No report has been received of bergs in area between latitude 45° and 48° N., 

 longitude 46° and 49° W. since June 7. All other ice reported since June 7 has 

 been to eastward of longitude 49°. No water less than 40° F. south of latitude 

 44°. Effect of Gulf stream very noticeable over Banks and surrounding area. 

 Effect of Labrador current no longer noticeable it is beUeved that steamer lanes 

 may be moved to regular position on July 1 with safety. 



Commander International Ice Patrol. 



As fog persisted intermittently, the vessel proceeded at slow speed 

 to the last position of the berg as seen by the Modoc on June 24, and 

 arrived near the reported position of this berg on June 26, but no 

 ice was seen. The area was searched when clear weather permitted 

 and, on June 30 at 1.40 p. m., a small growler was found, the remains 

 of the berg, 443^^ miles, 57° true from the last reported position. 

 This shows a drift of 0.32 knots per hour during that period. The 

 vessel hove to near the growler which rapidly disintegrated. The 

 sonic apparatus was tested on this growler. 



On the evening of June 30 headquarters informed the patrol that 

 the steamship lanes would automatically be shifted on July 1, which 

 information was broadcast to merchant shipping. 



There being no further ice to the eastward, the Tampa headed for 

 the Tail of the Banks to make further search. Fog shut in on the 

 evening of July 1 and the vessel was hove to. After the fog lifted a 

 cruise was made up the east Bank between latitude 43° and 44°, 

 but no ice was seen. 



On the evening of July 2 a recommendation to discontinue the 

 patrol was forwarded to headquarters as follows: 



Coast Guard Headquarters, 



Washington, D. C. 

 No ice known to be north of latitude 47°. This area has been traveled by a 

 number of merchant vessels in clear weather these ships have been in communica- 

 tion with patrol vessel for some time before entering patrol area while crossing 

 area and after leaving area. Two bergs previously reported south of latitude 

 47° have disintegrated. Patrol vessel was alongside of easternmost berg at 

 time of final disintegration. Effect of Labrador current no longer noticeable. 

 No water of less than 47° F. below Tail of Banks. The 60° F. curve has reached 

 latitude 42° 30' N. between longitude 48° and 51° and up to 43° westward of 

 longitude 51° and eastward of longitude 48°. The effects of the Gulf stream 

 are very noticeable over the Grand Banks and the surrounding area prevailing 

 winds from southward sending warm water northward. No new ice report 

 received. In view of the foregoing the discontinuance of the patrol is recom- 

 mended. Critical area has been searched by patrol vessel, no ice seen. 



Commander International Ice Patrol. 



On July 3 a reply was received directing that the area between 

 latitude 42° and 44° N., longitude 49° 30' and 52° W., be searched. 

 The vessel proceeded to the upper section of the area and commenced 

 searching b}^ means of the rectangular search method. On July 

 7 the French barkentine Voalle was spoken, medical assistance was 

 rendered, her position was determined, and fresh food was exchanged
