Greene steamed eastward along the track until the American plane 

 passed over, bound east, and headed on course 167° true so as to be 

 as near as possible the course Ime of the English plane, which was 

 flying rhumb line, about 100 miles south. At 0710 July 6, both planes 

 having successfully completed the trans-Atlantic crossing, the General 

 Greene headed for Flemish Cap to resume the oceanographic work of 

 the post-season cruise. 



The first station of the second leg of the post-season cruise was 

 occupied in latitude 46°58' N., longitude 44°54' W., at 0202 July 7. 

 From tliis position the General Greene ran the courses and occupied 

 the stations shown on the chart. (See fig. 45.) While occupying 

 station number 2529 on July 9, the wire carrying the bottles and 

 thermometers parted and 3,995 meters of wire, 6 sea water bottles, 

 12 thermometers, 2 weights, and 6 messengers were lost. The loss of 

 this equipment made it impossible to continue observations from 

 surface to bottom but sufficient spare wire and other equipment was 

 on hand to continue the cruise taking observations to 2,000 meters. 

 On July 13 upon arrival at station number 2541 the timing gear of the 

 starboard auxiliary motor, supplying power to the oceanographic 

 winch, carried away and could not be replaced or repaired. With the 

 breakdown of this equipment it was necessary to discontinue the 

 oceanographic cruise. Course was set for St. John's, Newfoundland, 

 and the General Greene arrived there at 1700, July 15, 1937. 



During the period of the post-season cruise, June 19 to July 25, 

 the ice situation was as follows: Reports from the Cape Race area and 

 along the Newfoundland east coast continued during the latter part of 

 June and then diminished rapidly until a cessation of ice reports from 

 this region on July 6 showed that the bergs there at last had disinte- 

 grated and no more were moving in to take their place; the reports 

 from the Belle Isle area continued to show, throughout the period 

 numerous bergs in scattered positions extending eastward from Belle 

 Isle along the track to longitude 50° W., and west of Belle Isle, in the 

 straits, to Point Amour, this is a normal situation and will continue 

 for sometime; about July 9 bergs began to be reported about 180 miles 

 northeast of Cape Race, just outside the 100 fathom curve, and re- 

 peated reports from July 12 to 22 showed these bergs moving south- 

 ward in that area which had been clear of bergs since June 11. It is 

 interesting to note that the last report from the Cape Race area pre- 

 ceded the appearance of bergs in the eastern branch of the Labrador 

 Current by three days, which indicates a relation between the two and 

 possibly a complete change in conditions. In considering possible 

 explanations for this problem it will be interesting to consider the de- 

 partures from normal of the wind force and direction, pressure dis- 

 tribution, during this period and also the results of the post-season 

 oceanographic observations compared with last current map.
