Data_Sheet_1_Effects of Ocean Acidification on Calcification of the Sub-Antarctic Pteropod Limacina retroversa.PDF

Ocean acidification is expected to impact the high latitude oceans first, as CO 2 dissolves more easily in colder waters. At the current rate of anthropogenic CO 2 emissions, the sub-Antarctic Zone will start to experience undersaturated conditions with respect to aragonite within the next few decad...
