Each summer, the South Asian monsoon transforms parts of India from semi-arid into lush green lands able to support farming. The annual infusion of rainfall and resulting runoff into the Ganges, Brahmaputra, and other rivers in the region also has a very different, but no less dramatic, impact on the Bay of Bengal in the northeast Indian Ocean.
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.
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.
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.
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.
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.
A study newly published in Nature Geoscience has solved a ten-year-old mystery about the source of an essential nutrient in the ocean.
Hydrocarbonsmolecules critical to lifeare routinely generated by the simple interaction of seawater with the rocks under the Lost City hydrothermal vent field in the Atlantic Ocean. The production of such building blocks of life makes Lost City-like vents strong contenders as places where life might have originated on Earth, according to research led by the University of Washington and the Woods Hole Oceanographic Institution.
A research team led by Dennis McGillicuddy of the Woods Hole Oceanographic Institution has shown that episodic, swirling current systems known as eddies act to pump nutrients up from the deep ocean to fuel such blooms.
