Oceans around the world are beset by marine heatwaves, pollution, coral bleaching, mass die-offs and overfishing. Along the West Coast, kelp, which captures a lot of carbon dioxide, is dying off. In other areas, like the Gulf of Mexico, there has been ...

The rate of plastic entering the oceans could accelerate 2.6 times by 2040 if left unchecked, say researchers.

Coastal communities are exposed to coastal water pollution even without entering polluted waters, researchers find.

Antarctica's "Doomsday Glacier" -- nicknamed because its collapse could drive catastrophic sea level rise -- is melting rapidly in unexpected ways, according to new research.

Scientists have known for years that the Arctic is warming faster than the rest of the world—nearly four times faster, according to a recent study. Tracking that warming is critical to understanding climate change not just in the Arctic but around the ...

ATLANTIC CITY, N.J. (AP) — Federal environmental and energy officials moved Wednesday to quell a growing controversy over whether work done by the offshore wind power industry is killing whales in the northeastern U.S., saying there is no evidence this...

The Alaska snow crab harvest has been canceled for the first time ever after billions of the crustaceans have disappeared from the cold, treacherous waters of the Bering Sea in recent years.

The oyster reefs help protect the state’s coasts from extreme weather.

A globe-spanning study published Thursday outlines new, potentially unexpected threats to ocean ecosystems and vulnerable coastal communities within the next five to 10 years that will come on top of the already harmful effects of overfishing, pollutio...

The Earth has already warmed more than 1 degree Celsius. New research suggests that above 1.5 degrees, massive ice melt, ocean current disruptions and coral die-offs are likely.

A new climate report card paints a grim future if emissions aren't reduced: "Climate change is rewiring marine ecosystems at an alarming rate."

A field glaciologist explains the changes scientists are now seeing.

Marine sponges perform a slow, sneeze-like move to get rid of mucus, which offers a meal to nearby fish.

North Atlantic right whales are threatened by entanglements in fishing gear and often don't survive.

A new model suggests “mantle rain” from inside Earth’s mantle ensures we will always have a surface ocean.

The world must do more to stop the dramatic decline in ocean health, UN Secretary-General António Guterres said on Sunday, urging young people gathered in Carcavelos, Portugal, for a UN Youth and Innovation Forum to step up because his generation’s lea...

The marine treasures of Colombia are often overlooked, as the country is known more for its mountains and the colourful towns that dot its coffee region. But just below the waves, a vibrant undersea world with over a thousand square kilometres of coral...

Coastal flooding could increase faster than expected if subsidence isn't factored into models along with sea level rise.

Genetic testing has determined a single 4,500-year-old seagrass may have spread over 200 sq km of underwater seafloor – about 20,000 football fields

Billion-dollar seawalls often won’t be an affordable long-term answer to rising seas, and better alternatives exist.

Researchers have long suspected that an ingredient in sunscreen called oxybenzone was harming corals, but no one knew how. A new study shows how corals turn oxybenzone into a sunlight-activated toxin.

Liquid water below the ice determines how fast an ice stream flows. As the ice sheet gets thinner, more of that salty groundwater could rise.
