Comparison of Water Properties and Flows in the U.S. and Russian Channels of the Bering Strait - 2005-2006
The Bering Strait throughflow is critical for the Chukchi Sea and the upper Arctic Ocean. It is important in the global freshwater cycle and influences the Atlantic overturning circulation and possibly world climate. The throughflow variability (seasonal and interannual) impacts the role of Pacific...

The Bering Strait throughflow is critical for the Chukchi Sea and the upper Arctic Ocean. It is important in the global freshwater cycle and influences the Atlantic overturning circulation and possibly world climate. The throughflow variability (seasonal and interannual) impacts the role of Pacific waters in the Arctic, especially the ventilation depth. The water properties provide valuable boundary information for Arctic and global studies, including realistic modeling of the Chukchi Sea and Arctic Ocean. The Bering Strait is divided into two channels, both with differing water properties. Although year-round moorings have been deployed in the Bering Strait region since 1990, very few simultaneous measurements of both channels exist, since the western channel (which carries the colder, saltier, higher nutrient water) lies within the Russian Exclusive Economic Zone (EEZ). At the start of this grant, there were only three years of records from the western channel. To counter this lack of data, a mooring site had been established north of the strait, where the sea-floor topography diverts the western channel flow into the U.S.-EEZ for a short distance. The hypothesis is that this mooring captures a useful average of the flow through both channels of the strait. However, prior to this grant, only one year of insitu data was available for comparison. In early 2005, it became clear that in summer 2005, a continuation of a joint National Oceanic and Atmospheric Administration (NOAA) -Russian program would deploy three moorings in the western (Russian) channel, giving the best-ever coverage of the western channel.
