Table 5. Iceberg and Sea Surface Temperature Reports. 



The IIP prepares the ice 

 bulletin warning mariners of the 

 southwestern, southern, and 

 southeastern limits of icebergs 

 twice a day for broadcast at OOOOZ 

 and 1200Z. The IIP also prepares 

 a facsimile chart graphically 

 depicting these limits for broadcast 

 at 1600Z. U.S. Coast Guard 

 Communications Station Boston, 

 Massachusetts, NivlF/NIK, was the 

 primary radio station used for the 

 dissemination of the daily ice 

 bulletins and facsimile charts . 

 Other transmitting stations for the 

 OOOOZ and 1200Z ice bulletins 

 were Canadian Coast Guard 

 Radio Station St. John's/VON, Ca- 

 nadian Forces Meteorological and 

 Oceanographic Center (METOC) 

 Halifax, Nova Scotia/CFH, and 

 U.S. Navy LCMP Broadcast 

 Stations Norfolk/NAM; Thurso, 

 Scotland; and Keflavik, Iceland. 



Canadian Forces METOC, 

 Halifax/CFH, as well as AM Radio 

 Station Bracknell/GFE, United 

 Kingdom, are radiofacsimile 

 broadcasting stations which used 

 Ice Patrol limits in their broad- 

 casts. Canadian Coast Guard 

 Radio Station St. John's/ VON and 

 U.S. Coast Guard Communica- 

 tions Station Boston/NIK provided 

 special broadcasts. 



The International Ice 

 Patrol requested that all ships 

 transiting the area of the Grand 

 Banks report ice sightings, 

 weather, and sea surface tem- 

 peratures via the above communi- 

 cations/radio stations. Response 

 to this request is shown in Table 5. 

 Appendix A lists all contributors. 

 Commander, International Ice 

 Patrol extends a sincere thank you 

 to all stations and ships which 

 contributed. 



For the first time, IIP was 

 directly linked in 1988 to Canadian 

 Coast Guard Radio St John's/ 

 VON, Ice Operations St. John's, 

 Ice Centre Ottawa, and the 

 offshore oil industry via an elec- 

 tronic mail system with telex as a 

 backup. Canadian Radio Station 

 St John's/VON passed all iceberg 

 sighting reports it received to IIP 

 via Ice Operations St. John's. Ice 

 Operations St John's converted 

 the iceberg sighting report to the 

 computer compatible joint AES/IIP 

 iceberg code. This ensured better 

 accountability and more timely 

 receipt of the iceberg sighting 

 reports. IIP and AES reconnais- 

 sance detachments have been 

 using the computerized code since 

 the 1986 season. The offshore oil 

 industry conducts aerial ice 

 reconnaissance in the vicinity of oil 

 exploration on the Grand Banks. 

 Their sighting reports are transmit- 

 ted directly to Groton.
