Diving Robots Find that Antarctic Seas Release Surprising Amounts of Carbon Dioxide in Winter

Monday, Aug 20, 2018

The Southern Ocean surrounding Antarctica is regarded by scientists as a large and crucial absorber of carbon dioxide from the atmosphere. New findings from autonomous floats deployed in the Southern Ocean, however, provide the first comprehensive data to suggest that, in winter, the open water nearest the sea ice surrounding Antarctica releases significantly more carbon dioxide into the atmosphere than previously thought.

The study was published Aug. 14 in the journal Geophysical Research Letters by researchers from the Princeton University-based Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project.  First author Alison Gray (University of Washington) conducted the research as a postdoctoral researcher in the Sarmiento Group.  AOS Postdoc Seth Bushinsky, former AOS Associate Research Scholar Joellen Russell (University of Arizona), and AOS Faculty Member Jorge Sarmiento, director of SOCCOM, are among the paper's coauthors.
