Review of air-ice-ocean processes in the Margial Ice Zone of importance for offshore activities in the Barents Sea region
In this report we have reviewed air-ice-ocean processes in the Marginal Ice Zone (MIZ) of importance for offshore operations and related environmental issues. The MIZ is a characteristic feature of the circumpolar Arctic and sub-Arctic seas, i.e., the European, Russian, US and Canadian parts of the...

In this report we have reviewed air-ice-ocean processes in the Marginal Ice Zone (MIZ) of importance for offshore operations and related environmental issues. The MIZ is a characteristic feature of the circumpolar Arctic and sub-Arctic seas, i.e., the European, Russian, US and Canadian parts of the Arctic.

The Barents Sea is partly ice- covered in the winter season in the northern and eastern regions.
