Oceanographic work of the United States Coast Guard in the western North Atlantic in 1939 and plans for 1940
During the 1939 ice season the United States Coast Guard cutters Chelan and Champlain were assigned as patrol-cutters to conduct the International Service of Ice-Observation and Ice-Patrol. The 125-foot patrol-boat General Greene was again assigned as the oceanographic vessel of the Ice-Patrol Force. The ice-observation officer, who has charge of the scientific work on the patrol-cutters, was Lieutenant W. P. Hawley, and the oceanographer in charge of the scientific work on the oceanographic vessel was Floyd M. Soule.The patrol-cutters made 11 cruises of about two weeks each in the region of the Grand Banks of Newfoundland between March 9 and August 23. From data collected on these cruises, 11 fort-nightly sea-surface isothermal charts were prepared and will be published in United States Coast Guard Bulletin No. 29. The ice-patrol was discontinued on August 23, the latest date in the history of this international service.
