  abstract:
    en: This dataset consists of the co-located surface discrete fCO2 at 20 ˚C and
      underway fCO2 measurements at sea surface temperature (SST) for 21 cruises spanning
      the Pacific, Atlantic, Indian Oceans and Gulf of Mexico from 1991-07-12 to 2020-04-15.
      In addition, calculated fCO2 from alkalinity (TA) and total dissolved inorganic
      carbon (DIC) are provided. The co-located discrete fCO2 at 20 ˚C and underway
      fCO2 measurements at SST are used to infer the temperature dependence of CO2.
      For the 21 cruises spanning the major ocean basins from 1992-2020 a temperature
      dependence of 4.13 ± 0.01 % ˚C-1 is determined in close agreement with a widely
      used previous empirical estimate of 4.23 ± 0.02 % ˚C-1 for North Atlantic surface
      water. No statistically significant dependence on temperature or inorganic carbon
      speciation of the surface water was discerned as dependency on these factors
      is weak and it was masked by a range of overlapping temperatures and chemical
      compositions. The temperature dependency of calculated fCO2 yield a dependency
      of 4.10 % ˚C-1 for 17 cruises where there are co-located measurements of fCO2,
      alkalinity (TA) and dissolved inorganic carbon (DIC).
