Bathymetry, control positions and aspect of proposed SOFAR stations in the Pacific Ocean

Abstract

The purpose of this memorandum is to present the available information on the nature of the bottom off the coasts of California and Hawaii adjacent to the proposed SOFAR stations in the Pacific Ocean, the best probable location for the hydrophones, the probable areas of reception, the positions of fixed land control points, and other information that will facilitate the establishment of an efficient monitoring system. The writer is indebted to the Director and personnel of the U. S. Coast and Geodetic Survey for copies of boat sheets containing soundings, data on the deflection of the vertical, and triangulation station data in the areas involved.
