Popis

Temperature, depth, salinity, and sigma-T data were collected using STD/CTD casts from OCEANUS in the Atlantic Ocean from June 6, 1978 to June 22, 1978. Data were submitted by University of Washington as part of the International Decade of Ocean Exploration / combination of USSR POLYGON project and US MODE (IDOE/POLYMODE) project. Data were processed by NODC to the NODC standard High-Resolution STD/CTD Data (F022) format. Full F022 format descriptions are available at http://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.
