"If we continue like we are now, we could see some ecological shifts," Barth said. "It all depends on what happens with the warming and the greenhouse gases." Dead zones in other places around the country, such as Hood Canal in Washington and the Mississippi River Delta off Louisiana are caused by agricultural runoff fueling blooms of algae that rot and deplete the oxygen, said Lubchenco. But dead zones like the one off Oregon also occur off Namibia and South Africa in the Atlantic and off Peru in the Pacific.

"We're not really sure what is down the road. If it's just for a short period of time, it will not be as devastating as if it starts lasting a significant fraction of summer," she said.

Crab fishermen in Oregon and Washington are finding dead crabs in their pots, and deeper water fish, such as ling cod, wolf eels and rockfish, are showing up in Oregon tide pools, apparently chased to shore by the dead zone advancing across the Continental Shelf, said Lubchenco.

In Washington, dead fish and crabs are also being spotted on the beach along the Olympic Coast National Marine Sanctuary and the Quinault Indian Reservation, Liam Antrim, resource protection specialist for the marine reserve, said from Port Angeles, Wash.

"Last year we did some routine monitoring along six transects every other week. We never documented low oxygen conditions low enough to kill things," Antrim said. "This year we have."
