    • Pacific Reef Assessment and Monitoring Program: Dissolved inorganic carbon, total alkalinity, pH and other variables collected from surface discrete measurements using Coulometer, alkalinity titrator and other instruments from the US Pacific Islands from 2006-02-12 to 2012-05-18 (NCEI Accession 0232262)

    Metadata Updated: December 1, 2025

    This dataset contains the Pacific Reef Assessment and Monitoring Program (RAMP) carbonate chemistry data from American Samoa, Pacific Remote Island Areas, Guam and the Commonwealth of the Northern Marianas Islands, and the Hawaiian Archipelago from 2006-02-12 to 2012-05-18. 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. 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 monitoring sites in coral reef areas of the U.S. Pacific region.
