The search was continued until 11 May when a small berg was sighted 

 in 46°57' N., 47°28' W. A course was then set for the Flemish Cap 

 area to investigate numerous reports of bergs in that area. 



A small berg about 50 feet high and growler were sighted in 46°56' 

 N., 47°29' W., on 11 May. After the vicinity of Flemish Cap was 

 reached, a search was made along the 100-fathom curve but no ice was 

 sighted. The Acushnet then headed westward to search the area north 

 of the Grand Banks. That night a radar target was identified at a 

 distance of 1 mile by use of searchlight in 46°45' N., 47°19' W., as the 

 berg sighted 11 May in 46°56' N., 47°29' W., having drifted 140° T at 

 approximately 11 miles per day. Bergs were sighted 13 May in 47°42' 

 N., 47°58' W., and 47°56' N., 48°35' W. Visibility continued good 

 throughout 14 May as the ship proceeded south to the Grand Banlvs. 

 After rendezvousing with the Evergreen to obtain the current chart on 

 15 May in vicinity of 45°00' X., 48°30' W., course was set northeast- 

 ward to search for the berg previously reported 12 May. This berg 

 was relocated 16 May in 45°56' N., 47°35' W. On 17 May an 

 attempt was made to locate a charted 7-fathom shoal in 45°42' N., 

 48°16' W., but no sounding less than 90 fathoms was obtained after 

 crossing the position three times. The Acushnet relocated the berg 

 sighted on the 12th on 18 May in 45°27' N., 48°20' W., and drifted 

 with this berg until the 19th. The Acushnet was relieved by the 

 Tampa 19 May, and course was set for Argentia where the Acushnet 

 arrived 20 May.

Fourth Ice-Patrol Cruise, "Tampa," 78 May to 5 June 1950 



The Tampa left Argentia 18 May and proceeded to the vicinity of 

 the Tail of the Grand Banks and relieved the Acushnet on 19 May.
