The equilibrium between the different parameters of the marine carbonate system —dissolved inorganic carbon (DIC), total alkalinity (TA), partial pressure of CO2 (pCO2), and pH —is the core of ocean acidification studies, evaluation of inorganic carbon inventory, and air-sea CO2 fluxes. In this dataset, we collected surface data of DIC, TA, pCO2, pH, temperature, salinity, phosphate, and dissolved silicates from the west fjords of the Svalbard archipelago.
