on the 28th so the Tampa set course to relocate this berg. Late on 

 the 29th a dense fog enshrouded the area practically nullifying any 

 search efforts. Visibility improved on the 30th so that the search 

 could once more be resumed and a ladder search was continued on 

 through 1 May when it was secured that afternoon with negative 

 results. The Tampa then returned to the eastern edge of the Grand 

 Banks to search the area between 43°40' N., and 44°30' N., between 

 48°15' W., and 49°10' W. Fog set in once more, effectively curtailing 

 search efforts and persisted through 3 May. Radio relief by the 

 Acushnet was effected on the 3d and the Tampa immediately set 

 course for Argentia arriving there 5 May. 



Weather for this cruise was marked by a lack of fog. During the 

 20 days at sea fog was present for 21 percent of the time. Winds of 

 gale force were experienced on 25 and 27 March but aside from these 

 2 days very little rough weather was encountered. Meteorological 

 observations and reports were restricted to six-hourly synoptic weather 

 reports. 



Following is a summary of water temperature, ice and obstruction 

 reports received on this cruise: 



Number of ice reports received 282 



Number of vessels furnishing ice reports 36 



Number of water temperature reports received 227 



Number of vessels furnishing water temperature reports 70 



Number of vessels furnished special information 25 



A discussion of the 12 ice-observation flights made during this cruise 

 is contained in the description of ice conditions for April and May. 



Third Ice Patrol Cruise, "Acushnet" 2 May to 20 May 1950 



Tl e Acushnet departed Argentia in the evening of 2 May and 

 proceeded to relieve the Tampa on 4 May in vicinity of 44°00' N., 

 50°47' W. After assuming the duties of the ice patrol vessel, a search 

 was begun starting in latitude 43°00' N., and progressing northward 

 along the 49th meridian on the eastern edge of the Banks. Weather 

 conditions from 4 May to 7 May were excellent for visual scouting and 

 enabled the area between 42°30' N., and 45°30' N., to be thoroughly 

 searched visually. The only ice sighted within this area was a 

 growler in 44°23' N., 47°11' W., on 6 May. Many ships reported 

 numerous bergs in the Flemish Cap area at this time as well as large 

 bergs and growlers to the northeastward of the Grand Banks in the 

 vicinity of 47° N. Fog minimized search efforts on 8 May, and it 

 was not imtil 9 May that visibility improved sufficiently to allow the 

 search to be continued northward in the Laljrador Current on the edge 

 of the Grand Banks. The fishing schooner Greenock of Lunenberg, 

 Nova Scotia, was contacted in 4r)°00' N., 49°06' W., on 10 May. 

 No ice had been seen by her in that vicinity. The schooner Freda M 

 of St. Johns, Newfoundland, was hailed nearby and reported all well.
