PUBLISHER'S STATEMENT 



Reference texts devoted entirely to the concepts of 

 arctic ice and arctic oceanograpiiy have not previously 

 been available in English. While the bibliography of 

 technical papers covering many specific properties of 

 sea ice and the oceanography of the Arctic Ocean has 

 expanded considerably in the past few years, N. N„ 

 Zubov's classical reference, "Arctic Ice, "still holds 

 much historical interest and provides general infor- 

 mation of significant value to the beginning 

 investigator. 



During the past ten to twelve years portions of this 

 text have been translated and abstracted at the request 

 of various investigators reviewing the literature and the 

 status of arctic problems. Because of the increasing 

 interest and number of requests for translated portions 

 of the book a cooperative project was established to pro- 

 bi ^SCi vide a complete bound translation. The present transla- 



tion was accomplished by the L). S. Navy Oceanographic 

 Office and the American Meteorological Society under 

 contract to the U. S. Air Force Cambridge Research 

 Center. Final technical editing and publishing was by 

 the U. S. Navy Electronics Laboratory.
