Operations were suspended for 25 hours from the early morning of the 

 14th until the early morning of the 15th while the Evergreen rode out a 

 gale near 44° N., 45° W. No further sections were run into the shallow 

 water of the Grand Banks and the survey was concluded with a section 

 northward onto Flemish Cap. The last BT cast was made here on the 

 afternoon of the 15th and the ship headed SSW while a rendezvous was 

 arranged for the delivery of the current map to the Mocoma, the cutter 

 on patrol. The map was completed on the evening of the 15th. Shortly 

 after completion of the survey, wind and sea began to make up and 

 heavy weather did not permit contact with the Mocoma until the morning 

 of the 17th at 45°02' N., 46°34' W. After dehvering the map, the 

 Evergreen laid a course for Argentia, taking an additional BT section 

 across the Labrador Current enroute and arriving at Argentia the morn- 

 ing of 19 May. 



One of the winch motors had been damaged beyond the possibility of 

 local repair. However, with the other motor repaired, the Evergreen 

 departed Argentia on the morning of 8 June to make a current survey 

 of the area immediately seaward of the eastern slope of the Grand Banks 

 from about latitude 46° N., southward to the Tail of the Banks. The 

 work of the collection of data began on the morning of 10 June at station 

 3617 located at 46°16' N., 49°01' W. Except for brief delays at stations 

 3635 and 3648, caused by kinks in the wire resulting from earlier capstan 

 handling, work proceeded without incident until the earh^ morning of 

 the 18th when at station 3658 located at 41°58' N., 47°46' W., the winch 

 motor failed while hauling in the deep series. The 1600 meters of wire 

 and attached equipment were hauled in with the capstan and a course 

 laid for Argentia, the resulting current map to be delivered to the Mendota 

 there as she was scheduled to depart 21 June to relieve Mocoma as ice 

 patrol vessel. 



The ice season was rapidly drawing to a close and by the time the winch 

 motor was repaired the Evergreen was ready to begin her post-season 

 cruise. After leaving Argentia on the evening of 4 July, the first station of 

 the post-season cruise, station 3659 at 50°00' N., 49°00' W., was reached 

 on the morning of 6 July. From this point a series of three sections, 

 forming the sides of a triangle, were run to Cape Bonavista, Newfound- 

 land, thence to 47°24' N., 50°01' W., and thence to the beginning where 

 the initial station was reoccupied as station 3688 on the morning of the 

 10th. From this point a course was laid to South Wolf Island, Labrador, 

 from which a section was run across the Labrador Sea to Cape Farewell, 

 Greenland, with the occupation of stations 3689 to 3711 inclusive between 

 the afternoon of the 11th and the early morning of the 17th. During 

 this run it was necessary to suspend operations from the morning of the 

 15th until the afternoon of the 16th while the Evergreen rode out a gale 

 in the vicinity of 59° N., 45° W. From Cape Farewell the Evergreen 

 proceeded to station 3712, located at 58°57' N., 54°28' W., which was the 

 southern end of a longitudinal section nni northward across Davis Strait
