STD data collected for the EASTROPAC project by the U.S. Fish and Wildlife Service from 1967-08-16 to 1976-02-25 (NCEI Accession 7001333)

This dataset includes STD (salinity, temperature, depth) data collected for the EASTROPAC project in the Pacific Ocean and the North Atlantic Ocean by the U.S. Fish and Wildlife Service from 1967-08-16 to 1976-02-25. See Special Scientific Report - Fisheries No. 588, "Processing of digital data logger STD tapes at the Scripps Institution of Oceanography and the Bureau of Commercial Fisheries, La Jolla, California", by James H. Jones. Data has been processed to the NODC standard High-Resolution STD/CTD Data (F022) format.

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.
