Indian ocean acidification and its driving mechanisms over the last four decades from 1980-01-01 to 2019-12-31 (NCEI Accession 0307663)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 05:10 AM | Dataset Last Updated: September 08, 2025 at 12:00 AM
The dataset contains sea-surface temperature, salinity, dissolved inorganic carbon, total alkalinity, pH, and partial pressure of CO2 for the Indian Ocean region (Longitude: 30°E-120°E, Latitude: 30°S-30°N). The data is available from 1980 to 2019 on a monthly time scale. Each of these data variables has a spatial resolution of 1/12°.
