THIRD CRUISE, "MENDOTA", APRIL 10 TO APRIL 21, 1935 



The Mendota sailed from Halifax, Nova Scotia, at 0600, April 7, 

 and proceeded to the relieving point at economical speed, 121^ knots. 

 The run from Halifax was uneventful. The weather was generally 

 cool with good visibility and moderate westerly wind and sea. 



The Mendota contacted the Pontchartraiii in latitude 43°06' N., 

 longitude 52°00' W. At 0012, April 9, Lt. G. Van A. Graves, ice 

 observer, and the observer's party reported aboard, and at 0050 the 

 Mendota relieved the Pont chart rain as Ice Patrol vessel. Course was 

 set across the Grand Banks for latitude 44 ''OO', longitude 49°00', to 

 begin a search for ice to northward of the Pontchartrain's search on 

 6th and 7th of April. At 0909, the Mendota spoke to the French 

 Barkentine Saint Siiliac of Saint Malo. Three members of the crew 

 came aboard to verify their ship's position and to send radio messages 

 to France, reporting their safe arrival at the Grand Banks. The 

 Mendota intercepted an S. O. S. from the S. S. Toiverhridge in lati- 

 tude 47°20' N., longitude 47°23' W., at 0939. The Mendota proceeded 

 immediately on course 25° true at 15 knots to her assistance. At 1104 

 the S. S. Toicerhiidge reported the S. S. Newfoundhmd standing by 

 and no other assistance needed, so the Mendota headed east for the 

 eastern slope of the Grand Banks, arriving there at 1303. During 

 the remainder of the day the Mendota crtiised northeastward along 

 the 100-fathom curve. Xo ice was sighted. At 1815 slowed to one- 

 third speed and continued north during the night in case the- S. S. 

 Towerhridge needed further assistance. 



At daybreak, April 10. the Mendota commenced scouting to the 

 north and east between the 100- and 1,000-fathom curve. At 1023, 

 located a large berg in latitude 46°04' N., longitude 47^36' W. This 

 berg was over 500 feet long, 300 feet wide, and 100 feet high, and was 

 in the cold current in excellent position for drifting southward to 

 the tail of the Grand Banks. The water temperature was 30° F., 

 and 400 fathoms deep. The Mendota continued scouting northeast 

 and at 1050 sighted a large ice field. The remainder of the day was 

 spent skirting this ice field to the southward and eastward to deter- 

 mine its extent. During the day about 25 icebergs and many growl- 

 ers were sighted along the western edge of the field ice. The ice field 

 itself was 50 miles long, extending in a southeasterly direction and 

 probably 15 to 20 miles wide, containing many large and dangerous
