Summary:

Excess carbon dioxide in the atmosphere is making the oceans more acidic. Some studies show that's bad news for fish, including commercially important species. But a new study shows that herring might be able to tolerate this change.

These strange-looking floating objects are really giant plastic test tubes called KOSMOS mesocosms that extend roughly 19 metres deep. Researchers used them to test the response of young herring to ocean acidification.

Summary:

Ocean conditions off most of the US West Coast are returning roughly to average, after an extreme marine heat wave from about 2014 to 2016 disrupted the California Current Ecosystem and shifted many species beyond their traditional range, according to a new report from NOAA Fisheries' two marine laboratories on the West Coast. Some warm waters remain off the Pacific Northwest, however.
