25 March two flights covered the eastern edge of the Grand Banks 

 from Tail of the Banks to latitude 46° N., and the area between 

 46° and 48°40' N., from the 45th meridian to the Newfoundland 

 coast. On 29 March one flight covered the Strait of Belle Isle, 

 White Bay and Notre Dame Bay, while another flight covered the 

 area between 42°o0' N., and 46^00' N., from the eastern edge of the 

 Grand Banks eastward 70 miles. On 31 March one flight covered 

 the area between 47° N., and the south coast of Newfoundland 

 westward to Cape Ray. On 2 April one flight covered the St. 

 Lawrence ice coming out of Cabot Strait outside of a line from 

 Cape St. George to Cape North, to the outer limits of the ice at 

 the 45th parallel between the 58th and 60th meridians. On the 

 same day another flight covered a 90-mile wide strip along the 

 eastern edge of the Grand Banks from 46°20' N., to 42° N. 



Second Cruise, "Tampa," 3 April to 17 April, 1946 



The Tampa departed from Argentia, Newfoundland, at 1330 

 G. c. t. on 2 April 1946, for ice patrol. The Modoc was met and 

 relieved as surface patrol vessel at 1415 G. c. t. on 3 April 1946. 

 Weather experienced during this cruise included two cyclonic 

 disturbances. Both were traveling to the northeast at approxi- 

 mately 30 miles per hour. The center of the second disturbance, 

 whose efl'ects were felt more than those of the first, passed about 

 50 miles to the northwest of the Tampa and as a result winds of 

 70 miles per hour and heavy seas were encountered for a period of 

 24 hours. In general the weather was steady and the visibility 

 good. 



At 1805 G. c. t. on 17 April 1946, the Modoc relieved the Tampa 

 and the Tampa set course for Argentia, Newfoundland, arriving 

 there on 18 April 1946.

During the period of this cruise the surface patrol vessel activity 

 was supplemented by the following aerial ice observation flights: 

 On 9 April one flight delineated the limits of the St. Lawrence 

 ice outside a line from Cape Anguille to Cape Canso, the limits 

 following approximately the 45th parallel and the meridian of 

 58°40' W. On 15 April one flight was made along the parallel of 

 47°30' N., from Newfoundland to the eastern edge of the Grand 

 Banks, and a second flight covered a 100-mile wide strip along the 

 eastern edge of the Grand Banks from 42°30' N., to 45° 40' N. On
