These data set regards the average p,p'-DDE and HCB concentration (0.86±0.98 and 0.37±0.17 ng g–1 wet wt. respectively) measured in krill samples collected from the Ross Sea (71°20’S– 72° 331’S/170° 22’E–178° 04’E) in January 2000. Average PCB concentrations in these samples were much higher (167±85 ng g–1 wet wt.), and congener- specific PCB profiles showed a prevalence of low-chlorinated isomers (tetra-PCBs accounted for most of the 48 residue). This pattern differed from that usually detected in organisms from low and mid latitudes, and it was likely due to global fractionation at high latitudes. Isomer patterns in organisms from the Ross Sea were similar to those of Kanechlor, a technical mixture mostly used in Japan and other eastern Asian countries, roughly located at the longitude of the Ross Sea. On a lipid weight basis, concentrations of total polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (DFs) in the same krill samples were 27 pg g–1, and those of non- and mono-ortho-substituted polychlorinated biphenyls (dioxin-like PCBs) were 0.9 ng g–1. About the presence of Organochlorine Pesticides in krill sampled at Ross Sea in Terra Nova Bay, during 2001/02. The concentrations of HCB, HCHs and DDTs found were 0.23 ± 0.01, 0.28 ± 0.04 and 0.18 ± 0.03 respectively while chlordanes (CHLs) were below the detection limit (MDL< 0.02 ng/g wet wt). Mean PBDE concentrations were 0.20 ng/g in krill whole body and 5.60 ng/g on a lipid basis. PCB levels were higher with one order of magnitude than PBDEs levels.

The total biomass, productivity and biodiversity of algae and bacteria from the sea ice and the water column was investigated in Terra Nova Bay. Sampling sites in the Terra Nova Bay area were used to survey the sea ice for algae and bacteria by drilling cores and using bottom ice, brine and using the entire ice core to look at biomass in profile. Initial chlorophyll concentrations were determined on all samples and additional sub samples were collected for analysis of bacterial and algal cell counts, carbon concentrations, DNA content, MAA composition, species biodiversity and cell numbers. Sea water under the ice was sampled at 5, 25 and 50m depths and similar analysis were performed. Light levels and termperature loggers were deployed in the sea ice for the duration of sampling and CTD (conductivity, temperature and chlorophyll concentration) profiles were taken in the water column every day at solar noon. A physical survey of the sampling area was also undertaken including snow depth, light attenuation through varying snow depths and under ice irradiance levels. Nutrient analysis (nitrate, silica and phosphate) was conducted on bottom ice samples, brine samples and water column samples.

Genetic variation of WB and TB colonies.

The distribution, taxonomy, physiology and feeding habits of pelagic amphipods was investigated. Amphipods were collected by plankton tow, baited traps, coring (coring through sea ice) or hand collections (from tide cracks). Approximately 2000 individual amphipods were collected. About 75% of the amphipods collected were preserved in vials of absolute ethanol for DNA studies. The remaining 25% were split evenly between 4-5% EM grade gluteraldehyde, 5-6% formalin, and frozen dried for SEM, gut content analysis and isotope analysis respectively.

    They will be examined for 
    1) an investigation of the diet of pelagic amphipods by means of visual microscopic gut content analysis, together with stable isotope analysis of carbon and nitrogen isotopic composition of the amphipod, 
    2) sequencing of the cytochrome c oxidase I (COXI) gene of each morphologically identified species and
    3) a comparison of species composition and their respective diets between pelagic amphipods from Terra Nova Bay, an area covered by sea ice and those found in the open water of the Ross Sea. 

    The rate of movement of amphipods was determined by experimentally exposing amphipods to increasing water temperature and measuring the distance traveled over 30 seconds at each temperature. The distribution of amphipods under the ice was determined by lowering a plankton net to a depth of 5m below the sea ice, withdrawing it, emptying it and counting the amphipods, 3 times at 4 hour intervals over 24 hours.

Little is known of the early development of Pleuragramma antarcticum prior to hatching. Abundant eggs and larvae were collected under the sea ice from Terra Nova Bay in October and November. The distribution, embryological development and biochemical changes in these eggs and larvae was the scope of an international investigation with particular emphasis on their resistance to freezing. Cores of congelation ice were sectioned to check for viable eggs in the solid ice at several sites between Coulman Island and the Drygalski Ice Tongue. A total of 118 sites were visited and tested for the presence of Pleuragramma eggs or larvae. Eggs which were found were kept in a flow through aquaria and sampled every 1 or 2 days to assess development. Eggs were examined and photographed under a dissection microscope and fixed for histological examination and to evaluate modern DNA haplotypes of the Ross Sea Pleuragramma population. Freezing and melting points of eggs, larvae and associated body fluids was done by microscopic observations in a cryometer.

Plankton was sampled at a single site (74° 38.474' S, 164° 12.473' E) between 14 Nov 2007-06 Dec 2007 about 1 km to the south of Gondwana Station during the 07-08 season to determine if there is a different larval community at different depths. Plankton was sampled at four depths (25, 50, 75, and 100 m) in random order. A CTD probe produced a depth profile of salinity, temperature and chlorophyll to relate to the depth distribution of the larvae. Three replicate samples were taken at each depth. The 50 m samples were sorted fresh, larvae quantified and specimens photographed and preserved for DNA sequence analysis and morphological description. The other samples were preserved in a formalin based Steedman's fix and taken to the University of Auckland for analysis.
