PACKAGE DESCRIPTION: This dataset includes Surface underway, chemical, meteorological and physical data collected from NOAA Ship RONALD H. BROWN in the South Atlantic Ocean from 2013-12-23 to 2014-02-04 and retrieved during cruise 33RO20131223. These data include AIR-SEA DIFFERENCE - PARTIAL PRESSURE (OR FUGACITY) OF CARBON DIOXIDE, BAROMETRIC PRESSURE, Partial pressure (or fugacity) of carbon dioxide - atmosphere, Partial pressure (or fugacity) of carbon dioxide - water, SALINITY and SEA SURFACE TEMPERATURE. The instruments used to collect these data include Carbon dioxide (CO2) gas analyzer, Shower head chamber equilibrator for autonomous carbon dioxide (CO2) measurement, not applicable and thermosalinographs. These data were collected by Rik Wanninkhof of NOAA Atlantic Oceanographic and Meteorological Laboratory as part of the VOS_A16S_2013 data set.
