The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: |
Comparison of discrete and underway carbon dioxide (CO2) related measurements obtained during 21 cruises spanning the Pacific, Atlantic, Indian Oceans and Gulf of Mexico between 1991 and 2020: inferences on the temperature dependence of the fugacity of CO2 (fCO2) in seawater (NCEI Accession 0247018) |
| Abstract: |
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). |
