Optimal evaluation of the surface ocean CO 2 system in the northern North Atlantic using data from voluntary observing ships
This work evaluates whether an accurate calculation of the entire CO 2 system in the northern North Atlantic can be carried out using a combination of in situ fugacity of CO 2 (fCO 2 ) and ancillary data often measured on Voluntary Observing Ships (VOS), i.e., sea surface temperature (SST) and sea s...
