  • Seafloor hosts surprising number of deep-sea vents

    The ocean bottom is deep and dark, but far from lifeless. New research shows that it teems with far more oases of life than anyone had imagined.

    Earth’s surface rock (and the soil or sand above it) moves slowly atop shifting rocky slabs known as tectonic plates. Deep along the sunless seafloor, some of those tectonic plates pull apart. Near these plate boundaries, seawater seeps down and...

  • Last year’s strong El Niño is gone. Next up: La Niña

    Every few years, the world’s weather is thrown off balance. It happens when surface waters near the equator in the eastern and central Pacific Ocean warm up just a fraction of a degree. Afterward, some regions experience heavier rainfall than normal — and flooding. Others will battle drought and wildfires. Still others might have to contend with ice storms and other extreme weather. This...

  • Catching ‘Dory’ fish can poison entire coral reef ecosystems

    The popularity of animated kids’ movies — Finding Nemo and its new sequel, Finding Dory — could spell doom for many coral reef communities, a new study warns. But even without families trying to bring home the types of fish portrayed in these films, coral-reef species are in trouble. The aquarium industry has been harvesting fish as pets. And more than half of the saltwater fish sold as U.S....

  • Polar bears swim for days as sea ice retreats

    Polar bears are excellent long-distance swimmers. Some can travel for days at a time, with only very short rest stops on ice flows. But even polar bears have their limits. Now a study finds they are swimming longer distances in years with the least amount of Arctic sea ice. And that worries Arctic researchers.

    Swimming a long time in cold water takes a lot of energy. Polar bears can tire...

  • Not so sweet: Fake sugar found at sea

    Fake sweeteners may seem like a good calorie-saving substitute for sugar. But researchers in Europe have now found traces of one of these sweeteners at five sites in the North Sea. That might be a problem, they warn. What makes the fake sugar helpful for waistlines, they say, could be bad for the environment.

    This is one of the first studies to show that artificial sweeteners can end up...

  • Diving deep into history

    Cindy Van Dover knows a lot about the deep oceans. But she never expected to find a shipwreck more than 200 years old while she was hunting for sea creatures.

    It was July 2015. Van Dover and other deep-sea biologists were cruising on a research ship off the coast of North Carolina. They were looking for a scientific mooring — a cable attached to the ocean floor more than 1.6 kilometers (...

  • Gulf oil spills could destroy shipwrecks faster

    NEW ORLEANS, La. — In April 2010, an explosion at the Deepwater Horizon drilling platform caused a huge oil spill in the Gulf of Mexico. Leftover oil from that spill still pollutes the Gulf. And that oil could be speeding up the destruction of old shipwrecks there, data now suggest.

    Corrosion is a type of chemical reaction that can weaken — and ultimately destroy — metal structures....

  • Sea level rising fastest in 2,800 years

    Sea levels rose faster during the 20th century than at any time during in the previous 2,800 years, a new study shows. That means the oceans haven’t risen this quickly since the founding of ancient Rome.

    Researchers calculated how global sea levels have risen and fallen in the past. Throughout the 1900s, the oceans on average rose by some 13.8 centimeters (5.4 inches). More than half of ...

  • What a drag! Fishing gear’s effects on whales

    Whales that get tangled up in fishing lines and other gear can be stuck towing it around for months or years. And it’s not pleasant. Those lines can cut into the mammals’ flesh. Some whales will die from their injuries. But how does it actually feel to be carrying all that trash around? Researchers at the Woods Hole Oceanographic Institution, or WHOI, on the Massachusetts coast wanted to know...

  • Arctic ice travels fast, carrying pollution

    SAN FRANCISCO, Calif. — Climate change could turn the Arctic Ocean into a high-speed ice superhighway. Chunks of sea ice in the Arctic are becoming thinner as old ice melts. The new ice that’s replacing it travels farther and faster than the older ice had. And as the younger ice travels, it carries dirt, organisms and pollution along for the ride, new research shows.

    Researchers have...
