PREFACE 



The early history of oceanography is inseparable from that of discovery and exploration, 

 which in turn depended upon a thirst for knowledge and the quest for trade. The sailors of old, 

 despite knowing little or nothing of what lay beyond and inadequately provided with ships and 

 gear, put to sea resolved to do their best to accomplish something of note and to bring back their 

 data and conclusions. 



Today we are confronted with challenges that need the sprit and imagination of yesterday's 

 adventurers. 



Through tales of ships and deeds, Mr. Nelson's treatise illustrates the long and mutually 

 beneficial association of the Navy with science and industry, with fisherman, and with the mer- 

 chant marine in the broad field known as oceanography. It is by this continuing spirit of coopera- 

 tion that we will ensure that our country maintains its leadership in the effective use of the sea and 

 fulfills its obligation to mankind.
