Cloud amount/frequency, NITRATE and other data from ALPHA HELIX in the Gulf of Alaska from 1988-09-14 to 1988-09-29 (NODC Accession 8800279)

The University of Alaska, Institute of Marine Science is responsible for this data collected aboard the R/V Alpha Helix on cruise number HX118 between September 14, 1988 to September 29, 1988 by Dr. T.C. Royer of the Institute of Marine Science. There was a total of 77 stations in the Gulf of Alaska. The station numbers are: 1-77. Field correction for this cruise was taken from Alpha Helix cruise HX118. Field correction for the STD data was derived by comparing single bottle samples to recorded values from the STD sensors. The field correction is based on 9 samples from a total of 11 stations. The CTD data is stored in F022 format in the current NODC storage system.
