POST-SEASON CRUISE "GENERAL GREENE," JUNE 19 TO JULY 25, 1937 



At 1200, June 19, 1937, the General Greene, being in all respects 

 ready for sea, departed from St. John's, Newfoundland, on the first 

 leg of an oceanographic and ice observation cruise in the interests of 

 the International Service of Ice Observation and Ice Patrol. The 

 purpose of this cruise was an mvestigation of the Labrador and At- 

 lantic Currents and their common boundary and the East Greenland 

 and Irminger Currents as they round Cape Farewell, Greenland, to 

 form the West Greenland Current. To this end the oceanographic 

 sections were planned so as to run, in general, south, southeast, and 

 east from the Grand Banks across the Labrador Current and the At- 

 lantic Current; approximately normal to the direction of flow of these 

 streams. Also one long line of stations from latitude 46°30' N., longi- 

 tude 40° W., across the Labrador Basin to latitude 58° N., longitude 

 45° W., and thence to Cape Farewell, Greenland. This section could 

 not be completed north of latitude 55° N., because of failure of the 

 diesel auxiliary engines. 



Upon clearing St. John's Harbor course 163° true was set for the 

 position of the first station, number 2466, in latitude 41°51' N., 

 longitude 5f)°40' W. From this position the General Greene ran the 

 courses and occupied the stations as shown on figure 45. At 2135, 

 July 1, Headquarters dispatch 6001-1626 was received directmg this 

 vessel to take station along the line of flight of the trans-Atlantic 

 planes, Pan-American and Imperial Air Lines, between Botwood, 

 Newfoundland, and Foynes, Ireland, on July 5 and 6. At this time 

 the General Greene was just south southeast of Flemish Cap and nearly 

 through with the first leg of the cruise so that supplies of fuel and stores 

 were nearly exhausted. In order to be on station along the great 

 circle track 400 miles east of Botwood early on the morning of July 5 

 it was necessary to discontinue the oceanographic program and pro- 

 ceed immediately to St. John's for supplies. This necessitated 

 omittmg the last four stations planned for the first leg of the cruise. 



Course was set for St. John's at 2150 July 1 and the General Greene 

 arrived there at 0902 July 3, 1937. Supplies had been ordered by 

 radio and came aboard during the day. The General Greene departed 

 for the designated position 400 miles east of Botwood along great 

 circle course to Foynes, Ireland, arrivmg at 1037 July 5. The General
