This document presents the procedures and methods used to obtain carbon dioxide (CO2), hydrographic, and chemical data during the R/V Meteor Expedition 11/5 in the South Atlantic Ocean, including the Drake Passage (Section A-12); the Northern Weddell Sea; and the Eastern South Atlantic Ocean (Section A-21). This cruise was conducted as part of the World Ocean Circulation Experiment (WOCE). The cruise started from Ushuaia, Argentina, on January 23, 1990, and ended at Capetown, South Africa on March 8, 1990. Samples were collected at 78 stations that covered the Drake Passage (56-63 degrees S); the Northern Weddell Sea (45-35 degrees W); a section along the 58oW parallel (25 degrees W-prime meridian); and two segmented S-N sections between the Northern Weddell Sea and Capetown, South Africa. Measurements taken at WOCE sections A-12 and A-21 included pressure, temperature, salinity measured by the Conductivity, Temperature and Depth sensor (CTD); bottle salinity; oxygen; phosphate; nitrate; nitrite; silicate; total carbon concentration (TCO2); and partial pressure of CO2 (pCO2) measured at 20 degrees C. In addition, potential density at 0 decibar (dbar) and potential temperature were calculated from the measured variables.
