Surface underway measurements of partial pressure of carbon dioxide (pCO2) in water and atmosphere, sea surface salinity, temperature and other parameters obtained during R/V James Clark Ross cruises in the South Atlantic Ocean from 2017-02-05 to 2017-05-01 (NCEI Accession 0184841)
PACKAGE DESCRIPTION: This dataset includes surface underway, chemical, meteorological and physical data collected during R/V James Clark Ross cruises in the South Atlantic Ocean from 2017-02-05 to 2017-05-01. These data include partial pressure (or fugacity) of carbon dioxide - atmosphere, partial pressure (or fugacity) of carbon dioxide - water, sea surface salinity and sea surface temperature and barometric pressure. The instruments used to collect these data include barometric pressure sensor and carbon dioxide (CO2) gas analyzer.
