Decadal variability of the air-sea CO2 fluxes in the Subtropical waters of the Eastern North Atlantic based on empirical algorithms

Abstract

The best procedure for achieving an accurate estimation of seawater CO2 fugacity (fCO2sw) and of the capacity of ocean to absorb CO2 is from of sampling networks. Furthermore robust empirical algorithms make the most of the information that the in situ recordings provide for extending the observed fCO2sw relationships both in temporal and spatial scale. The purpose of this paper is to construct an empirical algorithm for estimating the long-term trend of the fCO2sw and FCO2 over the subtropical waters of the Eastern North Atlantic Ocean.
