Sailing-, orig-inally planned for 27 April, was postponed until the 

 following day while a gale blew itself out. It was expected, 

 therefore, that at least the first part of the sui^vey could be carried 

 out with quiet weather. This proved to be unwarranted optimism. 

 The work of collection of data began at station 4386, located at 

 49°58' N., 48°58' W., on the afternoon of 29 April. At 1016 the 

 following day it was necessary to heave to on account of weather. 

 Operations were resumed at 0438 on 1 May. At 0746 on 1 May 

 oceanographic work was interrupted while the Evergreen pro- 

 ceeded toward Fogo Island to assist in locating a man reported 

 adrift on the ice. Oceanographic work was resumed 9 hours later. 

 At 2135 on 3 May it was necessary to heave to again on account 

 of weather, this time for 71/2 hours. Weather again forced an 

 interruption of the work on 8 May when the ship was hove to from 

 1251 to 1826. These interruptions do not tell the complete story 

 of the boisterous weather which was a succession of gales. Of the 

 79 stations occupied, 19 were occupied in winds of force 6 or 

 greater, including 4 with force 8. The final station of the survey, 

 number 4464, located at 46°47.5' N., 44°51' W., was completed on 

 the morning of 10 May. The Evergreen then proceeded to pick 

 up a carboy of water at 45°41.5' N., 44°39' W., for use as a sub- 

 standard of salinity. A course was then set for Argentia with 

 arrival there on the morning of 12 May. 



The Evergreen departed Argentia on the evening of 21 May to 

 make a third current survey of the Grand Banks region. This 

 survey was planned to cover the waters over and immediately sea- 

 ward of the eastern and northeastern slopes of the Grand Banks, 

 including occupations of sections T, U, and W, and extending to 

 the area just northward of the latitude of Flemish Cap, with the 

 work beginning at the southern end of the area and progressing 

 northward. Accordingly the work of collection of data began at 

 station 4465, located at 43°20' N., 50°15' W., on the early morning 

 of 23 May. There was a delay of an hour and a half on the evening 

 of 31 May while a defective electrode cable for the von Arx current 

 meter was replaced. At 1136 on 3 June, after completion of sta- 

 tion 4553, it was necessary to heave to an account of weather. 

 Work was resumed at station 4554 at 0350 on 4 June. No further 

 interruptions occurred and the work of collection of data was com- 

 pleted at station 4559, located at 47°13' N., 49°18' W., on the 

 afternoon of 4 June. The Evergreen then proceeded to Boston, 

 arriving there on the evening of 7 June. 



Since the ice observation and ice patrol services had been dis- 

 continued for the season on 24 May because of the absence of ice 

 in positions of potential hazard to shipping, no further current 

 surveys of the Grand Banks area were made. The post-season
