The Atlantic meridional overturning circulation (MOC)—a deep-ocean process that plays a critical role in regulating Earth’s climate—is primarily driven by cooling waters west of Europe, finds a new international study published Feb. 1 in Science.
Far below the ocean floor, sediments are teeming with bizarre zombie-like microbes. Although they’re technically alive, they grow in slow motion, and can take decades for a single cell to divide—something their cousins at the surface do in a matter of minutes. A new study from the Woods Hole Oceanographic Institution (WHOI) is beginning to pick apart how they survive by examining their source of “food”—nearby molecules of organic carbon. The study helps further our understanding of the limitations of life on Earth and could help inform how life might exist on other planets.
New research by the Woods Hole Oceanographic Institution (WHOI) and colleagues reveals the previously unknown behaviors of juvenile Emperor penguins in their critical early months when they leave their birth colony and first learn how to swim, dive, and find food.
The ocean has a long memory. When the water in today’s deep Pacific Ocean last saw sunlight, Charlemagne was the Holy Roman Emperor, the Song Dynasty ruled China and Oxford University had just held its very first class. During that time, between the 9th and 12th centuries, the earth’s climate was generally warmer before the cold of the Little Ice Age settled in around the 16th century. Now ocean surface temperatures are back on the rise but the question is, do the deepest parts of the ocean know that?
Sea levels are rising globally from ocean warming and melting of land ice, but the seas aren’t rising at the same rate everywhere. Sea levels have risen significantly faster in some U.S. East Coast regions compared to others. A new study led by the Woods Hole Oceanographic Institution (WHOI) reveals why.
In humans, different social groups, cities, or regions often have distinct accents and dialects. Those vocal traits are not unique to us, however. A new study from the Woods Hole Oceanographic Institution (WHOI) has found that short-finned pilot whales living off the coast of Hawai’i have their own sorts of vocal dialects, a discovery that may help researchers understand the whales’ complex social structure.
Researchers found that the soundscape of a reef—the combined sounds of all animals living nearby—might play a major role in steering corals towards healthy reef systems and away from damaged ones.
Surface melting across Greenland’s mile-thick ice sheet began increasing in the mid-19th century and then ramped up dramatically during the 20th and early 21st centuries, showing no signs of abating, according to new research published Dec. 5, 2018, in the journal Nature. The study provides new evidence of the impacts of climate change on Arctic melting and global sea level rise.
In the late 1980s, more than three-quarters of the winter flounder caught in Boston Harbor—one of the most polluted harbors in America—showed signs of liver disease, many of them with cancerous tumors. But now, a scientist at Woods Hole Oceanographic Institution (WHOI) has documented a dramatic rebound in flounder health spurred by decades of remediation efforts.
Alvin, the country's only deep-diving research submersible capable of carrying humans to the sea floor, reached another milestone in its long career on Nov. 26, 2018, when the sub made its 5,000th dive during an expedition to the Guaymas Basin in the Gulf of California.
More than 4,000 years ago, the Harappa culture thrived in the Indus River Valley of what is now modern Pakistan and northwestern India, where they built sophisticated cities, invented sewage systems that predated ancient Rome’s, and engaged in long-distance trade with settlements in Mesopotamia. Yet by 1800 BCE, this advanced culture had abandoned their cities, moving instead to smaller villages in the Himalayan foothills. A new study from the Woods Hole Oceanographic Institution (WHOI) found evidence that climate change likely drove the Harappans to resettle far away from the floodplains of the Indus.
A new study from the Woods Hole Oceanographic Institution (WHOI) has uncovered the history of bleaching on a coral reef in the epicenter of El Nino, revealing how some corals have been able to return after facing extreme conditions. The study was published October 26, 2018, in the journal Communications Biology.
A new system using next-generation robotic sensors to monitor coastal waters for disease-causing microalgae has been funded by the NOAA Sea Grant Program as part of a national strategic investment in aquaculture.
A new model predicts that Atlantic sea scallop fisheries may potentially be in danger. As levels of carbon dioxide increase in the Earth’s atmosphere, the upper oceans become increasingly acidic—a condition that could reduce the sea scallop population by more than 50% in the next 30 to 80 years, under a worst-case scenario.
