which the Acushnet had k^ft on tho 19th was relocated on the 20th 

 in 45°58' N., 48°39' W. This berg was tracked until the 23d when 

 the visibility had improved to such an extent that a search was made 

 along the eastern edge of the Banks to 45°13' N., 48°29' W., and 

 back to the berg again in position 44°42' N., 48°32' W. By the 26th 

 this berg had been reduced to the size of a growler in 44°25' N., 

 48°36' W. An attempt was made on the 27th to make a search to 

 the northward but the fog became so dense that the vessel was forced 

 to return to the vicinity of the growler. By the afternoon of the 28th 

 the growler had been reduced to such a small size that it was difficult 

 to keep track of it in the rising gale. It was estimated that it would 

 not last 24 hours so the Tampa left it and steamed slowly south- 

 westward to ride out the gale. 



Weather conditions improved on the 29th and the seas moderated 

 sufficiently to allow a ladder search to be commenced northward along 

 the 100-fathom curve on the eastern edge of the Grand Banks until 

 nightfall when the ship was stopped and drifted in the vicinity of 

 44°45' N., 48°30' W. During the 30th a search was made for the 

 berg reported 26 May in 46°50' N., 48°20' W. After searching the 

 area between latitudes 45°35' N., to 46°55' N., and between longitudes 

 48°25' W., and 47°30' W., with negative results the Tampa stopped 

 and drifted for the night. The 31st of May and the 1st of June were 

 spent in trying to locate the berg sighted by an ice patrol plane 30 

 May in 46°38' N., 49°20' W. The berg was located the afternoon 

 of the 1st in 46°26' N., 48°52' W. For the rest of day and all of 2 

 June the Tampa drifted with this berg which continually calved 

 growlers and smaller bits of ice. Early on 3 June the Tampa set a 

 course to the westward to meet the Acushnet who relieved her that 

 same morning. The Tampa then returned to Argentia arriving there 

 on 5 June. 



Only one gale occurred on this cruise and that was the one expe- 

 rienced 28 May. Fog was present 49 percent of the time which is 

 greater than the average as shown on the Pilot Chart of the North 

 Atlantic for May 1950. Weather observations and reports were 

 confined to six hourly synoptic weather reports. 



Following is a summary of water temperature and ice reports 

 received on this cruise: 



Number of ice reports received 392 



Numyjer of vessels furnishing ice reports 86 



Number of water temperature reports received 371 



Numt)er of vessels furnishing water temperature reports 86 



Number of vessels furnished special information 30 



A discussion of the 12 ice observation flights made during this 

 cruise is contained in the description of ice conditions for May and 

 June.
