in favor of the region south and southeast of the Tail of the Grand 

 Banks. 



Accordingly the work of collection of data was begun at station 

 2954, located at 42°00' N., 51°00' W., on May 21 and progressed 

 from west toward northeast. The first part of the survey was com- 

 pleted without incident at station 2978, located at 42°24' N., 45°51' 

 W., on May 27. The current map resulting from these observations 

 was completed 1 1 }^ hours later and was delivered aboard the Champlain 

 the morning of May 28. The survey could not be repeated because 

 ice and current conditions required that the survey be extended 

 southward instead. Plans were changed accordingly and additional 

 stations were occupied in a strip along the southern and southwestern 

 border of the area originally mapped. Station work was completed 

 at station 2993 located at 4b°25' N., 51°30' W., on June 1, a total of 

 40 stations having been occupied. 



From the stations occupied during the second part of the survey a 

 supplemental map was drawn. This was completed 6K hours after 

 the last station had been completed and was delivered to the Cham- 

 plain on June 2. The General Greene then proceeded to St. John's 

 where she arrived on June 4. 



Departure was taken from St. John's on June 19 for the purpose of 

 making a fourth current survey. This survey extended from about 

 latitude 46° N., to about latitude 41° N. The work of collection 

 was begun at station 2994, located at 46°23' N., 48°53' W., on June 20, 

 the work progressing from north to south. Work was interrupted on 

 June 23 during the occupation of station 3019, when the General 

 Greene was ordered to search for a berg reported in 41°45' N., 48°40' 

 W., until relieved the following day by the Champlain. The berg 

 was located at 1450 on June 24 and the General Greene stood by it 

 until relieved by the Champlain at 2015 when the General Greene 

 proceeded toward the next oceanographic station arriving there and 

 resuming work on June 25. The work of collection of data was 

 completed at station 3048 located at 42°17' N., 50°41' W., on June 

 30, a total of 55 stations having been occupied. The resulting current 

 map was then constructed, being completed and delivered aboard 

 the ChamjJlain on July 1, 13 hours after the last station was occupied. 

 The General Greene then returned to St. Jolui's where she arrived on 

 July 3. 



Thus 201 oceanographic stations were occupied during the ice-patrol 

 season. After completing the last map the General Greene was released 

 from further mapping of the Grand Banks region for a short post- 

 season cruise between southern Labrador and southern Greenland, 

 During this cruise 25 additional oceanographic stations, disposed in 

 the form of a single section from South Wolf Island to Cape Farewell, 

 were occupied from July 10 to July 15. The temperature and salinity
