Dissolved inorganic carbon, total alkalinity, pH and other variables collected from surface discrete measurements using Coulometer, alkalinity titrator and other instruments from the Philippines from 2012-03-12 to 2015-06-03 (NCEI Accession 0242691)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: July 28, 2026 at 08:31 PM | Dataset Last Updated: November 11, 2021 at 12:00 AM

This dataset contains carbonate chemistry data from samples collected across the Philippines as part of the USAID-funded US Coral Triangle Initiative from 2012-03-12 to 2015-06-03. The project monitors changes to coral reef carbonate chemistry over time at coral reef sites within the Philippines by 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 Philippines region.
