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).

1. Ecogeochemical mapping of the eastern Barents Region (Barents Ecogeochemistry)

Geochemical mapping project based on multimaterial and -elemental method covering the NW Russia and adjacent areas of Finland and Norway. NW-Russia is of strategic importance not only for Europe but also for the sosio-economic development of the whole Russia for its richness in natural resources. Their use must be based on environmentally acceptable principles. In addition, within the area exist numerous industrial centres whose environmental impacts are unknown. The information produced by the project is significant for the future development of the area and remedial measures of the environment. The project lead by the applicant, will be carried out in 1999-2003 in cooperation with Russian and Norwegian partners.

2. Long-term effects of offshore discharges on cold water zooplankton: establishing a test system for chronic exposure to offshore discharges

During the last decade the concern regarding environmental effects of the offshore industry has shifted from effects of drilling discharges on benthic communities, towards a stronger focus on the water column and effects on the pelagic ecosystem. At the same time, oil and gas development is expanding in the Norwegian and Russian sectors of the Barents Sea. In this regard, a project has been initiated to look at responses of especially Calanus spp. and other copepod species to long-term, sublethal exposure to selected offshore discharges and discharge components, as well as accidental oil spills. Calanus spp. is ecologically the most important zooplankton species along the Norwegian shelf and in the Barents Sea. A laboratory based facility for culture through several generations is being developed through this project. In addition, the impact of oil compounds on the cold-water and arctic Calanus species-complex will be examined by carrying out a series of laboratory (some at Ny Ålesund) and ship based experiments. The response parameters will include both behavioral (feeding, mate finding, avoidance) and physiological (mortality, egg production, development rates, oxygen consumption and assimilation efficiency) parameters. The ultimate outcome of this research is expected to be a supporting instrument for ecological risk assessment of offshore discharges, which is highly relevant both to the North Sea, the mid-Norway shelf and the Barents Sea.

3. Environmental effects of offshore oil activities: experimental tests of petroleum-associated components on benthos at community, individual, and cellular levels

This project will examine benthic processes in arctic and mid-latitude regions in order to derive specific conclusions on the sensitivity of benthic organisms and communities to acute spills of petroleum-related chemicals and routine releases of drill cuttings. We will carry out a series of controlled experiments on whole sediment communities and individual benthic organisms with additions of drill cuttings and petroleum-associated contaminants, arriving at a set of hypotheses on the likely impacts on the benthos of petroleum production activities at higher latitudes. A series of testable hypotheses will be formulated based on an examination of real-world monitoring data sets collected under Norway’s Petroleum Regional Monitoring Programme and results of mesocosm experiments performed previously at the Norwegian Institute for Water Research (NIVA) Station at Solbergstrand. These data sets will be examined in order to identify the geographic scope of responses to petroleum industrial activities. Through this work, we intend to propose procedures to improve the interpretation of benthic monitoring data for diverse environmental regions in Norway. The project is linked to several on-going NFR projects within the Polarklima programme. By involving a Ph.D. student the project will advance the education and training of young scientists in the field of biological effects studies related to petroleum development and exploration activities.

4. Transfer of organic pollutants from the abiotic environment to the lowest tropic levels of the ice associated food chain

The aim of the project is to detrmine the content of organic contaminants in sea ice (including dirty ice), sea water (particulate and dissolved), snow, ice algae and phytoplankton collected in the marginal ice zone of the Barents Sea and in Fram Strait, and to calculate bioconcentration factors from the abiotic compartments to the lowest trophic levels of the food chain. Silicate measurements were included in the Fram Strait as water mass tracer. The Barents Sea represents an area influence mainly by first year ice with sea ice formed in the area and or in the Kara Sea, and and strongly influenced by the inflowing two branches of water of Atlantic origin. Samples were collected on a transect along the ice edge and at two transects into the ice. The stations across the Fram Strait were taken in regions affected by water masses and sea ice from differents regions and age. In the western sector, the upper water column was influenced by the inflowing west Spitsbergen current of Atlantic origin and mainly with first-second year ice, while the easter station was influenced by outflowing water from the Arctic Ocean and multiyear sea ice of more eastern origin.
