Integrated Marine Observing System (IMOS) sea surface and atmospheric fCO2 measurements in the Southern Ocean onboard R/V Investigator in 2018 (NCEI Accession 0209040)

browse graphicPreview graphic
This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Investigator in the Indian Ocean, South Pacific Ocean, Southern Oceans from 2018-08-20 to 2019-01-09. 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.
