Sea Ice Stuck Fast
 - Sea Ice

Antarctic Mountains

A picture taken of consolidated pack-ice. The ice that you see is mainly pack-ice, last years ice that formed elsewhere, broke up and floated here. As the temperature dropped, then this ice became stuck together by fast-ice, sea-water frozen in situ and attached to the coast that acts as a glue for the loose bits of pack. The ice-bergs that you see have been frozen in position and will remain so until they are freed by the spring break-up of the surrounding sea-ice.
