Investigation of the Arctic Internal Wave Field. Small-Scale Processes in the Arctic Ocean and Sub-Arctic Seas.

The unprecedented subsurface velocity record from the AEDB as it drifted from the Nansen Basin, over the Yermak Plateau, and into the Greenland Sea provided new insights into the high latitude internal wave field. Plueddemann (1992) showed that the wave field over the Yermak Plateau was dominated by...
