the first use of the Lockheed Hercules (SC-130B) aircraft which 

 was used for an ice patrol flight on 24 May and is planned to be used 

 for flying all ice patrol flights starting in 1963. 



A total of 42 ice observation flights totaling 299.7 hours during the 

 season were made from 3 March to 21 June 1962. These flights 

 averaged 1,141 miles in length and 7.1 hours duration. Xme preseason 

 flights totaling 50 hours were made between 27 December and 28 

 February. These preseason ice reconnaissance flights were mainly 

 for the purpose of guarding against any undetected movement of 

 ice into the shipping lanes and to enable determination of the com- 

 mencement of full ice patrol services. Fifteen postseason flights 

 totaling 88.7 hours were made from 28 June to 10 September, 

 also for the purpose of detecting any unusual post season movement of 

 ice into the effective shipping tracks. 



AU seasonal flights were planned by the International Ice Tatro 

 Operations Office, whose duties included the continuous search for and 

 location of all ice in the Grand Banks area, the collection, plotting and 

 evaluation of ah ice information and the dissemination of pertinent 

 ice information to shipping. The main consideration m the flight 

 planning was the primary Ice Patrol's duty to guard the southwestern 

 southern and southeastern limits of all ice in the vicinity of the Cxrand 

 Banks. Other factors taken in account were the ice distribution, 

 meterological conditions, ocean currents and sea temperature con- 

 ditions.

COMMUNICATIONS 



The collection, plotting, and analysis of ice reports would not be of 

 much value unless the ice information were dissemmated to shippmg. 

 The primarv means for dissemination are the twice daily broadcasts 

 of ice buUetins to shipping by U.S. Coast Guard radio station (\1K), 

 Argentia, Ne^^^oundland. Twice daily broadcasts of ice conditions 

 were transmitted simultaneously at 0048 and 1248 Greenwich mean 

 time on 155, 5320 and 8502 kc/s commencing 6 March and termmating 

 22 June. Also twice daily ice reports were forwarded to the L_b. 

 Hydrographic Office, the Canadian Department of Transport ice 

 Central, Halifax, and others for further dissemination by them. 1^ or 

 the first time, ice charts were successfully broadcast to shippmg by
