But there's a gaping hole in that news: Schwing said the population of krill has mysteriously crashed in the ocean.
This zooplankton, which resembles a tiny shrimp, is a key salmon food.
Several bird species that depend on krill have also crashed, Schwing said, such as the Cassin's auklet, a seabird that nests on the Farallone Islands.
Also, whales that normally gorge on krill shifted to eating fish.
"Historically there's a strong relationship between abundance of krill and the amount of upwelling that occurs," said Schwing.
Although large bodies of oxygen-poor water far offshore are normal, the rapid expansion of these waters is not.
And scientists link it, in part, to climate change, Schwing said.
