    • 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 Guam and the Commonwealth of the Northern Mariana Islands, from 2022-04-12 to 2022-08-10 (NCEI Accession 0289902)

    Metadata Updated: September 2, 2025

    This dataset contains the National Coral Reef Monitoring Program carbonate chemistry data from Guam and the Commonwealth of the Northern Mariana Islands from 2022-04-12 to 2022-08-10. 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.
