By analyzing more than one million surface ocean observations from the Drake Passage, the researchers detected subtle differences between the CO2 trends in the surface ocean and the atmosphere that suggest a strengthening of the carbon sink that is most pronounced during winter. Although the researchers aren't sure of the exact mechanism driving these changes, it's likely related to winter mixing with deep waters that have not had contact with the atmosphere for several hundred years. These results contrast with previous findings that showed that the Southern Ocean's CO2 sink had been stagnant or weakening from the early 1990s to the early 2000s. "Given the importance of the Southern Ocean to the global oceans' role in absorbing atmospheric CO2, these studies suggest that we must continue to expand our measurements in this part of the world despite the challenging environment," says Colm Sweeney, lead investigator on the Drake Passage study.
