Ocean Sink for Man-made CO2 Measured

Friday, Mar 15, 2019

The ocean is an important sink for anthropogenic CO2 and has absorbed roughly 30% of our emissions between the beginning of the industrial revolution and the mid-1990s.  This effect is an important moderator of climate change.  In a new study published in Science and led by former AOS Postdoc Nicholas Gruber (ETH Zurich), the authors quantify the oceanic sink for anthropogenic carbon dioxide (CO2) over the period 1994 to 2007 by using observations from the global repeat hydrography program and contrasting them to observations from the 1990s.  Brendan Carter (PMEL), a former AOS postdoc, AOS Research Oceanographer Bob Key, and former AOS Postdoc Chris Sabine (University of Hawaii - Manoa) are among the paper's co-authors.
