The Effects of Time-Dependent Winds and Ocean Eddies on Ice Motion in a Marginal Ice Zone.
Observations made during the MIZEX program indicate the presence of mesoscale eddies in the ocean front at the marginal ice edge in the East Greenland Current. The eddies ranged in scale from 5 to 80 km. Barotropic and baroclinic instability may be the physical mechanisms responsible for the existan...
