Marine Carbonate System Parameters of the West Spitsbergen Fjords in Late Summer 2022

The focus of research was to assess the current state of carbonate system parameters and CO2 air-sea flux also. We used the data from expeditions to the Isfjorden and Grønfjorden, West Spitsbergen, in September 2022. We carried out an investigation of surface distribution of total alkalinity, pH, salinity, temperature and meteorological observations of CO2 air concentration and wind speed. The obtained data were applied for carbonate parameters calculation. Our observations identify a minor change of distribution of carbonate system parameters. The results showed that both fjords are characterized by carbon dioxide invasion and sufficiently saturated with aragonite and calcite.
