The work of collection of data was completed, without f mother 

 interruption, on the afternoon of 19 April, at station 4068, located 

 at 46°20.5' N., 48°55' W., and the ship proceeded to contact the 

 patrol vessel {Tainim). In the meantime the data collected were 

 reduced to the form of a current chart. A copy of the current chart 

 "was passed to the Tampa on the afternoon of 20 April, after which 

 the Evergreen proceeded to Argentia, arriving there on the evening 

 of 21 April. 



On 1 May the Evergreen departed Argentia to make a second cur- 

 rent survey of the same general area covered by the first survey but 

 eliminating the southwestern extreme and extending the charted area 

 farther to the northeast. The work of collection of data began on 

 the afternoon of 2 May at station 4069, located at 42°00' N., 51°58' 

 W., and progressed without interruption until the afternoon of 6 

 May when, at station 4093, located at 42°41' N., 46°58' W., deteriorat- 

 ing weather contributed to the loss of some of the oceanographic 

 equipment and then made it necessary to heave to from early eve- 

 ning until early morning on 7 May after which operations were 

 resumed. No further interruptions occurred and the work of col- 

 lection of data was completed early on the morning of 14 May at 

 station 4144 located at 46°48' N., 44°51' W. From this position the 

 Evergreen proceeded to 46°04' N., 45°00' W., where a carboy of water 

 was collected for ultimate use as a substandard of salinity during 

 subsequent cruises. In the meantime work continued on the reduc- 

 tion of the data collected at the 76 oceanographic stations to the form 

 of a dynamic topographic chart, a copy of which was delivered to 

 the patrol cutter (Acushnet) on the morning of 15 May. The Ever- 

 green then proceeded to Argentia where she arrived on the after- 

 noon of 16 May. 



A third oceanographic cruise began with the departure of the 

 Evergreen from Argentia on 26 May. This cruise was for the pur- 

 pose of investigating the oceanographic conditions in the vicinity 

 and immediately northward of the Grand Banks where the Labrador 

 Current divides into a western branch which flows southward along 

 the coast of the Avalon Peninsula of Newfoundland, and an eastern 

 branch which continues southeastward and eventually southward 

 along the eastern edge of the Grand Banks. The oceanographic 

 stations planned were to be disposed as three sections forming the 

 sides of a triangle with corners on the northern edge of the Grand 

 Banks, just off Cape Bonavista, and in the deep water northeast- 

 ward of the first two corners. 



The work of collection of data began on the afternoon of 27 May 

 at station 4145 located at the southern corner of the triangle and 

 progressed counterclockwise around the triangle without interrup- 

 tion until the station at the corner off Cape Bonavista was completed 

 at dusk on 29 May. Numerous icebergs and growlers could be seen
