Dissolved inorganic carbon, total alkalinity, temperature, and salinity collected from surface discrete observations using coulometer, alkalinity titrator and other instruments from the coral reef MPCO2 buoys at Ala Wai, CRIMP-2, Kaneohe, and Kilo Nalu from 2016-01-08 to 2019-12-20 (NCEI Accession 0176671)

This archival package contains bottle data for dissolved inorganic carbon (DIC) and total alkalinity (TA) for the period January 2016 through December 2019. The bottle samples were collected approximately every two weeks, weather permitting, from approximately 20 cm below the sea surface at the four buoys comprising our network. Commonly challenging weather and sea state conditions at the Kaneohe buoy have rendered the collection of bottle-validation samples more difficult, hence fewer data are available for this station. Collection of samples at the CRIMP-2, Ala Wai, and Kilo Nalu buoys, however, has been more readily achievable and proportionally more data are available for these buoys.
