Ice melting off Antarctica coast - February 19th, 2009

Ice forming off the coast of Antarctica (left) creates swirled patterns in the nearby waters. (Please click here to see a radar image of a similar phenomenon).

Sea ice may melt during the warmer periods but reform in new patterns as colder periods return. As the ice forms, the area of new growth sometimes has swirl patterns caused by eddy-current circulation.

In water flow, an eddy-current is a current that moves in the opposite direction of the normal flow.

The clouds over the area also present some interesting wavelike patterns (upper right).
