Data Collection and Dissemination 



During the 1982 Ice Patrol Fiscal year (considered from 1 

 September 1981 through 30 September 1982), 118 aircraft 

 sorties were flown in support of the International Ice Patrol. 

 These Included pre-season flights, ice observation and 

 logistics flights during the season, and post-season flights. 

 Pre-season flights determined iceberg concentrations 

 north of 48°N which were necessary to estimate the time 

 when icebergs would threaten the North Atlantic shipping 

 lanes in the vicinity of the Grand Banks of Newfoundland. 

 During the active season, ice observation flights located 

 the southwestern, southern, and southeastern limits of 

 icebergs. Logistics flights were necessary to rotate ice 



reconnaissance detachment personnel and for unusual air- 

 craft maintenance. Post-season flights were made to 

 retrieve parts and equipment from Gander and to close out 

 all business transactions from the season. Table 2 shows 

 aircraft utilization during the 1982 season. 



U. 8. Coast Guard C-130 Aircraft, deployed irom Coast 

 Guard Air Station Elizabeth City, North Carolina, conducted 

 the aerial ice reconnaissance. These aircraft operated from 

 Gander, Newfoundland, for the first time. This proved to be 

 operationally and financially superior to operating out of 

 St. John's as in previous years. Weather conditions at 

 Gander allowed more consistent flight operations at lower 

 fuel costs.

"Prior to the 1982 Ice Patrol Season, the Ice Patrol's annual bulletins covered the period from 1 September to 30 August of 

 the following year. This period was extended an additional month in 1982 to reduce the probability of an ice season carry- 

 ing over into the following year and to correspond with the fiscal year which begins on 1 October. 



U. S. Coast Guard Communications Station Boston, 

 Massachusetts, NMF/NIK, was the primary radio station 

 used for the dissemination of the daily ice bulletin and fac- 

 simile chart after preparation by the Ice Patrol office in New 

 York. Other transmitting stations included Canadian Coast 

 Guard Radio Station St. John's/VON, Canadian Forces 

 Radio Station Mill Cove/CFH, and U. S. Navy LCMP Broad- 

 cast Stations Norfolk/NAM, Thurso, Scotland, and Keflavik, 

 Iceland. 



Canadian Forces Station Mill Cove/CFH as well as AM 

 Radio Station Bracknell/GFE, United Kingdom are radio 



facsimile broadcasting stations which used Ice Patrol 

 limits in their broadcasts. Canadian Coast Guard Radio 

 Station St. John's/VON provided special broadcasts. 



The International Ice Patrol requests all ships transiting 

 the area of the Grand Banks to report ice sightings, 

 weather, and sea surface temperatures via U. S. Coast 

 Guard Communications Station Boston, NMF/NIK. 

 Response to this request is shown in ''ible 3. Appendix A 

 lists all contributors. Commander, International Ice Patrol 

 extends a sincere thank you to all stations and ships which 

 contributed.
