During the late winter and early spring of 1963 personnel of the U. S. Coast Guard Oceanographic Unit and of the U. S. Naval Oceanographic Office shared two cruises aboard a Coast Guard Ocean Station Vessel in the North Atlantic Ocean. Of 140 serial stations occupied, 45 were taken and processed to completion by Coast Guard personnel. Station planning was cooperative, and all data obtained from the "Coast Guard stations" was provided to the NAVOCEANO party.nSalinities were determined by the Coast Guard using a shipboard inductive salinometer, and by HAVOCEANO from bottled samples returned to their shore laboratory. Both sets of reduced data were monitored by the National Ocean-ographic Data Center and from final processing over 600 salinity comparisons were available. The comparisons were subjected to statistical analysis yielding frequency distri¬bution of differences, standard deviation and several probability limits.
