Extended Measurements in Bering Strait and the Variable Outflow from the Chukchi Shelf to the Arctic Ocean and an Extended Analysis of Time Series and Hydrographic Data with Reference to Shelf-Basin Interactions
LONG-TERM GOALS. Our long-term research goals are to understand the circulation and physical properties of the high latitude ocean, both quantitatively and mechanistically. We also seek to understand the effects of physical processes in the ocean on the ice cover, biology, and chemistry of the marin...

LONG-TERM GOALS. Our long-term research goals are to understand the circulation and physical properties of the high latitude ocean, both quantitatively and mechanistically.
