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.

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.
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.
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.
In 1994, analyses of sediments and fish from Lake Ellasjøen on Bear Island revealed a surprising scenario. The analytical results indicated some of the highest values of the contaminants PCB and DDT in freshwater sediments and fish ever found in the Arctic. The 1994 results were based on limited amounts of samples. During 1996 and 1997 there were carried out new sampling and analyses of several samples. These results verify the results found in 1994. Since the POP-patterns found deviate considerably from the typical patterns expected for local contamination, no local source can be assumed to be responsible for the high POP values found. Thus, the questions that need to be addressed include the source of these contaminants, the transport pathways that deliver these contaminants to this site, total deposition and finally contaminant fate including biological uptake and effects. Previous investigations from the early 80’s on high volume air samples carried out at Bear Island revealed several long-range transport episodes from Eastern Europe. The overall objective of this project is to contribute significant new information to the understanding of contaminant pathways in the Arctic hydrosphere and to provide a better understanding of contaminant focusing in a sensitive polar environment. This will be accomplished through the development of a comprehensive mass balance study of the atmospheric loadings of PCBs and other contaminants to the Lake Ellasjøen watershed to determine the seasonal importance of atmospheric deposition on a remote polar island. Further, effort will be directed at assessing the relative importance of various source regions of contaminants to the island through an evaluation of contaminant signatures and back trajectories of pollution events.
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.
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.
