The weather was rather mild. The prevailing winds were from the 

 southeast to the southwest with force 3. The wind attained a force 

 of 6 on two different occasions and lasted only for a few hours each 

 time. No scouting could be done on five days on account of fog. 

 The percentage of time with visibility less than 2 miles was 29 per 

 cent.

FIFTH CRUISE, "TAMPA," JUNE 2 TO JUNE 17, 1932 



The Tam])a sailed from Halifax at 12.30 p. m. May 30, 1932. The 

 Pontchartrain was contacted in 42° 56' N., 53° 09' W., at 8 a. m. 

 June 2. The ice observation party reported aboard, and the Tampa 

 relieved the Pontchartrain as ice-patrol vessel. The Pontchartrain 

 then proceeded to port. 



The ice-patrol vessel scouted to the eastward until dark. A berg 

 was found at 6 p. m. in 42° 41' N., 51° 33' W., which proved to be the 

 same berg sighted by the Pontchartrain at noon the day before. On 

 June 3 the Tampa continued to scout to the eastward. Fog prevented 

 searching operations for three hours during the forenoon. The ice- 

 patrol vessel located the berg first reported in 42° 54' N., 49° 55' W., 

 on May 31, now in 42° 27' N., 50° 11' W. From this berg the Tampa 

 scouted to the northeastward until dark. 



On the morning of June 4 the berg sighted the afternoon before was 

 relocated. Then the ice-patrol vessel scouted to the westward to re- 

 locate the berg sighted on June 2. On June 5 the Tampa scouted to 

 the southward for 30 miles and then to the eastward parallel to and 

 just north of the westbound steamer lane then in use. The berg last 

 sighted on June 2 was found in 41° 55' N., 50° 30' W., at 4.45 p. m. 

 Its drift had curved from west to southeast. 



Low visibility and fog prevented searching during the morning of 

 June 6. In the afternoon the Tampa relocated the berg sighted the 

 afternoon of the previous day. June 7, 8, and 9 were spent drifting 

 in a dense fog. The fog cleared at 10.20 a. m. on June 10 and the ice- 

 patrol vessel scouted to the eastward along the probable path of the 

 berg last seen on June 6. June 11 was foggy. 



June 12 the Tampa searched to the westward just north of the west- 

 bound steamer lane. The westward search was continued on June 

 13 until the meridian 51° 30' W. was reached. Then the search was 

 changed to the eastward on a line 20 miles north of the westward
