How Southern Ocean Intermediate Waters Regulate Global CO2 Levels
asiaresearchnews.comNew research from National Taiwan University reveals that Antarctic Intermediate Water, located 500 to 1,500 meters deep, is a primary regulator of atmospheric carbon dioxide. The study shows that colder, fresher intermediate waters historically sequestered more carbon, while warmer, saltier conditions allowed CO2 to escape back into the atmosphere. The findings highlight a critical link between Antarctic iceberg melt and the ocean's ability to store carbon. As ice loss accelerates, the reduction in freshwater input may weaken the ocean's capacity to lock away emissions, potentially accelerating global warming.
