Cloud amount/frequency, NITRATE and other data from NOAA Ship MILLER FREEMAN in the NE Pacific from 1991-04-02 to 1991-10-05 (NCEI Accession 9200030)

The Conductivity, Temperature and Depth (CTD) and other data were collected in NE Pacific (limit-180) as part of Fisheries-Oceanography Cooperative Investigations (FOCI) project. Data was collected from NOAA Ship MILLER FREEMAN. The data was collected over a period spanning from April 2, 1991 and October 5, 1991. Tape containing 287 castes of CTD was submitted by Ms. Leslie Lawrence of Pacific Marine Environmental Laboratory (PMEL), Seattle, WA.

This data set contains high-resolution data collected using CTD (conductivity-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 1 m. 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. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC.
