It had drifted arouud the Tail of the Banks a distance of 60 miles 



since last seen. The Tampa remained near this berg until relieved 



by the Modoc at 6 a. m., June 8, in latitude 42° 58' N., longitude 



54° 14' W. 



Resume 



During the third cruise of the Tampa 850 temperature reports were 

 received. In response to 2 requests for medical attention the ship's 

 doctor prescribed, the vessels reported their patients doing well after 

 a lapse of 3 days and thanked the patrol vessel. Thirty-nine requests 

 for ice information were answered. Eight special ice broadcasts were 

 sent out in addition to the regular broadcasts. Three obstruction 

 reports were received and broadcast. Eighteen weather reports 

 were transmitted to passing shipping; 92 ice reports were received 

 from vessels, and 59 reports from shore stations. 



WEATHER 



(See Charts Nos. 12, 13, and 16) 



The weather experienced during this cruise was not very good 

 for the work outlined. Only two gales were encountered, but con- 

 siderable fog and rain prevailed. 



TEMPERATURES 



(See Charts Nos. 12 and 13) 



Warming up of the water masses in the patrol area had progressed 

 to such extent that no Arctic water was reported south of the forty- 

 eighth parallel. Surface temperatures over the northern and north- 

 eastern slopes of the Banks ranged from 35° to 40°, while over the 

 central portions of the Banks they were well over 40°. The GuH 

 Stream had moved slightly to the northward. Of particular interest, 

 as affecting the drift of bergs, was a narrow tongue of 36-40° water 

 lying along the eastern slope and extending as far south as the Tail 

 of the Banks. During the early part of the period the bergs in their 

 southerly drift all stopped upon reaching the neighborhood of lati- 

 tude 44° 30' N. and recurved to the northeastward, but toward the 

 end of the period berg No. 14 came under the influence of the tongue 

 of cold water extending southward and was carried down to the Tail 

 of the Banks where its movements were watched with interest. The 

 past developments of the cold tongue afforded valuable information 

 relative to the drift of the bergs along the northeastern slopes of the 

 Banks; thus should the tongue be pinched off by warmer currents it 

 seemed probable that the southerly movement of the foregoing bergs 

 would be greatly diminished. A tongue of cold water about 38° 

 extended about 25 meters below the surface of the water. This was 

 probably the propelling force of the bergs.
