NORTHERN OCEANOGRAPHIC CRUISE, ''GENERAL GREENE". 



JULY 3 19, 1934 



At 1:37 p. m., July 3, 1934, the General Greene sailed from St. Johns, 

 Newfoundland, on the northern oceanographic and ice-observation 

 cruise. The scientific program consisted in occupying oceanographic 

 stations at various intervals, keeping a continuous thermograph 

 record of the sea-water temperature, and taking soundings every 15 

 minutes with the fathometer unless prevented by water noises or 

 depth of water from hearing the return echo. At each oceanographic 

 station serial temperatures and water samples for determination of 

 the salinity were obtained at various depths from the surface down to 

 the bottom in shoal water and to 2,500 meters in deep water. At 

 2:45 p. m., 6 miles outside St. Johns Harbor, the first oceanographic 

 station was occupied. This began a section of 11 stations 370 miles 

 long running 35° true from St. Johns. 



At 9 a. m. the following morning after completing the fifth station 

 of the section, it was found necessary to return to St. Johns to place 

 a man in the hospital suffering from follicular tonsillitis. The run to 

 St. Johns was made in a dense fog which delayed .our arrival there 

 until 5 a. m., July 5. In St. Johns repairs were made to the fuel-oil 

 pumps and air compressor. After topping off the fresh-water and 

 fuel-oil tanks we sailed from St. Johns at 4 p. m. the same afternoon. 

 The run to the point where the next station was to be occupied was 

 made in a northwesterly gale and rough sea. This station was 

 occupied at 1:04 p. m., July 6. By midnight the wind had moderated 

 to a fresh breeze. However, the sea continued rough until the next 

 afternoon. The first line of stations was completed at 5 a. m., July 8. 



At 10:34 a. m., July 8, we occupied the first station of a section of 11 

 stations which terminated near the Labrador coast at Indian Tickle. 

 The barometer at 4 p.m., which had been falling rapidly all day, reached 

 29:36 and began to rise slowly. However, the resulting winds were 

 only gentle to moderate northwest and north breezes. The Labrador 

 coast was sighted early on July 10. The last station of the section was 

 taken about 15 miles north of South Wolf Island at 10 a. m. Then 

 we started a line of stations from this point to Cape Farewell on the 

 southern point of Greenland. When near the coast we sighted only 

 three icebergs, although the visibility was excellent. The eastern- 

 most berg was 40 miles from the coast. Abnormal refraction with 

 double horizons in all directions existed throughout the day of July 10. 



The weather continued fine until the morning of July 13, when a 

 moderate northeast gale was encountered when about 80 miles from 

 Cape Farewell. By noon the gale and sea had abated. The Green- 

 land coast was sighted at 2:45 p. m., 35 miles away. At this time 

 eight bergs and scattered pieces of pack ice were sighted to the north- 

 ward. At 7:40 p. m. we completed the last station of the section, with
