An update of anthropogenic CO2 storage rates in the western South Atlantic basin and the role of Antarctic Bottom Water
7 páginas, 4 tablas, 3 figuras, 1 apéndice.-- Proyecto Carbochange The western basin of the South Atlantic from 10°N to 55°S and from the coast to the Mid-Atlantic Ridge is a region with large uncertainties as to the storage of anthropogenic CO2 (Cant). Our analysis of data of the last three decades...
