EIGHTH CRUISE, "PONTCHARTRAIN", JUNE 19 TO JULY 2, 1935 



The Po)ht char train sailed from Halifax, Nova Scotia, at 0()40, June 

 16, 1935, for patrol. The run from Halifax to the relieving point 

 was uneventful. Light winds and calm sea with good visibility were 

 experienced until the tail of the Banks was reached when fog and 

 low visibility were encountered. 



The Pontchartrain met the Mendota in latitude 43°32' N., longi- 

 tude 49°03' W. Lt. G. Van A, Graves, ice observation officer, and the 

 observer's party reported aboard and at 1245, June 18, the Pont- 

 chartrain relieved the Mendota as Ice Patrol vessel. Course 110° true 

 was set and the Pontchartrain commenced scouting up the axis of 

 the cold current with visibility about 5 miles. Dense fog set in at 

 1600, and intermittent fog prevented all further scouting, so at 2120 

 the Pontchartraiyi anchored in 35 fathoms of water in latitude 44°34' 

 N., longitude 49° 06' W., to maintain position for the night. 



The weather cleared in the early morning hours of June 19, and 

 at 0430 the Pontchartrain commenced an intensive scouting plan of 

 the critical area in the southward moving water along the eastern 

 edge of the Grand Banks from latitude 44° 30 N. to latitude 46°50' 

 N. The next day, June 20, the search plan was completed as far 

 south at latitude 43°45' N. (See fig. 17.) The ice sighted in 

 this area was two growlers in latitude 45°57' N., longitude 48°32' W., 

 und one medium berg in latitude 45°05' N., longitude 48°43' W., 

 both on June 19. The berg was relocated on June 20 in latitude 

 44°23' N., longitude 48°58' W. As this berg was the southernmost 

 known ice, the PontchaTtrain at 1818 returned to stand by this berg 

 for the night in latitude 44°19' N., longitude 48°58' W. The Pont- 

 chartrain drifted with this berg throughout the next day and night 

 as it moved rapidly southward with the cold current. During the 

 night of June 20 the berg was lost in dense fog which persisted over 

 the area until 0526, June 23, when the berg was relocated in latitude 

 43° 18' N., longitude 49° 11' W. Dense fog set in at 1640, and the 

 Pontchartram. drifted in the vicinity of the berg the rest of the day 

 and throughout the night. 



The next 2 days, June 24 and 25, dense fog prevailed and no con- 

 tact could be maintained with the southernmost berg. On June 26, 

 with 2 hours clear weather in the morning, and 4 hours intermittent
