Variability and stability of anthropogenic CO 2 in Antarctic Bottom Waters observed in the Indian sector of the Southern
International audience We investigated the evolution of anthropogenic CO2 (Cant) in the Antarctic Bottom Water in the Southern Indian Ocean since 1978 based on observations from 16 reocupations. We found that the Cant and the dissolved inorganic carbon increased at about the same rate over the 40-ye...
