included in the U.S. Marine Information Broadcast for the 

 High Seas of the North Atlantic, a voice broadcast origina- 

 ting from the U.S. Coast Guard Communications Station 

 Boston/NMF. A facsimile ice chart was broadcast from Boston 

 once each day. Iceberg information was also included on the 

 regularly scheduled radio facsimile broadcasts of Naval 

 Radio Norfolk/NFAX, CANMARCOM/CFH, Radio Bracknell/GFE, Radio 

 Hamburg/DGC and Radio Quickburn/DGN. 



The U.S. Coast Guard Cutter EVERGREEN, Commanded by 

 Lieutenant Commander Martin J. MOYNIHAN, U.S. Coast Guard, 

 conducted oceanographic cruises for the Ice Patrol during 

 3-26 April, 8-29 May and 13 June - 14 July. Approximately 

 13 days of the final cruise were devoted to a special survey 

 that provided field data and verification to the Labrador 

 Current model developed by Commander Ronald C. KOLLMEYER, 

 U.S. Coast Guard. This may become a useful input to the 

 iceberg drift program. 



For the second consecutive year a surface patrol was 

 required. USCGC HAMILTON, commanded by Captain James H. 

 SWINT, U.S. Coast Guard, assumed the first Surface Patrol 

 duties on 10 March while enroute home port after completing

 17 March and the following cutters continued the surface
