Glacial meltwater impacts marine carbonate chemistry on Iceland's continental shelf

This dataset presents seawater carbonate chemistry measurements and ancillary hydrographical data collected on the southeast Iceland shelf between June 26th and July 1st 2023 onboard R/V Skagerak, and from freshwater endmembers on shore. The dataset contains information on the measured contents of dissolved inorganic carbon, total alkalinity, and stable isotope composition of dissolved inorganic carbon from water samples, as well as the calculated values of the saturation state of aragonite, partial pressure of carbon dioxide and the air-sea flux of carbon dioxide. The dataset contains four files: iceland_metadata.xlsx: Metadata of all datafiles. Contains column-headers, units and parameter description. iceland_discrete.csv: Discrete and continous measured and calculated marine carbonate system variables. iceland_underway.csv: Hydrographical sensor data from the ships Ferrybox system. iceland_ctd.csv: Hydrographical sensor data from the ships CTD.
