Oceanic Dead Zones Are Worse Than Ever

Climate change is supercharging the creation of low-oxygen zones in the planet's oceans, with concerning implications for wildlife and fisheries.

The Oregon coast is known for its stunning beauty. But under the surface, these cold ocean currents support one of the most productive ecosystems on the planet — and because of that, one of the largest fishing fleets on the west coast.  

"Our family fishing boat, the Timmy Boy, has just come in from a trip fishing for sablefish," says fisherman Bob Eder. "And we found some!"

Eder says this abundant source of seafood is fueled by the seasonal upwelling of cold, nutrient-rich water along the coast.
