UW Researchers detect carbon dioxide outgassing in the Southern Ocean

Alison Gray (UW Oceanography) and her team recently published a paper in AGU about significant carbon dioxide outgassing in the Southern Ocean during the winter. The Southern Ocean was previously thought to be a carbon sink, based off of measurements that were sparse and tended to be from the summer. This paper used data from SOCCOM (Southern Ocean Carbon and Climate Observations and Modeling) floats that take measurements year-round.

Steve Riser (UW Oceanography) leads the UW team that is a part of SOCCOM. They build and test the floats before they are deployed, and have a key role in SOCCOM’s observational group.
