Dissolved inorganic carbon, total alkalinity, temperature, salinity and other variables collected from profile and discrete sample observations using CTD, Niskin bottle, and other instruments from R/V HI'IALAKAI and OSCAR ELTON SETTE in the U.S. Pacific Reefs from 2012-03-02 to 2014-05-05 (NCEI Acc

This archival package contains data from samples collected and analyzed for total alkalinity (TA) and dissolved inorganic carbon (DIC). From these constituents, alongside temperature, salinity, and depth data, other constituents of the seawater carbonate system can be calculated, including pH (acidity), pCO2 (partial pressure of carbon dioxide), fCO2 (fugacity of carbon dioxide), aragonite and calcite saturation states (Oa, Oc), and the concentrations of bicarbonate ion.
