Antarctic Ocean’s carbon dioxide absorption increased

Antartic Ocean

As per a new study Antarctic Ocean has been absorbing increasing levels of Carbon Dioxide (CO2) , a potent greenhouse gas (GHG) over the past decade. The research study was published in journal Science and was undertaken by an international research team led by Nicolas Gruber, a professor at ETH Zurich. Key facts The study dispels fears that Antarctic Ocean’s (also known as the Southern Ocean) carbon sink might have begun to saturate due to increase in CO2 absorbing levels.

Researchers have found that since the beginning of the millennium, Antarctic Ocean’s carbon sink has become much stronger, regaining its expected strength. Antarctic Ocean seasonally absorbs vast amounts of CO2 from the atmosphere and releases it back later in the year. The seas surrounding Antarctica on an annual average absorb significantly more CO2 than they release.

These seas help to remove a large part of CO2 that human activities emit into the atmosphere. Thereby, slowing down the growth of this GHG in the atmosphere, lessening the rate of climate change. Antarctic Ocean accounts for 40 per cent of the global oceanic uptake of that man-made carbon dioxide.
