579 thumbnail picture
A lead through the ice pack with different types of ice as seen from a helicopter. Whether the dark streak is open water or grease ice is indeterminate. New and young ice is forming.
Alaska, Beaufort Sea 2007 April 1
580 thumbnail picture
Hummocky ice, what appear to be refrozen icicles but probably caused by wind effects, rough surface caused by wind ablation, and other structures in multi-year ice.

581 thumbnail picture
Hummocky ice, remnants of ridges, and various wind, water, and freezing patterns captured in the surface expression of multi-year ice.
Alaska, Beaufort Sea 2007 April 1
582 thumbnail picture
Frozen melt ponds , a linear feature indicating fractured ice, and a variety of other features are seen on this multi-year ice. The patterns are not easy to discern because of snow cover.

Parallel ridges with huge blocks of blue green ice thrown up. Like the subduction zones of plate tectonics that build mountain ranges, these features are the result of buckling caused by the great pressure of colliding ice floes. Probably second year ice.
