Researchers have created a map of oceanic 'dead zones' that existed during the Pliocene epoch, when the Earth's climate was two to three degrees warmer than it is now. The work could provide a glimpse ...

With no dissolved oxygen to sustain animals or plants, ocean anoxic zones are areas where only microbes suited to the environment can live. “You don’t get big fish,” said UC Santa Barbara ...
