Continuing into the first week in January the berg near Cape Race on 

 29 December was relocated on 3 January at 45°50' N. 52°35' W. Two 

 bergs also were sighted that day at 45°30' X. 49°15' W. and 45°45' N. 

 48° \Y . These reports make it probable that at least three bergs arrived 

 south of latitude 48° X. in December. Such berg activity this month is 

 most unusual but seems related to the abnormal occurrence of icebergs 

 off northern Newfoundland in October and November. 



ICEBERG DRIFTS 1959 



On Figure 15 are plotted 2!) selected drift tracks of icebergs observed 

 during the ice season. These drifts were chosen as neither the largest bergs 

 nor the most extreme drifts, but because conditions permitted the posit ive 

 identification from one sighting to the next. From several reports re- 

 ceived of the same berg during a day the one thought most reliable or the 

 mean position was used. 



UNUSUAL ICE SIGHTINGS 1959 



Though the International Ice Patrol area of operations is limited to the 

 vicinity of the Grand Banks of Newfoundland, it maintains an interest in 

 ice information and sightings the world over. Mariners and other inter- 

 ested agencies are invited to communicate with Commander, Internationl 

 Ice Patrol in a discussion of sea ice and iceberg conditions. 



The following table presents a listing of unusual ice sightings in the 

 North Atlantic Ocean received by the Ice Patrol during 1959. By "un- 

 usual" is meant ice reported to be outside the commonly accepted extreme 

 limits appearing in the United States Navy Hydrographic Office Ice 

 Atlas of the Northern Hemisphere and on pilot charts. 



ICEBERG DEMOLITION EXPERIMENTS 1959 



The 1959 season marked a renewed activity by the International Ice 

 Patrol toward a means of artificially inducing or accelerating the de- 

 struction of an iceberg through disintegration or melting. Since its be-
