FOREWORD 



Oceanography, the application of the sciences to the study of the oceans, has been the 

 subject of considerable worldwide attention during the past few years. The reason behind its 

 popularity is, of course, the almost universal acceptance of the sea's role in the future of man- 

 kind. In an address presented on July 13,1966, President Lyndon B. Johnson took note of the 

 importance of this role. He portrayed our newly awakened scientific interest in the sea as 

 "a new age of exploration" and described the high adventure that still awaits those pioneers 

 who enter upon "our last frontier on earth". Addressing himself in particular to a group of 

 youthful guests consisting of outstanding high school students, the President stated, "I hope 

 that there are among you some of the great oceanographers of tomorrow. You could not 

 choose, in my judgment, a more important or a more challenging career". 



Science and the Sea, a compilation of ten articles describing some of the practical aspects 

 of the marine sciences, is presented to acquaint both teacher and student with a few of the 

 realistic problems that face the modern oceanographer. The articles were selected on the basis 

 of applicability from a series of original papers specially prepared for presentation on the re- 

 verse sides of the Pilot Chart of the North Atlantic Ocean and the Pilot Chart of the North 

 Pacific Ocean. These charts are published monthly by the U. S. Naval Oceanographic Office 

 to provide mariners with a graphic synopsis of meteorological and oceanographic conditions 

 prevailing in the waters specified.
