The Antarctic Ocean has been absorbing increasing levels of carbon dioxide over the past decade, a new study has found, dispelling fears that the ocean's carbon sink might have begun to "saturate".

The Antarctic Ocean, also known as the Southern Ocean, seasonally absorbs vast amounts of carbon dioxide from the atmosphere and releases it back later in the year.

On an annual average the seas surrounding Antarctica absorb significantly more CO2 than they release. These seas remove a large part of the CO2 that human activities emit into the atmosphere, thereby slowing down the growth of this greenhouse gas in the atmosphere, lessening the rate of climate change.

The Southern Ocean accounts for 40 per cent of the global oceanic uptake of that man-made carbon dioxide.

From the year 2005, however, scientists pointed out that the Southern Ocean carbon sink might have begun to "saturate." Based on model results, they suggested that it had not increased since the late 1980s.
