Antarctic Bottom Water (AABW) is known as a long-term sink for anthropogenic CO 2 ( C ant ), but the sink is hardly quantified because of the scarcity of observations, specifically at an interannual scale. We present in this paper an original dataset combining 40 years of carbonate system observatio...
