Temperature, salinity, oxygen and other parameter profile data collected by CTD from R/V COLUMBUS ISELIN in the Northwest Atlantic Ocean from 1990-02-10 to 1990-03-29 (NCEI Accession 9100130)

Data was collected by the R/V COLUMBUS ISELIN in NW Atlantic (limit-40 W) during the Amazon Shelf Sediment Study (AMASSEDS) from February to March 1990. The data parameters are: Pressure, Temperature, Salinity, Oxygen, Fluorescence and Sediment Concentration. The entire dataset was submitted on a floppy disk by Dr. Richard Woods Limeburner, Hole Oceanographic Institute, Woods Hole, MA. Data also has been processed and is available in F022-CTD-Hi-Res file format of NODC.

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.
