With the help of strong ocean currents, mountains on the floor of the Southern Ocean play a key role in bringing dissolved carbon to the surface, where it can be released to the atmosphere, a new study led by University of Colorado Boulder scientists finds. The study led by Riley X. Brady and Nicole Lovenduski is the first to detail how carbon travels within and escapes from the Southern Ocean—and has implications for global climate change.
