BGEP
The Canadian Basin with its Beaufort Gyre (BG) contains about 45,000 km3 of fresh water (Aagaard and Carmack, 1989). This is the major reservoir of fresh water stored in the Arctic Ocean and its volume is 10-15 times larger than the total annual river runoff to the Arctic Ocean, and at least two times larger than the amount of fresh water stored in the sea ice. What is the mechanism of fresh water accumulation in the BG? A release of only 5% of this fresh water is enough to cause a salinity anomaly with the magnitude of the Great Salinity Anomaly of the 1970s. Summary provided by: http://www.whoi.edu/beaufortgyre/
