The high latitude oceans in the climate system, with special emphasis on their role in the global carbon cycle

Updated 2000-06-22

The scientific objectives of this project is to add information that helps elucidate the role of the Arctic Mediterranean Seas (Arctic Ocean and Nordic Seas) in the climatic system of the Northern Europe. More specifically it has the following aims: - To assess the heat and carbon dioxide fluxes over the air-sea interface in the Barents Sea and elucidate the effect this has on the formation of Arctic Ocean intermediate waters and associated carbon fluxes. - To assess the temporal variability of the fresh water distribution in the Arctic Ocean, both river runoff and sea ice melt, and the affect this has on the outflow of fresh water to the regions of open ocean deep water formation (the Greenland, Iceland and Labrador Seas). - To assess the mixing of upper and intermediate waters along the East Greenland Current that gives the properties of the overflow into the North Atlantic Ocean and thus add to the driving of the thermohaline circulation. This also contributes to the sequestering of anthropogenic carbon dioxide.

This is not a National Implementation Plan (NIP) project
