PACKAGE DESCRIPTION: This dataset includes discrete sample and profile data collected from POLARSTERN in the South Atlantic Ocean and Southern Oceans (> 60 degrees South) from 2008-02-10 to 2008-04-16. These data include CHLOROFLUOROCARBON-11 (CFC-11), CHLOROFLUOROCARBON-12 (CFC-12), DELTA HELIUM-3, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED OXYGEN, HELIUM, HYDROSTATIC PRESSURE, NEON, NITRATE, NITRITE, Potential temperature (theta), SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE, phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, Coulometer for DIC measurement and bottle. These data were collected by Eberhard Fahrbach of Alfred Wegener Institute for Polar and Marine Research and Steven van Heuven and Hein de Baar of Royal Netherlands Institute for Sea Research as part of the CLIVAR_A12_ANTXXIV_3 data set. CDIAC associated the following cruise ID(s) with this data set: ANT-XXIV/3 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.
