A new report shows a dire situation for salmon in Washington State. Populations are reeling from habitat loss, flooding and the repercussions of climate change.

A new study of the closest ancient analog to modern carbon emissions finds that massive volcanism was the main cause of high carbon at the time. But nature did not come close to matching what humans are doing today.

A recent study sheds light on how different types of species are affected by calving icebergs that tear apart the seafloor.

In a new survey of the sub-seafloor off the U.S. Northeast coast, scientists have made a surprising discovery: a gigantic aquifer of relatively fresh water trapped in porous sediments lying below the salty ocean.

A video reveals mature jellyfish under the Arctic sea ice, where they aren’t supposed to be.

Computer scientists at Columbia University will work with oceanographers to understand what has caused an unusual plankton-like species to rapidly invade the Arabian Sea food chain, threatening fisheries that sustain more than 100 million people.

The creation of the narrow isthmus that joins North and South America changed not just the world map, but the circulation of oceans, the course of biologic evolution, and probably global climate. Scientists try to decipher the story behind its formation.

Can mushrooms help clean up oil spills? Can oysters filter sewage pollution? Industrial waste is being injected into the planet’s soil and water as a result of human activity. Pioneers in the field of conservation and sustainability are employing nature’s own biological task force to help clean up.
