Spewing too much carbon dioxide into the atmosphere could shut down the major ocean current that ferries warm water to the North Atlantic, new climate simulations suggest. While not as extreme as the doomsday scenario portrayed in the movie The Day After Tomorrow, such a shutdown could cause wi...
President Obama will expand the Papahānaumokuākea Marine National Monument off the coast of Hawaii, creating the world’s largest marine protected area. Building on the United States’ global leadership in marine conservation, today’s designation will more than quadruple the size of the existing marin...
Dear Politicians and Elected Officials,
Our oceans are in peril. There is too much plastic in them. Plastic suffocates and strangles marine wildlife who consume it, thinking it is food.
The oceans have far too many chemicals in them; recklessly dumped with abandon.
We have r...
Antarctic sea ice is constantly on the move as powerful winds blow it away from the coast and out toward the open ocean. A new study shows how that ice migration may be more important for the global ocean circulation than anyone realized.
A team of scientists used a computer model to synthesize mil...

New research published this week reveals that vast stretches of the ocean interior abruptly lost...
Human influence on the climate system is clear and growing, with impacts observed on all continents. If left unchecked, climate change will increase the likelihood of severe, pervasive and irreversible impacts for people and ecosystems. However, options are available to adapt to climate change and i...
There have been five mass extinction events in Earth's history. In the worst one, 250 million years ago, 96 percent of marine species and 70 percent of land species died off. It took millions of years to recover.
Nowadays, many scientists are predicting that we're on track for a sixth mass extincti...

Global warming is likely playing a bigger role than previously thought in dead zones in oceans, lakes and rivers around the world and it's only going to get worse, according to a new study.
Dead zones occur when fertilizer runoff clogs waterways with nutrients, such as nitrogen and phosphor...
Interview with David McGuire, Founder of Shark Stewards
Emmy-award-winning filmmaker and marine scientist David McGuire has not only swum with sharks, he’s swum FOR them. As founder and executive director of the Sausalito-based marine research and advocacy organization Sea Stewards, McGuire started...
A NOAA-led research team has found the first evidence that acidity of continental shelf waters off the West Coast is dissolving the shells of tiny free-swimming marine snails, called pteropods, which provide food for pink salmon, mackerel and herring, according to a new paper published in Proce...
There's more plastic floating around the ocean than any other type of marine debris—that we know. What's harder to figure out is just how much is out there. A recent survey of marine plastic debris found something surprising: Nearly 99% of it was missing.
"We were expecting values in excess of one ...

With his jaw-dropping footage of amazing sea creatures, oceanographer David Gallo strikes us with wonder and exposes how little we know about what lies below the surface of the ocean. The ocean is the planet's largest habitat, covering more than three-quarters of its surface, yet most...
About 55.5 million years ago, geologically rapid emission of a large volume of greenhouse gases at the Paleocene-Eocene boundary (PETM) led to global warming of about 5oC, severe ocean acidification, and widespread extinction of microscopic organisms living on the deep-sea floor (foraminifera).
A s...
When President Barack Obama convenes his cabinet in the White House’s Roosevelt Room, one might be left with the impression that defenders of our oceans are rather pointedly underrepresented. The Department of Commerce, which oversees the National Oceanic and Atmospheric Administration, or NOAA, has...
