Nutrients other data from CTD, bottle, and XBT casts in the Southern Ocean from 1999-01-01 to 1999-12-31 (NCEI Accession 0000402)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 01:11 AM | Dataset Last Updated: March 16, 2013 at 12:00 AM
Nutrients, salinity, temperature, and other data were collected from multiple ships from January 1, 1999 to December 31, 1999. Data were submitted by Messina Institute of Experimental Thalassography. Data were collected using bottle, CTD, and XBT casts in the Southern Ocean. These data files are in NODC SD2 format. The SD2 file format is used for physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5%), were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information, position, date and time are reported for each station. Each station contains the measurements taken at observed depth levels, but also includes data values interpolated to a set of standard depth levels.
