RESUME 



During this cruise 160 ice reports and 950 water temperature 

 reports were received from steamers and 17 ice reports from Cape 

 Race. Six derelict reports were received and broadcast. Warn- 

 ings of bergs on their courses were sent to 45 steamers following their 

 requests for information and additional information was furnished 

 to 7 other steamers. Eleven special ice broadcasts were sent out 

 in addition to the scheduled ones and 27 weather reports were trans- 

 mitted. 



WEATHER 



(See Charts Nos. 11, 12, and 16) 



Only one gale was experienced during this cruise. It made its 

 appearance very suddenly at noon of May 21 and lasted until the 

 evening of May 22. About 5 of the 15 days were favorable for 

 visibility and observations, the rest being foggy and rainy with low 

 visibility. The percentage of fog was 64.4 per cent. 



WATER TEMPERATURES 



(See Charts Nos. 11 and 12) 



Nine hundred and fifty water temperature reports were received 

 and plotted. The chart evidenced a continuation of the conditions 

 existing during the previous period. The cold water area decreased 

 in size until at the end of the period there was very little cold water 

 on the surface south of the forty-eighth parallel. A narrow tongue 

 of Arctic water still extended to latitude 46° 20' N., along the edge of 

 the Banks. Although the warmer water was pushed northward 

 along the Banks, there remained a subsurface tongue of Arctic water 

 down to latitude 45° 30' N. at depths of 25 and 50 meters. This 

 apparently accounted for the drift of a few bergs below latitude 

 46° 00' N. The weakness of the flow of the Arctic current was 

 reflected in the movements of the bergs during that period. Al- 

 though a comparatively large number of bergs were reported around 

 the northeast slope, their southerly drift was very slow and onl 

 bergs were encountered south of latitude 46° 00' N. 



ICE 



(See Chart No. 5) 



One hundred and sixty berg reports were received fro 

 and 17 reports from Cape Race during this cruise. Th 

 stood by the largest berg, which also proved to be the southerrP 

 ice, a great deal of the time in order to obtain accurate data in regard 

 to its drift. This berg was originally No. 7 of the first group seen
