Scientists have found lingering radioactivity in the lagoons of remote Marshall Island atolls in the Pacific Ocean where the United States conducted 66 nuclear weapons tests in the 1940s and 1950s.
A new study from WHOI indicates that superoxide—a natural toxin believed to be the main culprit behind coral bleaching—may actually play a beneficial role in coral health and resilience.
A new study may have cracked the longstanding “marine methane paradox,” finding that the answer may lie in the complex ways that bacteria break down substances excreted into seawater by living organisms.
In novel lab observations of interactions between corals and planktonic bacteria, known as picoplankton, researchers found that corals are selectively feeding on specific types of bacteria—the same bacteria whose growth is promoted by organic matter and nutrients that are released by the corals.
Scientists demonstrate that a key organism in the ocean’s food web will start reproducing at high speed as carbon dioxide levels rise, with no way to stop when nutrients become scarce.
Ancient rocks harbored microbial life deep below the seafloor, reports a team of scientists, confirming a long-standing hypothesis that interactions between mantle rocks and seawater can create potential for life even in hard rocks deep below the ocean floor.
As temperatures rise, some of the carbon dioxide stored in Arctic permafrost meets an unexpected fate—burial at sea. As many as 2.2 million metric tons of carbon dioxide (CO2) per year are swept along by a single river system into Arctic Ocean sediment, according to a new study.
New research proves that the dissolved metals from hydrothermal plumes follow deep-sea currents to provide a major source of iron to the world's oceans.
WHOI assistant scientist Anna Michel was chosen by the National Academy of Sciences to receive a 2015 Gulf Research Program Early-Career Research Fellowship.
As the ocean absorbs atmospheric carbon dioxide (CO2) released by the burning of fossil fuels, its chemistry is changing, lowering its pH in a process known as ocean acidification. This process also removes carbonate ions, an essential ingredient needed by corals and other organisms to build their skeletons and shells.
Scientists from WHOI calculated the first direct estimate of how much and in what form organic carbon is exported to the ocean by rivers.
Good management has brought the $559 million United States sea scallop fishery back from the brink of collapse over the past 20 years. However, its current fishery management plan does not account for longer-term environmental change like ocean warming and acidification that may affect the fishery in the future. A group of researchers from WHOI, NOAA's National Marine Fisheries Service, and Ocean Conservancy hope to change that.
Scientists have discovered a surprising new short-circuit to the biological pump. Sinking particles of stressed and dying phytoplankton release chemicals that can have a jolting, steroid-like effect on marine bacteria feeding on the particles.
Just as crocus and daffodil blossoms signal renewal and the start of a warmer season on land, a similar "greening" event—a massive phytoplankton bloom—unfolds each spring in the Atlantic Ocean from Bermuda to the Arctic. But, what happens to all that organic material produced in the surface ocean?
A new study led by scientists at the Woods Hole Oceanographic Institution (WHOI) points to the deep ocean as a major source of dissolved iron in the central Pacific Ocean.
A new study shows exposing corals to added nutrients increases their erosion and dissolution rate tenfold.
In a study published in the journal Science, a research team led by WHOI demonstrated that they can identify and measure proteins in the ocean, revealing how singled-celled marine organisms and ocean ecosystems are operating.
WHOI scientists report on the first direct calculation of global mercury pollution in the world's ocean. The study shows three times more mercury in upper ocean since the Industrial Revolution.
Ocean researchers working on the coral reefs of Palau in 2011 and 2012 made two unexpected discoveries that could provide insight into corals’ resistance and resilience to ocean acidification and aid in the creation of a plan to protect them.
Scientists have discovered a vast plume of iron and other micronutrients more than 1,000 km wide billowing from hydrothermal vents in the South Atlantic Ocean. The finding, published in the journal Nature Geoscience, calls past estimates of iron abundances into question, and may challenge researchers’ assumptions about iron sources in the world’s seas.
