Kara Sea: projects/activities

To edit or add records to any of the catalogs, log in or create an account.

Directory entires that have specified Kara 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. Polar microbial ecology

Ecology of bacterioplankton and bacterioneuston in the polar seas, distribution, number, in situ heterotrophic activity, involvement in natural purification processes from oil pollution.

2. 'Karex-Pechora' expedition

The 'Karex - Pechora' expedition marine investigations by the research vessel 'Ivan Petrov' in the Kara and Pechora seas in August 2000, and by the research vessel 'Hydrolog' during September-October 2000. During August 2000 samples of marine water, suspended and bottom sediments at 30 oceanographic stations were analyses for contaminants. At 8 stations, hydrobiological investigations included sampling of benthic organisms, plankton and fish, for studies of bioaccumulation and transformation of contaminants.

3. Expedition of hydrographical vessel 'Nikolai Kolomeets'

The expedition by vessel 'Nikolai Kolomeets'included sampling of marine water, bottom sediments, benthos and plankton for studies of accumulation and transformation of OCs and estimation of related toxic effects on aqueous biocenoses. The marine studies took place during the period July-October 2000 in areas of the Pechora, Kara, Laptev, East-Siberian and Chukchi Seas.

4. Effects of persistent organic pollutants on polar bears in Svalbard

The study covers many areas of ecotoxicology research on polar bears. Monitoring of POP levels and studies of effects on endocrine disruption, immune system, reproduction, and demography are all parts of the study.

5. Study of influence of land-based sources of radionuclides on radioactive contamination of Kara sea through Ob- and Yenisey river systems

To assess potential levels of radionuclides input into the Kara sea from existing and potential sources of technogenic radioactivity, located on the land in the Ob- and Yenisey rivers watersheds. Specific Objectives * To reveal and estimate a) most hazardous technogenic sources of radioactive contamination in the Ob- and Yenisey watersheds and b) the most possible and dangerous natural and technogenic (antrophogenic) situations (in the regions of these sources) that may result in release of radionuclides into the environment and may lead to significant changes in the radioactive contamination of the Kara sea * To estimate parameters of radionuclides (potential amount, composition, types etc.) under release to the environment from chosen sources as a result of accidents as well as during migration from the sources to the Kara sea through river systems * To set up a dedicated Database and a Geographic Information System (GIS) for modelling transport of radionuclides from the land-based sources to the Kara sea * To develop and create a dedicated model tool for simulation of radionuclides transport from land-based sources through Ob- and Yenisey river systems to the Kara sea

6. 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.

7. Polar Exchange at the Sea Surface (POLES)

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.

8. The Role of Polar Oceans in Contemporary Climate Change

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.
