Partial pressure (or fugacity) of carbon dioxide, water temperature, salinity and other variables collected from surface underway observations during the SA Agulhas II cruise in the South Atlantic Ocean, Indian Ocean from 2025-04-18 to 2025-05-13 (NCEI Accession 0315102)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: May 29, 2026 at 08:45 PM | Dataset Last Updated: May 21, 2026 at 12:00 AM
This dataset includes surface underway, chemical, meteorological and physical data collected from SA Agulhas II cruise in the South Atlantic Ocean, Indian Ocean from 2025-04-18 to 2025-05-13. These data include Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water water temperature, salinity and barometric pressure. The Goodhope line between Cape Town, South and SANAE in Antarctica has been continuous sampled every summer (Dec-Feb) since 2008 from the SA Agulhas I (from 2008 to 2011) and SA Agulhas II since 2012. The purpose is to contribute to the global SOCAT quality controlled and gridded dataset is then used for the reconstructions of the CO2 flux in the Southern Ocean. This will continue at least annually in summer, occasional winter and spring lines.
