In Brief:

Research shows the Southern Ocean (the continuous body of salt water around Antarctica) absorbs much more carbon from the atmosphere than it releases. The findings confirm this ocean's role as a strong carbon sink and an important shield against some of the effects of human-caused greenhouse gas emissions. 

Article from Science:

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 some of the effects of human-caused greenhouse gas emissions, according to a new NASA-supported study.

Recent research had raised uncertainty about just how much atmospheric carbon dioxide (CO₂) these icy waters absorb. Those studies relied on measurements of ocean acidity – which increases when ocean water absorbs CO₂ – taken by instruments that float in the ocean.
