National Coral Reef Monitoring Program: Dissolved inorganic carbon, total alkalinity, pH and other variables collected from surface discrete measurements using Coulometer, alkalinity titrator and other instruments from Oahu, Hawaii, from 2021-05-19 to 2021-07-20 (NCEI Accession 0283239)

This dataset contains the National Coral Reef Monitoring Program carbonate chemistry data collected around Oahu, Main Hawaiian Islands in 2021. 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.

The instruments were each separately calibrated at the beginning of each cell with a minimum of two sets of these gas loop injections.; Standardization frequency: "1) Gas loops were run near the beginning of each cell; 2) CRM’s supplied by Dr. A. Dickson of SIO, were also measured near the beginning; and 3) Duplicate samples were typically run throughout the life of the cell solution."; CRM manufacturer: Andrew Dickson's lab at Scripps Institute of Oceanography; Preservation method: Saturated Mercury Chloride (HgCl2) Solution; Preservative volume: 0.2 ml; Preservative correction: The DIC values were corrected for dilution by 0.2 ml of saturated HgCl2 used for sample preservation.

The numbers provided for these 3 samples (flask 42 to 44) were corrected from the measured value by the average offset which was 0.087. 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. Bottle salinity values are only used if CTD salinity data are not available.; Quality flag convention: WOCE water sample quality flag; Researcher name: Dana Greeley, Julian Herndon, and Christopher Ikeda (contact PI Simone Alin for all inquiries); Researcher institution: Pacific Marine Environmental Laboratory, National Oceanic and Atmospheric Administration; and Cooperative Institute for Climate, Ocean, and Ecosystem Studies, University of Washington.
