Oceanographic profile pCO2 and other measurements collected from the RYOFU MARU, HAKUHO-MARU and other platforms in the Atlantic Ocean, Pacific Ocean, and Indian Ocean from 1981 to 1989 (NCEI Accession 0000440)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 01:12 AM | Dataset Last Updated: July 08, 2025 at 12:00 AM
This dataset contains pCO2 data measured during the period from 1981 to 1989. Each pCO2 data file is tab-separated text file which contains No., year, date, time (UTC) of measurements, position of measurements (latitude, N/S, longitude, E/W), atmospheric pressure (hPa), sea surface temperature(SST), SST flag, xCO2 (CO2 mole fraction in dry air, xCO2(a)) in the ambient air, xCO2(a) flag, xCO2 in the dry air equilibrated with surface seawater (xCO2(s)), xCO2(s) flag, and pH2O.
