Scientists unlock ocean CO2 secrets key to climate: study

SINGAPORE (Reuters) - From giant whirlpools to currents 1,000 km wide, scientists said on Monday they have uncovered how vast amounts of carbon are locked away in the depths of the Southern Ocean, boosting researchers ability to detect the impact of climate change.

Oceans curb the pace of climate change by absorbing carbon dioxide emissions from burning fossil fuels. The Southern Ocean is the largest of these ocean carbon sinks, soaking up about 40 percent of mankind's CO2 absorbed by the seas.

But until now, researchers were unsure what mechanisms were involved because of the remoteness and sheer size of the Southern Ocean.

"By identifying the mechanisms responsible for taking carbon out of the surface layer in the ocean, we're in a much better situation to talk about how climate change might impact that process," said oceanographer Richard Matear, one of the authors of the Southern Ocean study published in the journal Nature Geoscience.
