The absence of vast swaths of summer sea ice is changing the behavior of Pacific walrus, federal scientists said Wednesday, but added that more research will be needed to say what the final effects might be.
Tens of thousands of walruses have come ashore in northwest Alaska because the sea ice they normally rest on has melted.
"for one mile or more. This is just packed shoulder-to-shoulder," U.S. Geological Survey biologist Anthony Fischbach said in a telephone interview from Alaska.
Fischbach said scientists don't know how long the walrus camp-out will last, but there should be enough food for all of them.
