Carbon Dioxide, Hydrographic, and Chemical Data Obtained During the R/V Nathaniel B. Palmer Cruise in the Southern Ocean on CLIVAR Repeat Hydrography Section S04P (Feb. 19 - Apr. 23, 2011) (NCEI Accession 0109933)

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.
