Salinity and temperature profiles collected by CTD from a helicopter with the LOUIS S. ST. LAURENT in the Arctic Ocean from 1994-07-28 to 1994-08-27 (NCEI Accession 0000846)

Metadata Updated: February 1, 2026

This dataset includes high-resolution CTD/STD data in the Arctic Ocean from 1994-07-28 to 1994-08-27. This is an Arctic Ocean dataset that contains 73 CTD profiles of pressure, temperature, salinity, and sigma-T taken from a helicopter as part of the AOS-94 expedition aboard the CCGS Louis S. St-Laurent during the period 26 July - 1 September 1994.

The data were converted by the National Snow and Ice Data Center (NSIDC) into the NODC standard High-Resolution CTD/STD (F022) format with assistance from David Muus of UCSD/SIO.

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.
