Aircraft Reveal a Surprisingly Strong Southern Ocean Carbon Sink

The Southern Ocean is indeed a significant carbon sink — absorbing a large amount of the excess carbon dioxide emitted into the atmosphere by human activities — according to a new study led by the National Center for Atmospheric Research (NCAR).

Southern Ocean confirmed as strong carbon dioxide sink

Research published in recent years has suggested the Southern Ocean might be absorbing less carbon dioxide (CO2) from the atmosphere than previously thought.  But a new study published this week in the journal Science confirms the role of the Southern Ocean as a significant carbon sink.

NASA-supported Study Confirms Importance of Southern Ocean for Absorbing CO2

Observations from research aircraft show that the Southern Ocean absorbs much more carbon from the atmosphere than it releases, confirming it is a very strong carbon sink and an important buffer for the effects of human-caused greenhouse gas emissions, according to a new, NASA-supported study.
