The work of collection of data began on the mornmo; of 26 April and 

 progressed from north toward south. The first section had not been 

 completed when it was necessary to heave to on account of weather 

 at midnight on the first day. After 15)2 hours, oceanographic work 

 was resumed. No other major interruptions occurred and the collec- 

 tion of data was completed on the afternoon of 8 Alay. This survey 

 was made up of 83 stations. The Evergreen then proceeded to a point 

 about 100 miles southeasterly of the Tail of the Banks, where a carbo^^ 

 of surface water was collected for use as a substandard of salinity 

 during subsequent surve3's. A course was then laid for Ai'gentia 

 where the Evergreen arrived on the morning of 10 May. 



The Evergreen departed Argentia on the morning of 28 May to 

 begin a third survey. The planned survey had the same northern 

 limit as the second survey but had a western boundary of 50°15' W., 

 and extended fartlier seaward than usual in the hope of developing 

 information as to the extent of the colder mixed-water salients which 

 were known to exist south-southeastward of the Tail of the Banks 

 and southward of Flemish Cap. The work of collection of data began 

 at noon on 29 May and work progressed from south towards north. 

 On 6 June the survey work was interrupted to intercept the U. S. C. G. 

 Cutter Matagorda to effect the emergency transfer of two men for 

 transportation to Boston. Work on the survey was resumed on the 

 early morning of 7 June. It was not necessary to heave to on account 

 of gales during this survey. No further interruptions occurred, and 

 the work of collection was completed on the afternoon of 11 June, 

 the survey including 90 stations. The Evergreen then proceeded to 

 Argentia. arriving there on the afternoon of 12 June. 



A fourth survey was begun with the departure of the Evergreen 

 from Ai'gentia on the morning of 21 June. This survey was intended 

 to include the waters over and immediately seaward of the northern 

 and northeastern slopes of the Grand Banks and the Flemish Cap 

 area northward of about 46°50' N., and eastward to about 43°30' W. 

 The work of collection of data began on the evening of 22 June at the 

 offshore corner of the Bonavista triangle and progressed counter- 

 clockwise around the triangle, after which a network was occupied 

 working southeastward to the final station which was completed on 

 the afternoon of 2 July. It was not necessary to heave to on account 

 of gales at any time, nor were there any other interruptions during 

 the survey. From the final station the Evergreen proceeded to a point 

 about 75 miles southeastward of Flemish Cap, where a carboy of 

 surface water was collected for subsequent use as a substandard of 

 salinity. The Evergreen then proceeded to Boston, arriving there on 

 the afternoon of 7 July. During this survey 95 stations were occupied. 



The Evergreen departed Boston on 15 July to begin the postseason 

 cruise. En route to the first station, when off Trepassey Bay, New- 

 foundland, an electrical fire in the main propulsion motor disabled
