Then at 8:05 p.m. the same day the first station of the last section 

 across the Labrador current terminating at the coast near Domino 

 Run was occupied. The section was completed at 4:40 p.m. on July 

 24. The coast was not sighted because of low visibility. This com- 

 pleted the oceanographic program for the cruise. 



We laid a course for St. John's, Newfoundland, arriving there at 

 0:40 a.m. July 27. After receiving commissary stores, fuel, and 

 water, we sailed for Boston, Mass., at 9:45 a.m., July 28. We arrived 

 in Boston at 5:40 a.m., August 3, 1933. 



The oceanographic program was carried out as planned, with the 

 exception of the stations omitted on account of the ice conditions on 

 the Labrador coast. Soundings were taken every 20 minutes with 

 the fathometer, except when water noises, vibration of vessel, and 

 depth of water prevented the return echo from being heard. Surface 

 temperatures were taken every 2 hours. 



The weather for the first half of the cruise was rather boisterous. 

 While most of the days were overcast, observations of the sun could 

 be obtained through the clouds for positions on all but 4 days on 

 the run to Ivigtut, Greenland. On the run across Davis Strait from 

 Ivigtut, the weather was bright and clear with smooth sea. After 

 a few hours of fog the fine weather continued until we left Cape 

 Harrison on July 21. Low visibility prevailed with occasional clear- 

 ings in which observations were obtained for positions during the 

 rest of the cruise. 



WEATHER 



The weather conditions experienced by the General Greene are 

 shown by the accompanying diagrams (figs. 2-5) . Due to the abnormal 

 ice conditions these observations were taken somewhat further north 

 than is usual on the regular ice patrol. Latitude 46° N., longitude 49° 

 W., can be taken as a mean position of the observations except on 

 the northern oceanograpliic cruise. While on ice observation duty 

 the General Greene actually remained within 2° of latitude and 3° of 

 longitude of this position. However, it must be borne in mind that 

 this area is a region of strong contrasts in weather conditions due to the 

 influences of both the Labrador current and the Gulf Stream. 



The temperature averages and percentages of fog are only for the 

 days that the General Greene was at sea. 



MARCH 



Maximum air temperature 47° F. 



Minimum air temperature 18° F. 



Average air temperature 33.6° F. 



Visibility was less than 4 miles 16.4 percent of the time. 



Visibility was less than 2 miles 10.9 percent of the time.
