When scientists discovered a hydrothermal vent site in the Arctic Ocean’s Aurora hydrothermal system in 2014, they did not immediately realize just how exciting their discovery was.
Read MoreMarine Protected Areas in Antarctica should include young emperor penguins, scientists say
Scientists at the Woods Hole Oceanographic Institution (WHOI) and European research institutions are calling for better protections for juvenile emperor penguins, as the U.S. Fish and Wildlife Service considers listing the species under the Endangered Species Act and the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) considers expanding the network of Marine Protected Areas (MPAs) in the Southern Ocean.
Read MoreAtlantic Ocean Circulation at Weakest Point in 1,600 years
Atlantic Ocean Circulation at Weakest Point in More Than 1500 years New research led by University College London (UCL) and Woods Hole Oceanographic Institution (WHOI) provides evidence that a key cog in the global ocean circulation system hasn’t been running at peak strength since the mid-1800s and is currently at its weakest point in the past 1,600 years. If the system continues to weaken, it could disrupt weather patterns from the United States and Europe to the African Sahel, and cause more rapid increase in sea level on the U.S. East Coast.
Read MoreScientists Find Surprising Evidence of Rapid Changes in the Arctic
Scientists have found surprising evidence of rapid climate change in the Arctic: In the middle of the Arctic Ocean near the North Pole, they discovered that the levels of radium-228 have almost doubled over the last decade.
Read MoreAntarctic Bottom Waters Freshening at Unexpected Rate
In the cold depths along the sea floor, Antarctic Bottom Waters are part of a critical part of the global circulatory system. Over the last decade, scientists have been monitoring changes in these waters, but a new WHOI study suggests these changes are themselves shifting in unexpected ways, with potentially significant consequences for the ocean and climate.

Ocean currents, in concert with the atmosphere, play a critical role in regulating Earth’s climate. Yet the complexities of how water is moved around the globe and how the strength…
Read MoreSurprising Return of North Atlantic Circulation Pump
One of the “pumps” contributing to the ocean’s global circulation suddenly switched on again last winter for the first time this decade, scientists reported Tuesday (Dec. 23) in Nature Geoscience.…
Read MoreGeologists Discover Signs of Volcanoes Blowing their Tops in the Deep Ocean
A WHOI research team has uncovered evidence of explosive volcanic eruptions deep beneath the ice-covered surface of the Arctic Ocean. Such violent eruptions of splintered, fragmented rock?known as pyroclastic deposits?were not thought possible at great ocean depths because of the intense weight and pressure of water and because of the composition of seafloor magma and rock.

Bone-chilling temperatures, biting winds, and rapidly changing sea ice conditions make the Chukchi Sea off Point Barrow, Alaska, a particularly challenging place to work. And then there are the curious…

Researchers will probe the Gakkel Ridge during expedition that begins on July 1.
Read MoreRapid Sea Level Rise in the Arctic Ocean May Alter Views of Human Migration
Scientists have found new evidence that the Bering Strait near Alaska flooded into the Arctic Ocean about 11,000 years ago, about 1,000 years earlier than widely believed, closing off the…
Read MoreBouncing Among the Arctic Ice: The Ultimate Arctic Machine?
WHOI scientists exploring the largely unknown currents beneath the polar sea ice have designed and successfully tested a new float that drifts at various depths through the oceans measuring water…
Read MoreSalty Staircase in the Atlantic Provides Clues to Ocean Mixing
Layers of salty ocean water mix with layers of fresher water, creating a salty staircase or layering driven by small-scale convection known as salt fingers. Although scientists have known about…
Read MoreNew Study Reports Large-scale Salinity Changes in the Oceans
Tropical ocean waters have become dramatically saltier over the past 40 years, while oceans closer to Earth’s poles have become fresher, scientists reported today in the journal Nature. Earth’s warming surface may be intensifying evaporation over oceans in the low latitudes–raising salinity concentrations there–and transporting more fresh water vapor via the atmosphere toward Earth’s poles.
Read MoreWinter in Antarctica Waters: Biology in the Southern Ocean Focus of New International Research Program and Partnerships
As weather warms in New England and we dream of summer days, a team of Woods Hole Oceanographic Institution (WHOI) scientists has headed south to the frigid waters around Antarctica for the first of a series of international cruises to study the distribution and behavior of krill – the major food source for most animals in the Southern Ocean. The eight-member WHOI team is using a variety of new technologies including a remotely operated vehicle to study the small shrimp-like crustaceans that form the base of the food chain for whales, penguins, seals and other marine life.

Significant ramifications including impacting the Atlantic Meridional Overturning Circulation, a key component of global climate, are possible.

Rapid 20th century warming in the Gulf of Maine has reversed long-term cooling that occurred there during the previous 900 years, according to new research that combines an examination of shells from long-lived ocean quahogs and climate model simulations.

The National Science Foundation (NSF) recently awarded $8.3 million to the Woods Hole Oceanographic Institution (WHOI) to extend the life of the Overturning in the Sub-polar North Atlantic Program (OSNAP) in a key part of Earth’s ocean-climate system.
Read MoreStudy reveals Missoula Floods impact on past abrupt climate changes
A new study shows for the first time how massive flood events in the eastern North Pacific Ocean—known as the Missoula Floods—may have in part triggered abrupt climate changes in the Northern Hemisphere during the last deglaciation (approximately 19,000–11,700 years ago).

A research team led by Woods Hole Oceanographic Institution (WHOI) found the fingerprint of a massive flood of fresh water in the western Arctic, thought to be the cause of an ancient cold snap that began around 13,000 years ago.
