RESULTS OF DEPTH SOUNDINGS TAKEN FROM 
DRIFTING STATION A IN THE ARCTIC OCEAN 
DURING THE INTERNATIONAL GEOPHYSICAL 
YEAR, 1957-1958. 
(All soundings were made with sonic reflections from 
an explosive source, except where otherwise noted. Sounding 
positions are interpolated between astronomic fixes and 
accuracy varies probably from one to five tenths of a 
nautical mile in most cases. Depths have been corrected 
using Matthews "Tables of the velocity of sound in pure 
"water and sea water," London, 1939.) .
