Directory entires that have specified Greenland Sea as one of the geographic regions for the project/activity and are included in the AMAP, ENVINET, SAON and SEARCH directories. Note that the list of regions is not hierarchical, and there is no relation between regions (e.g. a record tagged with Nunavut may not be tagged with Canada).

-Development of methods to enhance the rate of toxin depuration ( detoxification), especially in shellfish species of high economic value and prolonged retention e.g., King Scallops -Understanding the reaction products and metabolic transformations of toxins in shellfish tissues. -Determine the relationship between algal population dynamics ( including free cell and encysted stages ) to seasonal and spatial patterns of toxicity in shellfish populations. -Assess the effects of harmful algae on the various stages in the life history of shellfish ( Larvae, Spat, Adults ). -Investigate sampling frequencies and protocols ( live shellfish sampling ).

Radioactivity in the Arctic environment is a central topic within environmental pollution issues. Increased discharges of technetium-99 (99Tc) from the nuclear fuel reprocessing plant Sellafield to the Irish Sea has caused public concerns in Norway. This project (acronym “RADNOR”) includes model and monitoring assessments and improvements, assessment of current and novel abiotic and biotic dose parameters and dose calculations and use of realistic climatic background scenarios in order to assess corresponding consequences for transport of radioactive pollutants. RADNOR consists of three main components: part 1, the determination of levels and time series of 99Tc in benthic and pelagic food webs; part 2, containing working packages on improvements to the understanding of site-specific and time-dependent sediment-water interactions (KD), kinetics of accumulation (CF) and body distribution in marine organisms, including contaminated products for the alginate industry and part 3, dealing with model hindcasts and observations for spreading of 99Tc from the Sellafield nuclear reprocessing plant during the 1990s and improvement of the NRPA dose assessment box model. From the model outputs, doses to man and environment will be calculated resulting in a valuable database for use within environmental management and for decision makers.
Due to the high organochlorine concentrations reported in Arctic top predators, and the potential transport of contaminants with the drifting sea-ice in the Arctic, organisms constituting lower trophic levels living in association with sea-ice have been proposed as susceptible of uptake of high loads of organic pollutants. The present project studies the organochlorine occurrence in organisms living in the marginal ice zone north of Svalbard and in the Fram Strait. This includes both ice fauna (ice-amphipods), zooplankton, polar cod and different seabird species foraging in the marginal ice zone. Our objectives are to investigate: *The bioaccumulation of organochlorines in ice-associated amphipods in relation to diet preference, spatial variation due to sea ice drift route, size, sampling year, uptake and distribution within the body. *Comparison of organochlorine contamination in pelagic and ice-associated organisms at the similar trophic position, to investigate the effect of sea ice as a transporter and concentrator of pollutants. *Spatial variation in zooplankton species, related to differences in water masses and exposure to first year or multi year sea ice. *The contamination load in different seabirds feeding in the marginal ice zone, in relation to diet choice and estimated trophic position, taxonomically closeness and the induction of hepatic CYP P450 enzymes.
