The project aims to describe the environmental status of marine sediments in van Mijenfjorden. This to provide baseline data of contaminants and biodiversity, as well as for monitoring of eventual contamination from industrial activities (coal mining).
(1) Collate information relating to the environmental transfer and fate of selected radionuclides through aquatic and terrestrial ecosystems in the Arctic. (2) Identify reference Arctic biota that can be used to evaluate potential dose rates to biota in different terrestrial, freshwater and marine environments (3) Model the uptake of a suite of radionuclides, both natural and anthropogenic to reference Arctic biota (4) Develop a reference set of dose models for reference Arctic biota (5) Compile data on dose-effects relationships and assessments of potential radiological consequences for reference Arctic biota (6) Integrate assessments of environmental impact from radionuclides with those for other contaminants.
The project aims to carry out an environmental assessment of the marine environment close to the three main settlements in the Isfjorden complex; Barentsburg, Longyearbyen and Pyramiden. The study comprises analyses of sediment geochemistry and soft-bottom benthic fauna. Attention is given to distinguishing atmospheric transport of contaminants from those arising from local sources.
The objective of this project is to study long term temporal trends of persistent organic pollutants and mercury in ringed seals from the Canadian arctic. The project rationale is that there are previous results for POPs and mercury in ringed seal tissues for many locations. Furthermore there may be regional differences in temporal trends due to geographical differences in POPs and mercury in marine waters and food webs within the Canadian arctic. It is relatively cost efficient to return to the same locations for additional samples using the same sampling and anlaysis protocols are were used in previous studies (see AMAP and Canadian Assessment Reports). Samples are being collected with the help of hunters and trappers organizations in each community. During 2000-01 samples are being collected at Resolute, Arctic Bay and Pond Inlet. The study will also analyse samples collected recently (1998/99) from Pangnirtung, Arviat and Grise Fiord. Results will be compared with previous data which the Principal Investigator generated in the 1980's and early 1990's. Preliminary results will be available in mid-2001.
Our broad area of enquiry is the role of polar regions in the global energy and water cycles, and the atmospheric, oceanic and sea ice processes that determine that role. The primary importance of our investigation is to show how these polar processes relate to global climate.
Our central geophysical objective is to determine how sea ice and the polar oceans respond to and influence the large-scale circulation of the atmosphere. Our primary technical objective is to determine how best to incorporate satellite measurements in an ice/ocean model.
To understand and model the processes by which Arctic deep water is formed on continental shelves by the modification of inflowing Atlantic and Pacific waters.

The aim of the project is to develop a method for analysis of toxaphene in biota from the marine environment. The project includes a modification/improvement of the method of the chemical analysis of PCBs and cholrinated pesticides used at the Danish Environmental Research Institute.
The aim of the project is to develop a method for chemical analysis of brominated flame retardants in marine biota. Furthermore their will be a litterature study of the concentrations of brominated flame retardants in the Arctic.
1. To determine the depth profiles of mercury (Hg) and lead (Pb) as well as manganese (Mn) and iron (Fe) in fifteen dated Arctic sediment cores over a three year period. Mercury is the main focus. 2. To quantify geographical trends in fluxes of the mercury and its enrichment factors in Nunavut, NWT, Nunavik, and Labrador. To link mercury findings with those of paleolimnological indicators, POPs, as well as indicators of biogeochemical processes of manganese and iron, all of which are obtained from the same cores, or cores from the same sites whenever possible. 3. To complement existing data on mercury in Arctic sediment cores with data generated over a much wider latitudinal and longitudinal range than previous work in order to provide a better understanding of Hg in Canada North. 4. Secondary to Hg, to provide loading data for Pb which may help elucidate the understanding of Hg pathways and sources.
