PREFACE 



This bulletin is the annual report of the International Ice Patrol 

 Service for 1962. Annual reports have been published since 1913 

 with the exception of the war years. This bulletin is divided into two 

 parts. The first is a report of the patrol operations which extended 

 from 6 March to 22 June 1962. Aircraft and communication activities 

 are described and special sections deal with observed monthly ice 

 conditions and statistics on ice and sea temperature reports for 1962. 



The second part deals with physical oceanography in the Grand 

 Banks region and the Labrador Sea. Included are charts of dynamic 

 topography of the sea surface demonstrating the ocean current, tables 

 of oceanographic data and a brief discussion of the results of the 

 season's four oceanographic surveys and the special postseason re- 

 search cruise in the Labrador Sea, Davis Strait and Baffin Bay. 



The authors of the section on oceanography are Floj'd M. Soule, 

 Oceanographer, U.S.C.G., Alfred P. Franceschetti, Oceanographer, 

 U.S.C.G., Lieut. V. W. Driggers, U.S.C.G., and Lieut. R. M. O'Hagan, 

 U.S.C.G.R., except that that part dealing with the nutrients found 

 during the postseason cruise is the work of Nathaniel Corwin and 

 David A. McGill, both of the Woods Hole Oceanographic Institution. 

 The remainder was written by Capt. R. P. Bullard, L^.S.C.G., and Lt. 

 Comdr. R. E. Lenczvk, U.S.C.G.
