 meridians 62 and 57, and south of this very little ice is seen. The 

 position of this field north and west of the most productive ber<T dis- 

 trict is an indication of the direction of drift of the glacial ice. 

 Since other parts of the bay at this particular time of the year 

 usually have fewer bergs, this group, therefore, in all probability

FiGUHE 9o. — The distribution of icebergs in Davis Strait as 

 observed by the Marion expedition the summer of 1928. 



Immediately north of Upernivik the current and bergs spread out 

 and the entire expanse of the surface waters from Upernivik to 

 Cape York, and offshore for a distance of 90 miles, partakes of a 

 slow movement toward the northwest, averaging about 5 miles per 

 day. The direction of the current is generally parallel to the coast 

 but its course is winding and, therefore, a berg arriving at Uper-
