NINTH CRUISE, "CHELAN," JULY 13-26, 1939 



The Chelan sailed from Halifax, Nova Scotia, at 1811, on July 10, 

 1939, to relieve the Champlain on Ice Patrol duty. Southerly breezes 

 with dense fog were experienced on the run to the relieving point. 

 The Champlain was met in latitude 44°20' N., longitude 52°43' W. 

 The ice observation party reported on board and at 1135, July 13, 

 1939, the CAe/a« relieved the Champlain as Ice Patrol vessel. Dense 

 fog persisted from the 13th to 21st, inclusive, so the patrol vessel, 

 believing the bergs sighted by the Champlain on the 1 1th would remain 

 nearby, maintained position in vicinity of latitude 4o°00' N., longitude 

 49°00' W. During a brief clearing on July 20, a berg sighted by the 

 Champlain on the 11th in latitude 44°45' N., longitude 49°07' W. was 

 found in latitude 44°50' N., longitude 49°05' W. 



With excellent visibility from July 22 to 25, the waters of the entire 

 Labrador Current south of latitude 45°00' N., were thorouglily searched. 

 The berg sighted on July 20 was relocated on the 22d in latitude 

 44°55' N., longitude 48°59' W.; on the 23d in latitude 44°38' N., 

 longitude 48°52' W.; and on the 24th in latitude 44°28' N., longitude 

 48°50' W. \Vlien left on the latter date it had been reduced to a 

 growler. It Avas reported as late as- July 25 as a small berg, but 

 probably was completely disintegrated in the storm and swell of the 

 26th. On July 25 a large berg was sighted in latitude 44°38' N., 

 longitude 48°14' W. This berg was the same as one sighted by the 

 Champlain on July 11 in latitude 44°27' N., longitude 48°3S' W. and 

 when first sighted on the 25th it was 31 miles distant from the patrol 

 vessel. On the afternoon of July 25, with good visibility, the patrol 

 vessel scouted north to latitude 46°19' N., longitude 47°36' W. in an 

 effort to relocate bergs reported along tliis track on the 22d and 24th. 

 No ice was found and during the night course was set to the south- 

 ward. The berg sighted on the 25th was relocated on the morning 

 of the 26th in latitude 44°47' N., longitude 48°10' W., having drifted 

 north by east into an easterly wind approximately 11 miles.
