Murray Scotney (TOS, BIO) OBJECTIVES: The main objective of the mission was to determine the overwintering vertical depth distribution of the copepod Calanus finmarchicus along the AR7W section across the Labrador Sea. This organism dominates the zooplankton biomass in North Atlantic waters north of the Gulf Stream, although its abundance and distribution is influenced by changes in hydrography resulting from climatic variations. There is currently an international collaboration to determine life history parameters, including overwintering depth distribution, in order to model the space/time dynamics of C. finmarchicus in the northwest sub- polar gyre, with a view to predicting how they might be affected by global warming. This cruise, together with one conducted in June/July (Mission no. 2002032), and alligned cruises in the Irminger sea, by a group from the UK, will provide data for modelling. Secondary objectives were: to measure a series of other biological/environmental variables (concentrations of the copepod Oithona, phytoplankton, bacterial, nutrient, oxygen and dissolved organic carbon concentrations); to determine biological rates (primary and bacterial production and microbial respiration); to determine levels of metabolism in zooplankton (by use of biochemical indices); to determine underwater light fields; and, to make standard hydrographic measurements (temperature, salanity). A final objective of the mission was the deployment of a mooring on Makkovik Bank. Further details of these activities are given in the reports of the individual scientists included below.

Scotney) Two instrumented moorings were deployed December 1st, 2002 on Makkovik Bank, approximate position 55 24.50 N and 58 03.70 W. One mooring contained an Ice Profiling Sonar to measure ice thickness and the other an Acoustic Doppler Current Profiler to measure ice movement and water currents. These moorings are to monitor the freshwater flux within the pack ice along the Labrador Shelf as part of Climate studies and contributing to international ASOF (Arctic, Sub-Arctic Ocean Flux) program. Funded through PERD Climate program sector. Recovery is scheduled for July 2003. Overwintering vertical and spatial distribution of Calanus finmarchicus along the AR7W section across the Labrador Sea. (Erica Head, Ed Horne, Tim Perry) The main aim of the cruise was to collect samples to enable us to establish the overwintering depth distribution of the copepod Calanus fimarchicus in the Labrador Sea. We sampled zooplankton using a Multi-net sampler fitted with 200 mm mesh nets at a total of 17 stations of the L3 (AR7W) section between Hamilton Bank and Cape Desolation (Greenland). At 11 of these stations we sampled to 1000 m or to the bottom (in the slope regions), while at 6 we sampled to 2000 m. Depth strata were every 200 m between 1000 m and the surface, and every 250 m between 2000 and 1000 m. The Multi-net system worked flawlessly and while most times wind strengths were below 35 knots, at one station we managed a totally successful recovery when wind strengths had reached 40-50 knots. A total of 111 formalin preserved samples were taken for species identification and enumeration. Some tows were given to a colleague (Lidia Yebra Mora) from the Plymouth Marine Laboratories in UK for the analysis of levels of enzyme indicative of levels of metabolic activity in selected stages and species of copepods. These samples were preserved in liquid nitrogen. Sampling stations at which Multi-net tows were carried out.

For each incubation, 33 aliquots were inoculated with sodium bicarbonate 14C 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 fibre filters for later counting in a scintillation counter. Photosynthesis/Irradiance incubations were conducted at the following stations: 2002-075 PI Log Station Event/ Date Time ID Depth CTD GMT ——————— —————— ———————— ————— —————— ————— L3-01 1 12/01/02 14:00 259575 4 259567 20 L3-03 13 12/02/02 19:30 259592 4 259584 30 L3-10 42 12/03/02 19:00 259666 4 259660 10 L3-16 77 12/04/02 15:30 259732 4 259724 30 L3-20 120 12/05/02 15:30 259794 4 259787 20 L3-24 153 12/06/02 16:00 259856 4 259849 20 L3-21 173 12/07/02 10:45 259938 4 259931 30 L3-17 201 12/08/02 14:20 259974 4 259967 20 L3-11 210 12/09/02 13:15 260033 4 Optical Measurements (Edward Horne) Once per day for the period Dec 1- Dec 8 an optical profile was made with a Biospherical Instruments Mer2040 profiler to a depth of 100m. The locations for the stations are the same as those for the PI measurements. In addition, water samples were draw in the upper 100m of the CTD profile at the station and analyzed for Colored Dissolved Organic Matter (CDOM). CDOM was low for all stations and with chlorophyll concentrations of less than 1 micro gram per liter the water was very clear and blue light penetrated best. 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 inorganic carbon and nitrogen) of phytoplankton in the Labrador Sea. Carbon dioxide (CO2), nitrate (NO3) and ammonium (NH4) utilization rate measurements, due to the expectation of icing weather conditions on deck this time of year, were modified from the standard deck incubation protocol to P-I style experiments performed in the lab, similar to those described by J. Anning. A total of 8 experiments were conducted (see Table). 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 July and scheduled for recovery in July, 2003. In addition to productivity measurements, samples from one deep cast (L3_17) were collected for determination of suspended particulate organic carbon (POC) and nitrogen (PON) from surface to ~1,000 m.

These samples were preserved with 1% final concentration of filtered paraformaldehyde and frozen in liquid nitrogen. They will be analyzed at BIO by Dr. Bill Li for marine pico- phytoplankton, bacteria and viruses. At all stations occupied (except #s 8 and 18), water from all depths from surface down to at least 100 meters was incubated with tritiated leucine to determine rates of increase of heterotrophic (bacterial) biomass. A total of 19 Depth Profiles were obtained. For most stations (17/24), the uppermost sample (closest to the surface) was checked for nanozooplankton. These samples were preserved with 1% formaldehyde, filtered in 30 ml aliquots onto 0.8 micron polycarbonate filters and stained with DAPI dye. They will be kept frozen until counting can be done with a fluorescence microscope. Zooplankton studies (Lidia Yebra Mora) Oithona project In order to study distribution of Oithona and other species in the Labrador Sea, vertical nets were performed every other station from St. Johns to Greenland along the L3 transect. Samples were collected with Bongo (63 um) and WP2 nets (200 um), from 0 to 100 m, and fixed with formalin 4%. At PML, species abundance and distribution will be determined, and compared with the data obtained at the same time in the Irminger Sea. Zooplankton biomass and growth Bongo and WP2 nets were used also to collect ZP from 0-100 m, along line L3. On board, samples were fractionated by size: 63-200, 200-450, 450-1000 and >1000 um, and frozen in liquid Nitrogen. At PML (Plymouth Marine Laboratory), biomass and structural growth will be determined. Biomass will be estimated as protein content, following the method of Lowry et al. (1951), modified by Rutter (1967). Growth will be approached by the method of Chang et al. (1984), modified by Yebra (2002). Relationship between hydrography and growth will be also studied. Calanus finmarchicus, growth or dormancy? When available groups of 20 CV of C. finmarchicus were selected from the vertical hauls and from the MultiNet, and stored in liquid Nitrogen. At PML, biomass and growth of copepods collected with vertical nets (0-100 m) will be compared with the ones from the MultiNet (0-1000 m). Growth rates will be also compared with growth of C. finmarchicus collected in the same period in the Irminger basin with the ARIES net. When available, groups of 10 CV C. finmarchicus were collected from the Multinet tows (0-1000 m) and frozen in liquid Nitrogen. Samples will be sent to Aberdeen to analyse lipid content. Data will be also compared with the ones from the Irminger Sea, at the same period. Stations sampled for zooplankton studies by L.

Bugden for P. 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 2002-075 nine (9) stations were sampled at the surface and at the chlorophyll maximum (usually between 10 and 30m 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. List of stations and what was sampled by Jay Bugden on CCGS Hudson cruise 2002-075.

Thermal structure of the upper ocean from XBT (Expendable Bathythermographs). Every spring-summer BIO carries out physical, chemical and biological observations in the Labrador Sea along WOCE Hydrographic Repeat section AR7W (map). In 2002 this line was resurveyed in the end of the year, providing unique early winter measurements of the seawater state and biomass (Cruise 2002075, CCGS Hudson, Nov.29–Dec.12, 2002, Chief scientist: Erica Head). In addition to the CTD profiles along section AR7W/L3 (map), 105 XBT (Sparton T7) probes were dropped with a spacing of 5 miles and less providing the measurements from the sea surface to 830 m at the full cruising speed of the ship (15 knots). The vertical resolution of the measurements is 0.6-0.8 m. Continuous deployment of XBT along with the CTD casts provides a detailed thermal survey of the upper 800 m between the Labrador and Greenland shelves (the section plot is based on the data from the eastward passage of the line). A homogeneous layer up to 160 m thick created by the vertical mixing of the cold season is clearly seen through the western and central regions. The warm (>4.5°C) and salty Irminger Current (on the Greenland side), its warm core (>6°C) and sharp front are clearly resolved by the XBT profiles. A chain of small eddies with the warm cores between 150 and 200 m and horizontal scales between 20 and 45 km span over 200 km from the Irminger Current and are presumably shed from this current. This relatively deep location of their cores indicates that the cooling and mixing of the upper 150 m has also already started in the eastern part. Another warm water flow can be identified offshore the Labrador slope. It is 1.6°C colder than the Irminger Current, but still forms a strong contrast with the shelf and Labrador Current above and inshore. This warm flow has been strongly altered by the mixing and was capped by 150 m of cold water. The XBT profiles collected on the eastward passage of ARW7/L3 reveal a strong warm core eddy, coincidently centred at the deepest point in the middle of the line. This eddy was deeper than 800 m and at the crossing with the section its size was about 45 km (resolved by 12 XBT profiles). However, we were unable to identify the exact location of the centre of the eddy off to the section line. Below 110 m the eddy was up to 1C warmer the surrounding water, above 100 m the eddy was covered with cold mixed water similar to that in the other XBT profiles. Four days later after we found the eddy we dropped 16 more XBTs along a north to south section approaching L3_17 in order to better define this eddy and planned a deep CTD station at the station L3_17, where the warmest core was first found. This section captured the eddy, however it was shifted 25 km north from its previous location. The CTD cast at L3_17 8th as of December did not show any signs of the eddy (on the 4th the eddy’s centre was found right at the location of L3_17, but a CTD cast wasn’t conducted at that time). Warm and cold eddies play an important role in physical and biological processes in the Labrador Sea and are well described by moored and remote measurements, however we lack direct observations of water mass and biological structure of these formations. Hence, in the planning of future missions to the Labrador Sea, we suggest to consider a research opportunity if a distinct and deep eddy was identified from XBT or remote observations.
