Cloud amount/frequency, NITRATE and other data from ALPHA HELIX in the Coastal Waters of S. Alaska from 1991-07-24 to 1991-11-14 (NODC Accession 9200039)

Metadata Updated: February 27, 2019

The Conductivity, Temperature and Depth (CTD) and other data were collected in Coastal Waters of S. Alaska. Data was collected in five cruises from Ship ALPHA HELIX. The data was collected over a period spanning from July 24, 1991 and November 14, 1991. Data was submitted in a tape from cruises L09-L011 and HX159-160 by Dr. Chirk Chu, Institute of Marine Science, University of Alaska, Fairbanks, AK.

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.
