Directory entires that have specified White 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. The Arctic sea ice ecosystem in recent environmental changes

Biological materials obtained in the central Arctic Ocean at the FSU “North Pole stations” in 1975-1981 have shown that the multi-year ice and ice/water interface is of rich and diverse biotop inhabited by the large number of diatoms and invertebrate animals. Two main matter fluxes in the sea ice ecosystem may be distinguished: (1) the inflow of biogenous elements from water into the ice interior where they are assimilated by the microflora during photosynthesis (summer stage), and (2) the outflow – from ice to water - of the organic matter accumulated in the summer due to photosynthesis (winter stage). Accumulation of organic matter within the sea ice interior during the process of photosynthesis may be considered as an energy depot for organisms of the whole trophic network of the arctic sea ice ecosystem. Recent data from the SHEBA Ice Camp drifted within the Beaufort Gyre 1997-1998 have shown that: (1) sea ice diatoms are very scarce by species and numbers; (2) fresh water green algae are dominated by numbers and distributed within the whole sea ice thickness; (3) invertebrate animals within the sea ice interior are not indicated; (4) invertebrate animals from the ice/water interface are scarce by species and numbers; (5) concentrations of chlorophyll and nutrients in the sea ice are significantly lower of the average concentrations measured before in this region for the same period of time. Remarkable accumulation of the organic mater within the sea ice interior were not indicated.

4. An integrated assessment of environmental and socio-economic aspects for the coastal zone of the sub-arctic White Sea and Arctic Pechora Sea

The aim of the study is to make a first integrated assessment of environmental and socio-economic aspects of the northern Russian coastal region, in this case the sub-Arctic White Sea and Arctic Pechora Sea, on the basis of 1) the present state of the coastal environment, as based on the results of INTAS project 94-391, and 2) the sociocultural and economic significance of those regions, and the present and potential conflict situations between, and developmental potentials of, environmental and local socio-economic aspects. Research activities: Inventory and literature search on socio-economic and environmental aspects in White Sea, southern Barents Sea and Pechora Sea.

5. Biodiversity and adaptation strategies of Arctic coastal marine benthos

The objectives of the project are to assess: 1) the present biodiversity of benthos in Arctic coastal ecosystems (White Sea, southern Barents Sea, Pechora Sea), and indicators for changes caused by disturbances; 2) the adaptations to the Arctic climate for some benthic key-species, the additional influence of disturbance and the sensitivity of the key-species to additional stress from disturbances; 3) the geochemical background of the regions Research activities: Annual missions by ship for sampling water, sediments and macrobenthos. Biodiversity analysis of macrobenthos in sediments in laboratories in Murmansk (MMBI) and Tromsø (Akvaplan-Niva), ecophysiological analyses in laboratories of St. Petersburg (ZISP), Yerseke (NIOO-CEMO) and Pisa (UN), analyses of pollutants in laboratories in Moscow (MSU), Nantes(UN) and Pisa (UP), geochemical analyses of water and sediment in laboratories of Moscow (MSU) and Barcelona (UB).
