British scientists from the University of East Anglia and the Plymouth Marine Laboratory have demonstrated that the Southern Ocean surrounding Antarctica acts as a powerful sink of carbon dioxide (CO).2) from the atmosphere. The study was published in the scientific journal magazine Science Advances (SciAdv).
Using direct measurements of CO change2 Experts found that between the air and the sea, the ocean around Antarctica removes 25% more CO2.2more than previous calculations suggested.
The data were collected during a scientific trip lasting approximately 175 days in 2019 and 2020. The study was then suspended for a long time due to the Covid-19 pandemic.
The results showed that the Southern Ocean pulls large amounts of carbon from the air during the summer months, which the authors say was underestimated by previous estimates of carbon dioxide uptake due to temperature fluctuations and other changes in the upper water layer.
The researchers noted that to more accurately analyze the absorption capacity of the Southern Ocean, data should be collected during the winter months, but this is difficult to achieve due to difficulties in accessing the polar region.
