Temperature and salinity profiles from CTD casts from the SE Pacific (limit-140 W) from the COLUMBUS ISELIN and other platforms as part of the International Decade of Ocean Exploration / Coastal Upwelling Ecosystems Analysis (IDOE/CUEA) from 17 March 1977 to 30 March 1977 (NODC Accession 7900205)

Temperature and salinity profiles were collected from CTD casts in the SE Pacific (limit 140 W) from the COLUMBUS ISELIN and other platforms from 17 March 1977 to 30 March 1977. Data were collected by the University of Delaware (UD) as part of International Decade of Ocean Exploration / Coastal Upwelling Ecosystems Analysis (IDOE/CUEA) from 08 July 1977 to 29 July 1977. Data were processed by NODC to the NODC standard F022 High-Resolution CTD/STD Output Format. Full format
description is available from the NODC homepage at www.nodc.noaa.gov/General/NODC-Archive/f022.html.

The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.
