FOREWORD 



The activities of the International Ice Patrol for the 1951 season 

 are presented herein. This bulletin adheres to the same general 

 pattern established in previous years except that the "Table of 

 Ice Reports" returns to the former practice of listing all ice 

 reports chronologically without regard to whether the particular 

 report was north or south of any particular latitude. Similarly, 

 the monthly digest of ice conditions incorporates all significant ice 

 information in all latitudes. Obstructions other than ice, such as 

 drifting buoys, derelicts, etc., have not been included in the "Table 

 of Ice Reports" since their significance therein is doubtful. 



The oceanographic section was prepared by Oceanographer 

 Floyd M. Soule, Lt. P. S. Branson and Lt. (jg) R. P. Dinsmore. 

 Lt. ( jg) Sam Pisicchio, U. S. C. G., prepared the sections pertaining 

 to the conduct of the International Ice Patrol.
