SECOND CRUISE, "TAHOE," MARCH 9 TO 22, 1938 



The Tahoe departed from Halifax, Nova Scotia, at 1700, March 9, 

 1938, on an ice observation cruise. Course was set from the sea buoy 

 to pass about 40 miles north of Sable Island in order to investigate 

 ice conditions there. Light local pancrke ice was encountered during 

 the night and the next day with a few scattered larger pieces but no 

 hindrance or danger to navigation. There was, however, evidence 

 of more and heavier ice to the northward and shipping would do well 

 to continue south of Sable Island for a few more weeks. The next 

 day the Tahoe scouted south of Cape Race along latitude 45°30' N., 

 between east and west bound track E and sighted large patches of 

 broken field ice in latitude 45°30' N., longitude 52°33' W. That 

 afternoon and the morning of the next day, IVIarch 12, gales and high 

 seas prevented all scouting so the Tahoe made the best way she could 

 toward the eastern slope of the Banks so as to be ready to commence 

 a search for ice when the weather moderated. 



The morning of March 13 was fine and clear with moderate north- 

 west winds and the search was planned so as to scout the cold current 

 northward from latitude 45° N., just outside the 100-fathom curve. 

 Field ice was encountered in latitude 45°38' N., longitude 47°54' W. 

 The remainder of that day and the next was spent skirting this ice to 

 the northward along its eastern edge to latitude 47°50' N., longitude 

 48°00' W., or approximately 200 miles along the 100-fatliom curve. 

 This ice was heavy and contained numerous dangerous pieces of 

 arctic pack ice and numerous growlers and completely blocked Cana- 

 dian tracks E and F. Two small bergs and two large growlers were 

 located in the field in approximate latitude 46°14' N., longitude 47°35' 

 W. On March 15 and 16 the Tahoe ran back southward along this 

 same ice and found that the westerly gales on the 15th and the 

 morning of the 16th had driven the ice eastward into warmer water 

 and scattered it so that all but the larger pieces had melted. The 

 bergs sighted on the 13th were relocated on the 16th in vicinity lati- 

 tude 45°15' N., longitude 48°00' W.
