Arctic carbon conveyor belt discovered

Every year, the cross-shelf transport of carbon-rich particles from the Barents and Kara Seas could bind up to 3.6 million metric tons of CO2 in the Arctic deep sea for millennia. In this region alone, a previously unknown ...

Experts explain slowing ocean currents

For decades, oceanographers have been measuring the Atlantic Meridional Overturning Circulation (AMOC), a large system of ocean currents that greatly influence Earth's climate. In recent years, the data show it is weakening. ...

Marine bacteria take in carbon dioxide through photosynthesis

Knowing whether or not marine microbes engage in photosynthesis—the use of sunlight to turn carbon dioxide and water into energy—could help scientists to learn if ocean bacteria play a role in the global carbon cycle.
