Abstract

Fromthe investigation of the oceanic carbonate system it is possible to quantify the oceans as anthropogenic CO2 sinks.With this objective it is intended to contribute to the elaboration of an analytical methodology for the determination of PCO2 and with its measurement in the South Atlantic ocean, currently, very little documented. To estimate the liquid fluxes of CO2 in the atmosphere-ocean interface, it is necessary to study the factors which regulate the distribution of PCO2 in the marine environment. In this way, we will also determine in the same samples salinity, temperature, pH, nutrients and chlorophyll. (AU)
