Integrated Marine Observing System (IMOS) sea surface and atmospheric fCO2 measurements in the South Pacific Ocean, Southern Ocean, Tasman Sea onboard R/V L'Astrolabe in 2025 (NCEI Accession 0311455)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 27, 2026 at 09:43 PM | Dataset Last Updated: July 09, 2026 at 12:00 AM
This dataset includes surface underway, chemical, meteorological and physical data collected from R/V L'Astrolabe in the South Pacific Ocean, Southern Ocean, Tasman Sea in 2025. These data include partial pressure (or fugacity) of carbon dioxide (pCO2) in water and air, sea surface temperature, sea surface salinity, barometric pressure, wind direction and wind speed. The instruments used to collect these data include barometric pressure sensor and carbon dioxide (CO2) gas analyzer.
