36' W., and the ice-observation party duly transferred to the relieving 

 vessel, and the Tampa proceeded to Halifax for fuel and supplies. 



By April 8 the limits of the ice area were well defined by reports 

 from cooperating ships to be north of latitude 45° 20' N, and west of 

 longitude 46° 00' W. The most ice-congested area was between 

 latitudes 45° 20' N. and 46° 30' N., and longitudes 48° 00' and 49° 

 00' W., where numerous bergs, growlers, and field ice had been re- 

 ported. The bergs reported were small, with many growlers near 

 them, indicating that they probably were old bergs that did not 

 complete their journey south last year. Continued south and 

 southeast winds kept this ice from drifting south as fast as normally 

 would be expected. 



On April 13 the southernmost ice was a berg in 45° 00' N., 48° 

 45' W. Continued fog and low visibility had greatly hindered the 

 scouting operations of the ice-patrol vessel, but with the cooperation 

 of several vessels that passed through the ice regions the limits of the 

 ice were kept well defined at all times. By April 13 bergs were re- 

 ported well within 50-fathom curve and were numerous along the 

 Canadian track E now in use as far west as the turning point. Two 

 bergs were in the center of the Banks near 45° 30' N., 51° 40' W. 

 After this date a warning to proceed with caution when north of 

 latitude 44° 30' N. and between longitudes 46° 00' and 51° 00' W. 

 was included in the broadcasts. On April 14 and 15 no searching 

 could be done on account of fog and no reports of ice were received 

 by radio. 



The weather generally was mild, with south and southeast breezes 

 prevailing. The visibiHty was remarkably poor throughout the 

 entire cruise. The percentage of time with visibility of less than 2 

 miles was 56.5. 



A total of 56 ice reports were received during the patrol from 13 

 different ships. Besides the regular broadcasts ice information was 

 furnished seven vessels. Sea-water temperatures were received from 

 121 different vessels, furnishing a total of 628 reports. A detailed 

 picture of ice conditions and surface isotherms is shown on Figure 1. 



SECOND CRUISE, "PONTCHARTRAIN," APRIL 18 TO MAY 3, 1932 



The ship being in all respects ready for sea, proceeded at 2.05 p. m. 

 April 14 for the Grand Banks. The weather held fair, wind general 

 and variable until the morning of April 16, when a southeast gale 

 was encountered. At 8.10 a. m. slowed to 10 knots. At 12 noon 

 hove to at 70 revolutions. Remained hove to for 24 hours. Sea 

 continued rough. Made first contact with the Tampa at 10.45 p. m, 

 April 17. The sea was too rough for effecting transfer. Hove to on 

 several courses until noon next day. At 12.20 p. m. April 18, the 

 Tampa's boat came alongside. Lieut. R. M. Hoyle and Chief
