Southern Ocean absorbs more CO2 than previously estimated: study

A study by the University of East Anglia (UEA) and Plymouth Marine Laboratory (PML) shows the Southern Ocean absorbs 25% more CO2 than previously thought. Using direct measurements with the eddy covariance technique during seven research cruises, the study found that this ocean region is a substantial CO2 sink. The findings, published in Science Advances, highlight that existing models and float data underestimated CO2 uptake due to temperature variations and low resolution. Researchers emphasise the need for continued high-quality observations and improved models to accurately assess the Southern Ocean's role in climate regulation. (Space Daily)
