Pacific walruses have come ashore on the northwest coast of Alaska in what has become an annual sign of the effects of climate change.
"There appears to be several thousand animals up there," said Andrea Medeiros, spokeswoman for the U.S. Fish and Wildlife Service in Anchorage.
Images of the walruses were captured by a photographer not affiliated with the agency near Point Lay, an Inupiat Eskimo village 700 miles northwest of Anchorage and 300 miles southwest of Barrow.
Walruses have been coming to shore on the U.S. side of the Chukchi Sea in large numbers for about eight years. They also come to shore on the Russian side.
Researchers say it's likely a result of less sea ice brought on by climate warming.
Walruses dive to feed on clams, sea snails and other food on the ocean bottom but cannot swim indefinitely.
Many male walruses never leave the Bering Sea but females, especially mothers with pups, ride the edge of the sea ice as it moves north in summer through the Bering Strait and into the Arctic Ocean. They use sea ice as a platform from which to dive for food while pups rest on the ice.
In recent years, sea ice has receded north beyond shallow continental shelf waters and over water that exceeds 2 miles deep, beyond the diving range of an adult walrus.
Walruses in large numbers were first spotted on the U.S. side of the Chukchi Sea in 2007. They returned in 2009, and in 2011, scientists estimated 30,000 walruses along 1 kilometer of beach near Point Lay.
Last year, an estimated 35,000 walruses were photographed 5 miles north of Point Lay.
The agency and two others have issued an appeal to stay away from large gatherings of walruses that come ashore. Young animals are vulnerable to stampedes when a group gathers nearly shoulder-to-shoulder on a beach.
Stampedes can be triggered by a polar bear, human or low-flying airplane.
With this year's low summer sea ice, it's not surprising to see walruses on shore looking for a place to rest, Margaret Williams of the World Wildlife Fund in Anchorage said in a statement. The sharp decline of Arctic sea ice over the last decade is leading to major changes for wildlife and communities.
"Such extreme events are a stark reminder of the urgent need to ratchet down the emissions that are warming our planet," Williams said.

    Walruses leave the water and come to shore as a result of less sea ice brought on by climate warming. In addition however, specifically mother walruses, climb on the ice to use it as a platform in order to dive for food while their babies rest and stay on the ice. I find it amazing and very interesting how just the climate can change and affect the way the wildlife acts.

    Walruses typically come to shore as a result of climate warming. Mother walruses however, use the ice as a platform to dive off of. While shes underwater hunting for food the baby walrus can sit and rest.

    The mother rest on the ice with her babies. The ice is a platform for the dad to dive off and hunt food

    so they can either raise there famalies or so that they can sleep and have a place away from prey

    to cool off and sleep, and to get there pups some food.

    They can't stay under the water very long. They need to take a little break for a little bit.

    My hypothesis is that the walrus's come up onto shore to get warm or take a break from swimming. I would wonder why they would come up onto ice to get warm? Also more sea ice is melting, resulting in them being driven to the shore.

    I think they come on to shore or climb up on the ice because, they want to take a break from swimming and to get warm. Also, more sea ice is melting, which is making them go onto shore.

    To rest or dive for food.

    The walrus' come to shore to find a place to rest.
