Directory entires that have specified Barents 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). To see the full list of regions, see the regions list. To browse the catalog based on the originating country (leady party), see the list of countries.

1. Restoration of the salmon stock in the Tuloma river system

The possibility of restoring the salmon stocks in the Tuloma system is assessed by collecting background information on the river system: present fish fauna, habitat quality, migratory routes etc. Planning the restoration including technical and management aspects is under way.

2. Monitoring of the Atlantic salmon stocks of the Teno (Tana) and Näätämö (Neidenelva) river systems, northernmost Fennoscandia.

Monitoring of the salmon stocksof the Teno and Näätämö river systems is based on long term data collection on juvenile salmon production, biological characteristics of the spawning stock, origin of salmon (wild/reared) and statistics on fishery and catches. Information on other fish species than salmon is also available.

3. RADNOR - Radioactive dose assessment improvements for the Nordic marine environment: Transport and environmental impact of technetium 99 (99Tc) in marine ecosystems

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.

4. Radionuklide in Fischen eingangs zur Barentssee : Radionuclides in fishes at the beginning of the Barents Sea

Our projects will investigate the effects of radioactive wastes on marine ecosystems. Two marine ecosystems have been chosen for projects: 1) the dumping site for low level radioactive waste in the north-east Atlantic and 2) the western part of the Barents Sea. The data on the radioecology of North Sea and Baltic Sea obtained in our long-time monitoring programmes will serve as a basis for the interpretation of the project´s results.

5. Trajectories of Marine Ecosystem Response to Arctic Climate Change: A Barents-Bering Sea Comparison

Multi-institutional, international cooperative project to determine the possible responses of Arctic marine communities to future global climate change by comparing retrospective patterns in benthic composition and distributions to past climatic events in the Barents and Bering Seas.
