Assessing the Western Arctic Boundary Current and its role in the Arctic ecosystem and climate change

The Western Arctic Boundary Current, which flows out of Barrow Canyon onto the continental slope of the Beaufort Sea. A multi-disciplinary mooring is located at 152o W in the center of the current, and is maintained as part of the Arctic Observing Network (AON). The AON mooring measures the physical properties of the boundary current (temperature, salinity, turbidity, velocity, ice thickness, ice velocity, bottom pressure), chemical properties (dissolved oxygen, pH, nitrate, pCO2), and biological properties (chlorophyll fluorescence, marine mammal calls). The shipboard transects will consist of conductivity/temperature/depth (CTD) measurements, and water samples for measuring water chemistry. The ship's acoustic Doppler current profiler (ADCP) will measure the velocity of the water along the cruise track, and atmospheric variables will be measured using the ship's meteorological sensors.
