Scientists believe the mass migration of walruses in Alaska is due to depleting sea ice. As the ocean ice melts, the walruses are forced to come ashore dry land to escape drowning. Many left the ice sooner than is typical of the creature, and some fear it is an early sign they may go extinct. The group was largely mothers and babies, and it is the largest walrus migration to land scientists have ever recorded.
This mass arrival of walruses to Alaskan shores is not the first such arrival. In 2007 and 2009, similar numbers of walruses grouped together on land due to a shortage of sea ice. Usually walruses tend to gather in groups of up to 500.
