Warming ocean waters are an invitation to all sorts of pathogens with the potential to remake ocean life.

California State Parks scientists are running tests this week to determine what caused about 1,500 fish to die in Malibu Lagoon last week, but officials suspect higher-than-normal water temperatures may have played a role.

Wildlife officials say populations of the silvery Pacific sardine have plummeted over the past decade.

The high temperatures might be left over from the warm-water "blob" off California in 2014.

The Pacific Ocean off the California coast is mixed up, and so are many of the animals that live there.

July 23, 2007 – Over the last five years, large, predatory Humboldt squid have moved north from equatorial waters and invaded the sea off Central California, where they may be decimating populations of Pacific hake, an important commercial fish.

Ten million scallops that have died in the waters near Qualicum Beach due to rising ocean acidity are the latest victims in a series of marine die-offs that have plagued the West Coast for 10 years. . .

An increase in carbon emissions are showing up not only in the air, but also in water. Now researchers and shellfish farmers are teaming up to see how marine plants can help stave off the effects of ocean acidification. Special correspondent Jes Burns of Oregon Public Broadcasting reports.

Ocean acidification threatens some of Alaska’s most lucrative crab fisheries. But there’s one ray of hope: it’s possible that crabs might be able to adapt to the changing oceans. The big question scientists are researching at Bob Foy’s lab in Kodiak is – will they have enough time?
