Partial pressure (or fugacity) of carbon dioxide, dissolved inorganic carbon, pH, alkalinity, temperature, salinity and other variables collected from discrete sample and profile observations using Alkalinity titrator, CTD and other instruments from NATHANIEL B. PALMER in the South Atlantic Ocean,

NCEI Accession 0109933 includes discrete sample and profile data collected from NATHANIEL B. PALMER in the South Atlantic Ocean, South Pacific Ocean and Southern Oceans (> 60 degrees South) from 2011-02-19 to 2011-04-23 and retrieved during cruise CLIVAR_S04P_2011. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-113 (CFC-113), CHLOROFLUOROCARBON-12 (CFC-12), DELTA CARBON-13, DELTA CARBON-14, DELTA HELIUM-3, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED ORGANIC CARBON, DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NEON, NITRATE, NITRITE, Partial pressure (or fugacity) of carbon dioxide - water, Potential temperature (theta), SALINITY, SEA SURFACE TEMPERATURE, SULFUR HEXAFLUORIDE (SF6), TOTAL ALKALINITY (TA), Total Dissolved Nitrogen (TDN), Tritium (Hydrogen isotope), WATER TEMPERATURE, pH, phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement, bottle and spectrophotometer.

These data were collected by Frank J. Millero and Dennis Hansell of Rosenstiel School of Marine and Atmospheric Science, Richard A. Feely and Christopher Sabine of US DOC; NOAA; OAR; Pacific Marine Environmental Laboratory and Andrew Dickson of University of California - San Diego; Scripps Institution of Oceanography as part of the CLIVAR_S04P_2011 data set.

The International CLIVAR Global Ocean Carbon and Repeat Hydrography Program carries out a systematic and global re-occupation of select WOCE/JGOFS hydrographic sections to quantify changes in storage and transport of heat, fresh water, carbon dioxide (CO2), and related parameters.
