OCEANOGRAPHIC SUMMARY. 



Lieut. Edward H. Smith, U. S. Coast Guard. 



We are now prepared to sum up the history of oceanographic events 

 for the ice season of 1923 in the vicinity of the Grand Bank, based 

 upon profiles 1-15. In general. 1922 was considered a normal year 

 and 1923, in most respects, corresponded, especially as regards num- 

 ber of bergs. 



It was noticed b}^ the ice-patrol vessel on her initial appearance in 

 the region of the Grand Bank, March 13, that the majority of bergs 



were following courses which carried them offshore and that scarcely 

 any were taking the path which had come to be regarded as normal, 

 southward along the eastern continental edge of the Grand Bank. 

 Such berg drift being unusual, an examination was made which gives 

 a picture of oceanographic conditions prevaihng below the surface at 

 that time and place, the results of which can best be illustrated by 

 a sketch of the horizontal plane at the 100-meter (55-fathom) depth.
