Since May, hundreds of dead and dying seabirds have been found across the northern Bering and southern Chukchi Seas.
The National Park Service and U.S. Fish and Wildlife Service have labeled the event a die-off and are coordinating monitoring efforts with local communities.
"These birds have been starving," said wildlife biolgoist Kathy Kuletz of USFWS. "They're very emaciated. Their muscles have atrophied."
