Surface underway measurements of partial pressure of carbon dioxide (pCO2) in water and atmosphere, sea surface salinity, temperature and other parameters obtained during the R/V Discovery UK-NERC Porcupine Abyssal Plane (PAP) cruise (EXPOCODE 74EQ20171115) in the South Atlantic Ocean from 2017-11-15 to 2017-12-17 (NCEI Accession 0184840)
PACKAGE DESCRIPTION: This dataset includes surface underway, chemical, meteorological and physical data collected from R/V Discovery UK-NERC Porcupine Abyssal Plane (PAP) cruise (EXPOCODE 74EQ20171115) in the South Atlantic Ocean from 2017-11-15 to 2017-12-17. 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.
