Preface 



Findings presented in this paper are based upon field observations collected as part 

 of the Coast and Geodetic Survey's oceanographic survey program of the central North 

 Pacific Ocean. The paper was prepared originally as a thesis in partial fulfillment of the 

 requirements for the degree of Master of Science in oceanography at the University of 

 Washington, Seattle, Wash., in 1964. As a thesis, the paper was titled "Deep Circulation 

 in a Portion of the North Pacific Ocean During the Summers of 1961, 1962, and 1963." 

 The author, who participated in the North Pacific Ocean survey during 1961, 1962, and 

 1963, is grateful for the opportunity afforded him by the Coast and Geodetic Survey 

 to pursue graduate study in oceanography at the University of Washington. He would 

 like to acknowledge the interest and support shown by the faculty and staff of the Depart- 

 ment of Oceanography at the university during preparation of the thesis — particularly 

 Dr. Clifford A. Barnes for helpful guidance, Dr. Maurice Rattray, Jr., for critical review, 

 Mrs. Monique Rona for machine processing of data, and Mr. Donald R. Doyle for prepara- 

 tion of illustrations. Machine processing of data and preparation of drawings were 

 supported in part by the U.S. Office of Naval Research (Contract Nonr 477-10, Project 

 NR 083012). The paper is published in its original form except for editorial revision of 

 format. Illustrations are grouped at the end of the paper. The list of symbols is in 

 appendix III.
