Boatswain C. H. Bartlett was the commanding officer of the General 

 Greene. Lieut. R. M. Hojde was detailed as ice observation officer, 

 and remained at sea with one enlisted man as an assistant throughout 

 the entire patrol season in order to aid the commanding officer of the 

 vessel actually on duty in ice-patrol matters, and to keep a continuous 

 and uniform record of the year's work, Mr. Olav Mosby, senior 

 physical oceanographer, was assigned to the General Greene to make 

 scientific observations of an oceanographic nature. 



During the month of March, 1932, the General Greene made three 

 observation cruises in the ice regions near the Grand Banks to learn 

 the ice conditions. The General Greene was greatly hindered in this 

 work by severe and stormy weather. While on this duty the ice 

 observation vessel based on St. John's, Newfoundland. On March 28 

 25 bergs were reported just east of the Grand Banks between latitudes 

 46° 12' N. and 46° 40' X., and it was thought advisable to begin the 

 regular patrol. Accordmgly the cutter Tampa sailed from Boston 

 April 1, 1932, and inaugurated the international ice patrol for the 

 season 1932. The cutter Pontchartrain relieved the Tampa on April 

 18, 1932. Thereafter the Tampa and Pontchartrain made alternate 

 cruises in the ice regions of about 15 days each, this time being 

 exclusive of the 5 or 6 daj^s occupied in going to and from port. 

 The cutters used Halifax, Nova Scotia, as a base for fuel and supplies 

 during the ice season. 



Four times each day radio broadcasts giving locations or limits of all 

 known ice were broadcast for the benefit of shipping approaching the 

 ice-patrol area. Each broadcast was sent twice so that if anyone 

 failed to receive the information on the first sending they would not 

 have to make a special request for ice information or wait until the 

 next broadcast. The difl'erent bergs, if not later sighted or reported, 

 were kept from four to seven days in the broadcasts before they were 

 dropped. Special messages were sent to any vessel that inquired for 

 special information relative to ice, weather, steamer lanes, and similar 

 matters. Once each day a compilation of all ice sighted or reported 

 during the previous 24 hours was transmitted by radio direct to the 

 United States H3'drographic Office at Washington, D. C. This in- 

 formation was given dissemination to all shipping by the hydrog- 

 rapher of the United States Navy. 



During the season the General Greene made three oceanographic 

 cruises and dj^namic surveys of the patrol area, and from the data 

 collected three current charts were drawn of the ice regions. These 

 charts were turned over to the cutters on patrol as soon as they were 

 completed for use in determining the probable set and drift of bergs. 

 The actual observed drifts followed closely the computed currents. 



As in previous years, isotherm charts were drawn from the surface 

 sea water temperatures collected from vessels crossing the ice regions.
