WHOI scientists aim to improve the study of marine heatwaves

Researchers call for regional and context-specific approaches to these extreme events


Coastal retreat in Alaska is accelerating because of compound climate impacts

Observations have shown coastal erosion as an increasing Arctic hazard, but other hazards—including sea level rise and permafrost thaw subsidence—have received less attention.


Coring a Salt Marsh

A new report on coastal resilience

New report released during NY Climate Week and upcoming UN General Assembly high-level plenary meeting on threats posed by sea level rise


Can adding iron to the ocean help it absorb CO2?

A newly published article spells out the work needed to assess the potential of ocean iron fertilization as a low cost, scalable, and rapidly deployable method of mCDR.

Sea Surface Temperature Research Provides Clear Evidence of Human-Caused Climate Change

New oceanic research provides clear evidence of a human “fingerprint” on climate change and shows that specific signals from human activities have altered the seasonal cycle amplitude of sea surface temperatures.

How Long Can the Ocean Slow Global Warming?

How Long Can the Ocean Slow Global Warming?

It is 4:30 a.m., far from land. A group of scientists clad in bright yellow foul-weather gear gathers in the open bay of a research ship. They wait in the chill air while the ship’s crew brings their instrument back on board after a 6-mile roundtrip to the ocean floor. As the sun begins to rise, the scientists carefully remove seawater collected at various depths from the 36 bottles on the rosette-shaped sampler. Meanwhile, the…


Ocean Circulation and a Clam Far From Home

Ocean Circulation and a Clam Far From Home

In my first year of graduate school, I was stumped by a big question on my final exam in biological oceanography. Maybe I had missed the relevant lecture or an assigned reading, but I could not answer the question: How can the same species of clams, snails, and other marine invertebrates be found along the coastlines of both the eastern United States and Portugal? After the exam, I found the answer in a classic research…


The Once and Future Circulation of the Ocean

The Once and Future Circulation of the Ocean

The short history of modern oceanographic observations—less than a century’s worth, really—doesn’t give us a long track record to evaluate how the ocean’s circulation has operated and changed in the past. Nor does it give us enough data to assess how changes in the ocean shifted Earth’s climate in the past, or how they could cause climate changes in the future. To examine the ocean’s role in climate change, scientists use computer models that simulate…


What Other Tales Can Coral Skeletons Tell?

What Other Tales Can Coral Skeletons Tell?

In 2003, we traveled by ship to the New England Seamounts—a chain of extinct, undersea volcanoes about 500 miles off the East Coast of North America—to help collect dead corals that have been on the bottom of the ocean for thousands of years. For scientists, these corals are like deep-sea time machines. As they grew, the skeletons of these long-living corals incorporated trace chemicals from surrounding seawater. By analyzing chemical variations in the corals’ annual…


The Coral-Climate Connection

The Coral-Climate Connection

Are the climate changes we perceive today just part of the Earth system’s natural variability, or are they new phenomena brought about by human activities? One way to find out is to look back at the past to get a long-term picture of how Earth’s climate has fluctuated. But it is a major challenge to find records of past climate with sufficiently high resolution to capture evidence of abrupt and brief climate shifts. Scientists have…

Study offers first definitive proof that Gulf Stream has weakened

“New research from the Woods Hole Oceanographic Institution offers the first conclusive evidence that the Gulf Stream has weakened. The powerful ocean current off the East Coast influences regional weather, climate and fisheries, and the finding could have significant implications both for New England and the global climate.”


What Happens to Marine Life When There Isn’t Enough Oxygen?

In September of 2017, Woods Hole Oceanographic Institution postdoctoral scholar Maggie Johnson was conducting an experiment with a colleague in Bocas del Toro off the…


Maine’s having a lobster boom. A bust may be coming.

The waters off Maine’s coast are warming, and no one knows what that’s going to mean for the state’s half-billion-dollar-a-year lobster industry—the largest single-species fishery in North America. Some fear that continued warming could cause the lobster population to collapse. To understand what’s happening to the ecosystem of the Gulf of Maine, says Glen Gawarkiewicz, an oceanographer at Woods Hole Oceanographic Institution, in Massachusetts, you have to look beyond it—see how it’s affected by the atmosphere, ocean currents, and rivers that flow into it.
