Reconstructed carbonate system in the Bransfield Strait over the last 30 years (1990-2019)

We reconstructed carbonate system parameters through multivariate linear equations in the Bransfield Strait, northern Antarctic Peninsula. We used hydrographic data (potential temperature, salinity, dissolved oxygen) and measured total alkalinity (TA) and total inorganic carbon (CT) to develop the best-fitted equations to reconstruct TA and CT in those stations where they were not available. With reconstructed TA and CT, the software CO2Sys v2 was used to reconstruct the other carbonate system parameters (partial pressure of carbon dioxide - pCO₂, pH, aragonite and calcite saturation state). In this version, available data are:

- longitude

- latitude

- pressure (db)

- neutral density (kg m^-3)

- potential temperature (°C)

- salinity

- dissolved oxygen (umol kg^-1)

- total alkalinity (umol kg^-1)

- total inorganic carbon (umol kg^-1)

- partial pressure of carbon dioxide (uatm)

- pH

- aragonite and calcite saturation state
