 demonstrates the average temperature between 100 m and 700 m from 
all XBT and CTD profiles in the area where we found the eddy. In addition, we 
conducted a full depth CTD station, some net tows and we deployed a profiling 
float at the location identified from the XBT survey as the center of the 
eddy.

              arrows mark the positions of the CTD stations; vertical bars the 
              positions of XBT drops.

FIGURE B.4.2: Average Temperature for the 100-700 metre layer in the vicinity of 
              the cold core eddy mapped on the eastern end of the AR7W section 
              during Hudson 2003-038.



B.5.  MVP  
      (Allyn Clarke)

The Moving Vessel Profiler (MVP) system was deployed while the vessel was in 
transit between near Station 21 on the AR7W section and station 10 on the L4 
line.  The system was activated every 15 minutes.  The system cable had a 
fault around 480 metres, so for the vessel cruising speed of 12.4 knots, 
profiles were limited to a little better than 160 metres.  The system was 
configured with an Applied Microsystems Ltd, CTD Microsensor Instrument with 
serial number 7013.  This CTD is equipped with the following sensors.

Sensor        Type                  Range             Accuracy
------------  --------------------  ----------------  -----------------
Pressure      Strain gauge          0 - 500 dbars     ±0.15 dbars
Conductivity  Platinized electrode  0 - 7  (C Ratio)  ±0.0001 (C Ratio)
Temperature   Thermistor           -2 to 32 °C        ±0.0012 °C

The CTD sampled at 25 scans/second.  The MVP was also equipped with a WetLabs 
Model WS1S-120.SS #9602010 fluorometer.



B.6.  METEOROLOGICAL OBSERVATIONS

The ship's crew logged routine reporting of meteorological variables. 


B.7.  ATMOSPHERIC CHEMISTRY

There was no atmospheric chemistry program.

01/16/04  Bartolacci  SUM        Data Update; Various changes, see note  
          Updated sumfile sent by Jeff Jackson needed reformatting.  Following
            edits were made:
            • Edited first header line to include line number cruise name and leg,  
              ship name and date/name stamp.
            • Changed WOCE SECT to read AR07W instead of various alphanumeric 
              designations.
            • Changed OPERATION ID TO STNNBR.
            • Aligned all columns to correct WOCE spacing.
            • Changed Lat. hemisphere designation from E to W on following stations:
              15,119, 152, 158, 175, 180, 253, 365, 375, 412, 423, 433
              as only one of 2 or more cast codes had erroneous hemishphere and 
              none of the cast codes were near a hemisphere change.
          Ran file through sumchk.  Sumchk would not accept the cast codes BD 
            and ED (begin descent and end ascent) for 65 stations.  Other than 
            those warnings file passed with no errors and was placed in parent 
            directory to replace previously submitted sumfile.
