Temperature and salinity profiles from CTD casts from R/V ALPHA HELIX from the NE Pacific (limit-180) from 1991-02-09 to 1991-02-25 (NCEI Accession 9200147)

CTD data was collected from the R/V ALPHA HELIX from the NE Pacific (limit-180). Data were collected by the University of Alaska - Fairbanks; Institute of Marine Science (UAK/IMS) from 09 February 1991 to 25 February 1991. Parameters include temperature and salinity profiles. These data are in 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.
