Laidre fjords 1.JPG (IMAGE) University of Washington Caption A Southeast Greenland fjord is covered in fast ice, or sea ice that is connected to the coast, for about four months of the year, between February and late May. This photo was taken in April 2016. The open water seen on the horizon confines these polar bears, believed to be a 20th subpopulation, to a small region along the coast.
