Carbon Cycle


A rapidly changing Arctic

Healy, Polarstern

A new study by researchers at Woods Hole Oceanographic Institution (WHOI) and their international colleagues found that freshwater runoff from rivers and continental shelf sediments are bringing significant quantities of carbon and trace elements into parts of the Arctic Ocean via the Transpolar Drift—a major surface current that moves water from Siberia across the North Pole to the North Atlantic Ocean.

The ocean’s ‘biological pump’ captures more carbon than expected

Buesseler sediment trap

Scientists have long known that the ocean plays an essential role in capturing carbon from the atmosphere, but a new study from Woods Hole Oceanographic Institution (WHOI) shows that the efficiency of the ocean’s “biological carbon pump” has been drastically underestimated, with implications for future climate assessments.

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.

Value Beyond View: The Ocean Twilight Zone

How does the ocean twilight zone benefit life on Earth? The ocean twilight zone helps regulates our climate. Storing two to six billion tons of carbon annually. That’s up to six times the amount of carbon emitted from autos worldwide. Preventing an increase in temperature between 6-11°F. The ocean twilight zone supports a healthy ocean ecosystem. Containing 10 times more fish than the rest of the ocean. Providing food for many other animals in the ocean. The ocean twilight zone could also play an important role in feeding a growing population. We are working to better understand this realm in order to inform sustainable management decisions.

Chasing Ocean ‘Snowflakes’

Chasing Ocean ‘Snowflakes’

Scientists envision putting a flotilla of devices in the ocean to act as “eyes” that can track the “marine snow” that drifts down into the ocean.

Marshes, Mosquitoes, and Sea Level Rise

Marshes, Mosquitoes, and Sea Level Rise

In the 1930s, the Cape Cod Mosquito Control Project dug approximately 1,500 miles of ditches across marshes on the Cape to drain their water and reduce the number of ponds where mosquitoes can breed. Woods Hole Oceanographic Institution biogeochemist Amanda Spivak is studying how this and other management decisions have changed the ability of coastal marshes to store carbon and protect against sea level rise.

Mission to the Ocean Twilight Zone

Mission to the Ocean Twilight Zone

The twilight zone is a part of the ocean 660 to 3,300 feet below the surface, where little sunlight can reach. It is deep and dark and cold, and the pressures there are enormous. Despite these challenging conditions, the twilight zone teems with life that helps support the ocean’s food web and is intertwined with Earth’s climate. Some countries are gearing up to exploit twilight zone fisheries, with unknown impacts for marine ecosystems and global climate. Scientists and engineers at Woods Hole Oceanographic Institution are poised to explore and investigate this hidden frontier.
