abstract: This dataset includes biological, chemical, discrete sample, optical, physical and profile data collected from POLARSTERN in the South Atlantic Ocean and Southern Oceans (> 60 degrees South) from 2014-12-02 to 2015-02-01. These data include CHLOROPHYLL, CHLOROPHYLL A, DISSOLVED INORGANIC CARBON (DIC), DISSOLVED ORGANIC MATTER, DISSOLVED OXYGEN, FLUORESCENCE, HYDROSTATIC PRESSURE, NITRATE, NITRITE, PARTICULATE ORGANIC CARBON, PARTICULATE ORGANIC NITROGEN (PON), PHAEOPHYTIN, PIGMENTS, Potential temperature (theta), SALINITY, TOTAL ALKALINITY (TA), WATER TEMPERATURE, diatom, pH, phosphate and silicate. The instruments used to collect these data include Alkalinity titrator, CTD, bottle and spectrophotometer. These data were collected by Olaf Boebel of Alfred Wegener Institute for Polar and Marine Research, Melchor Gonzalez-Davila and Magdalena Santana-Casiano of Universidad de Las Palmas de Gran Canaria and Andrew Dickson of University of California - San Diego; Scripps Institution of Oceanography as part of the SOCCOM_06AQ20141202 data set. CDIAC associated the following cruise ID(s) with this data set: ANT-XXX_2 and PS89
purpose: This dataset is available to the public for a wide variety of uses including scientific research and analysis.
