POST-SEASON CRUISE, "GENERAL GREENE," JULY 22 TO AUGUST 



17, 1938 



The General Greene departed St. Jolm's, Newfoundland, at 1517, 

 July 22, 1938. The Pontchartrain was met in St. John's Bay, just 

 outside the Narrows, and Lt. W. P. Hawley, commander, post-season 

 observation cruise, and the ice observation officer reported aboard, 

 and the General Greene departed immediately on the post-season 

 cruise. The purpose of this cruise was to continue the oceanographic 

 investigation of the general region of the Labrador Sea and Davis 

 Strait and to observe ice conditions on the Greenland, Baffin Land, 

 and Labrador coasts. 



Course was set northward from St. John's along the coast to South 

 Wolf Island, Labrador, where, at 1340, July 24, the first of a line of 

 oceanographic stations extending from that place across the Labra- 

 dor Basin to Cape Farewell, Greenland, was occupied. This section 

 consisted of 22 stations, at each of which, as usual, serial observations 

 of temperature and salinity were obtained at various levels from 

 surface to bottom. This run was successfully completed at 1306, 

 July 28, with the occupation of a station 10 miles south of Cape 

 Farewell, heavy field ice preventing closer approach to the coast at 

 that point. While occupying station number 2827 on July 28 in 635 

 fathoms of water the wire carrying the water bottles and thermom- 

 eters parted, at a point where the wire had been injured earlier in the 

 season, with the loss of the following equipment: 5 Nansen water 

 bottles, 3 unprotected thermometers, 7 protected thermometers, 6 

 messengers, and 3,589 feet of wu-e rope. The loss of the three unpro- 

 tected thermometers slowed operations somewhat but sufficient 

 equipment remained to continue the program. The next portion of 

 the cruise was a line of 8 stations which, together with one station 

 in the center of the Cape Farewell section, formed a line of 9 stations 

 running up the middle of the Labrador Sea from deep water to the 

 top of Davis Strait Ridge. At these stations, beside the regular 

 observations for density determination, samples were collected from 

 the deeper layers for the determination of dissolved helium and oxy- 

 gen. From the end of this section on the Davis Strait Ridge in 

 latitude 65°38' N., longitude 57°43' W., a line of stations was occu-
