Report reveals ‘unseen’ human benefits from ocean twilight zone
A new report from researchers at Woods Hole Oceanographic Institution (WHOI) reveals for the first time the unseen—and somewhat surprising—benefits that people receive from the ocean’s twilight zone. Also known as the “mesopelagic,” this is the ocean layer just beyond the sunlit surface.
Read MoreHow microbes reflect the health of coral reefs
A collaborative study compared seawater from 25 reefs in Cuba and the U.S. Florida Keys varying in human impact and protection, and found that those with higher microbial diversity and lower concentrations of nutrients and organic carbon—primarily caused by human activities—were markedly healthier.

Researchers at WHOI successfully conceived and tested a portable device, DISCO, that performed the first in situ measurements of a highly reactive type of oxygen, known as superoxide, which may…
Read MoreWhales may owe their efficient digestion to millions of tiny microbes
A study by NSF-funded researchers at WHOI shows that the microbial communities inside whales may play an important role in the digestion of one of the ocean’s most abundant carbon-rich lipids: wax esters.
Read MoreWHOI-engineered DISCO allows scientists to measure highly reactive superoxide on coral reefs
WHOI researchers successfully conceived and tested a portable device, DISCO, that performed the first in situ measurements of a highly reactive type of oxygen, known as superoxide, which may play an integral role in the health of coral reefs.
Read MoreThe oceans are losing oxygen, and faster than we thought
WHOI scientists weigh in on a new ICUN report highlighting a 2% decline in marine oxygen levels between 1960 and 2010. The loss of oxygen has triggered an expansion of marine dead zones throughout the global ocean that has put marine life and ecosystems in peril.
Read MoreThe Ocean Twilight Zone’s crucial carbon pump
When CO₂ enters the ocean, where does this heat-trapping gas go? WHOI geochemist investigates how much carbon from the surface ocean is dispatched to the ocean twilight zone–the midlayer of the ocean–and on to the deep ocean.
Read MoreProtecting living corals could help defend the Great Barrier Reef from ocean acidification for decades
Reefs with higher numbers of living corals will be more resilient than expected to damage from acidifying seawater, scientists reported recently in Nature Evolution and Ecology.
Read MoreOcean acidification gets a watchful eye in New England aquaculture ‘hot spot’
Shellfish aquaculture is thriving in New England, but future growth in the industry could be stunted as coastal waters in the region become more acidic. Researchers at WHOI have developed a way to link nutrient load reductions to improvements in the health of Buzzards Bay, Massachusetts, which may an important step toward cleaner and less acidic harbors in the Baystate.
Read MoreThese corals could survive climate change — and help save the world’s reefs
Ocean warming threatens to wipe out corals, but scientists are trying to protect naturally resilient reefs and are nursing some others back to health.
Read MoreThousands of barrels of oil are contaminating Brazil’s pristine coastline. Authorities don’t know where it’s coming from.
WHOI researcher Christopher Reddy has been trying to crack the mystery. Some Brazilian colleagues recently contacted him to help determine the source of the oil, and he’s now analyzing 14…

Polystyrene, a common ocean pollutant, decomposes in sunlight much faster than thought, a new study finds.
Read MoreRiver Detective: WHOI scientist studies river chemistry around the world
Bernhard Peucker-Ehrenbrink has been studying rivers around the world as part of the Global Rivers Observatory network to observe how natural and human-caused environmental changes affect the composition of river water over time.
Read MoreFifty years later, the West Falmouth oil spill yields lasting contributions to remediation efforts
After 175,000 gallons of oil spilled from a barge that ran aground along West Falmouth Harbor, the contaminant has all but disappeared, save a small marsh inlet that continues to serve as a living laboratory for scientists at Woods Hole Oceanographic Institution.

WHOI chemist and marine radioactivity expert shares his thoughts about radioactivity waste leaking from Runit Dome—a bomb crater filled with radioactive soil in the Marshall Islands that is now being penetrated by rising sea levels
Read MoreThis new nanotech could help clean up Earth’s microplastics
“Trying to understand the big picture on plastic and be able to weave a story together is going to take decades,” said Christopher Reddy, an environmental chemist at Woods Hole Oceanographic Institution, who was not involved in the study.
Read MoreNew Study Finds Distinct Microbes Living Next to Corals
WHOI scientists distinct discover microbes living just a few centimeters from the surface of corals near the southern coast of Cuba. The discovery may yield clues about the ecological functions of microbes, and how they find and infect coral colonies.

Two years ago an international team of scientists visited Costa Rica’s subduction zone, where the ocean floor sinks beneath the continent and volcanoes tower above the surface. They wanted to…
