The role of the Canadian Arctic Archipelago in the Arctic freshwater cycle.
The freshwater outflow (liquid and sea ice) from the Arctic Ocean into the North Atlantic through the Canadian Arctic Archipelago (CAA) is an important component of the Arctic freshwater cycle. Changes in the freshwater export of the CAA could affect the deep water formation, which has great impact...
