Harp seals mate and rear their young on the sea ice off the east coast of Canada in the spring and move north as the weather warms. But increasing numbers of seals are ending up stranded along the U.S. East Coast, as far south as the Carolinas, far away from where they should be at this time of year.
They start out in Canada and move north to the Carolinas.
As ice levels in the North Atlantic have declined, the number of seals that have wound up on beaches, either dead or in poor health, has increased, new research shows.
Here is the same story from 1990.
