Total Carbon Dioxide, Hydrographic, and Nitrate Measurements in the Southwest Pacific During Austral Autumn, 1990: Results from NOAA/PMEL CGC-90 Cruise (1995)
This document presents the procedures and methods used to obtain total carbon dioxide (TCO2), hydrographic, and nitrate data during the NOAA/PMEL research vessel (R/V) Malcolm Baldrige CGC-90 Cruise. Data were collected along two legs; sampling for Leg 1 began along 170° W from 15° S to 60° S, then angled northwest toward New Zealand across the Western Boundary Current. Leg 2 included a reoccupation of some stations between 30° S and 15° S on 170° W and measurements from 15° S to 5° N along 170° W. Along the cruise track 68 CTD stations were occupied for collection of chemical and hydrographic data. The following data report summarizes the TCO2, salinity, temperature, and nitrate measurements from 63 stations. In addition, potential density and potential temperature were calculated from the measured variables.
