Some 390 million years ago in the ancient ocean, marine animals began colonizing depths previously uninhabited. New research indicates this underwater migration occurred in response to a permanent ...

Oceans represent 97 percent of the physical habitable space we have on this planet – and the oceans are central to sustaining all life on Earth. Since 2000, considerable effort has been directed at ...

The eastern tropical Pacific Ocean is known for its large low-oxygen zones that are increasing in size, putting marine life at risk. New research shows that 15 million years ago, the opposite was true ...

Climate change is extending far beyond the threat of melting polar ice caps -- it's putting a dangerous stranglehold on life in oceans, too. A new study published in the science journal Nature ...

Rising deep-ocean oxygen levels likely opened up new marine habitats and spurred speciation among early vertebrates, according to a new study in the Proceedings of the National Academy of Sciences.

The new study by the American Geophysical Union is lying buried behind a paywall, but the facts it covers aren’t in dispute. Low oxygen areas in the deep ocean waters are spreading, and that low ...

Freshwater ecosystems have spent years under growing pressure from pollution, changing weather patterns and rising ...

Could the artificial introduction of oxygen revitalise dying coastal waters? While oxygenation approaches have already been proven successful in lakes, their potential side effects must be carefully ...

Rather than ocean oxygen levels improving as they usually do this time of year, hypoxia off the Pacific Northwest coast is as bad as it’s been at any point in 2021, according to collaborative research ...
