Colocated multitracer data sets

A data set of observed fCO2 in the Nordic Seas and Barents Sea measured by an autonomous instrument onboard R/V G.O.Sars has been used as basis for a multi tracer data set of biogeochemical and physical variables. Physical variables from models (TOPAZ and NCEP/NCAR) and satellites (SeaWiFS) have been co-located with the observed data based on time and position.

Using the observed fCO2 and published algorithms for alkalinity all other carbon parameters (DIC, pH, HCO3-, CO32-, and calcite and aragonite saturation state) have been calculated.
