I. INTRODUCTION 



In June and July 1961, a continuous profile, marine 

 magnetic survey was conducted south of the Hawaiian Islands, 

 between latitudes 17°45' and 21°15' North, longitudes 158° 

 15' and 163°15' West. (See Index Chart, Figure 1.) This 

 survey was conducted by the USS REHOBOTH (AGS-50) as part 

 of the D. S. Naval Oceanographic Office* Project 0-162, 

 Equatorial Pacific Survey. The general purpose of the 

 survey was to collect data relevant to the physical, chemi- 

 cal, and biological aspects of the ocean environment in 

 this area. 



This report Is concerned primarily with the geomag- 

 netics phase of the survey. Bathjrmetric data are Included 

 to Illustrate certain points of correlation and interpretation. 

 The analyses and interpretation of data presented here are 

 limited to the identification and description of major 

 features. This has been done in order to make the survey 

 results available to other interested investigators at the 

 earliest date. 



*In accordance with Public Law 87-533 effective 10 July 1962, 

 the U. S. Navy Hydrographic Office was redesignated as the U. S,
