Overview of the ecosystem
The Barents Sea is a sub-Arctic ecosystem located between 70 and 80ºN. It connects with the Norwegian Sea to the west and the Arctic Ocean to the north. The average depth is 230 m and the maximum depth is approximately 500 m at the western entrance. The general pattern of circulation (Figure 2.1.1) is strongly influenced by this topography, and is characterised by inflow of relatively warm Atlanti...
Introduction
To ensure the comparability of observation results and to estimate seasonal and year-to year variations in oceanographic variables, it was suggested in Stockholm as early as 1899 that measurements should be made at standard depths and on standard sections. At the beginning of the 20th century observations started on the Kola Section in the Barents Sea (Knipovich 1906), and by the 1930s, a network...
Overview of abiotic compontents - Overview of climate
The distinctive feature of the atmospheric circulation was an intensification of the Arctic anticyclone during spring and summer, which caused a southward shift of Atlantic cyclone tracks and prevalence of northerly and easterly winds over the Barents Sea.
The Atlantic Water temperature was higher than the average throughout the year of 2008, but colder than in the previous two years. The positive ...
Issues of importance for ecosystem based management (introduction)
As described in the introduction (chapter Introduction ), this report will be used as a basis for developing ecosystem based management in the Barents Sea. The report is intended to establish the status for the entire Barents Sea ecosystem. It forms an information basis for establishing a management plan for the Russian part of the ecosystem and provide support for further developing the ecosystem b...

The BarentsPortal is a project implemented under the Joint Norwegian-Russian Commission on Environmental Protection. The Portal is a joint Norwegian - Russian instrument designed for the mutual exchange and presentation of information and environmental data relevant to the management of the Barents Sea. It is intended to serve as the future tool for updating of the recently published Norwegian - Russian environmental status report (published here), and for further cooperation on ecosystem-based management of the Barents Sea.Ministry of the Environment
