The project monitors changes to coral reef carbonate chemistry over time, at U.S.-affiliated Pacific coral reef sites, through quantifying key chemical parameters that are expected to change with ocean acidification. This effort addresses multiple OAP programmatic mission areas by maintaining the coral reef portion of the OA monitoring network and developing a procedure for data synthesis, assimilation, and distribution. Incorporating an interdisciplinary approach, this project collects, processes, analyzes, and stewards dissolved inorganic carbon (DIC) and total alkalinity (TA) water sample data to document seawater carbonate chemistry at Class 0, I, II, and III climate monitoring sites in coral reef areas of the U.S. Pacific region. To provide high-quality carbonate chemistry data for U.S. coral reef areas at several spatial and temporal scales, in close partnership with the larger CRCP NCRMP and OAP/PMEL NOA-ON efforts.

Data are NULL when bottle salinity data were not collected and/or not used.; Uncertainty: The uncertainty could be as much as plus or minus 0.5. As an example, if one were to increase salinity by 0.5, then the CO2sys calculated pH would drop by ~0.006, pCO2 rises up by 6, WAragonite goes down by 0.001.
