SOUND VELOCITY and Other Data from FIXED PLATFORM and Other Platforms From NE Atlantic (limit-40 W) and Others from 1986-05-12 to 1989-11-12 (NCEI Accession 9000121)

The sound velocity and other data in this accession has been processed by NODC from a tape submitted by the originator containing Inverted Echo Sounder data from the R/V Endeavor cruise 205, October 1989. It also contains data previously sent to NODC for the Seasonal Equatorial Atlantic (SEQUAL) project for sites Sal and Sol. These data are in NODC format for pressure gauge data (F017) and the format described in the documentation. The file Sal represents observations from several deployments (overlap of instruments) therefore there are duplicates in the data. These data have been released by Dr. Eli Katz from Lamont-Doherty Geological Observatory. CTD data was also sent and can be found under track numbers TV5152-TV5154. Data has been re-processed and re-submitted on March 24, 1991. A01402 W18760

Data has been processed by NODC to the NODC standard High-Resolution CTD/STD (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.
