SPECTRAL STUDIES OF MARINE GEOPHYSICAL PROFILES

Abstract

Gravity, magnetic, and echo‐sounding data profiles from widely separated single‐track surveys in the Atlantic and Indian Oceans were subjected to spectral studies. A two‐dimensional sea floor with a recurring structural pattern seemed a model able to explain the computed results. In testing the model, the most important quantity to be determined from the spectra was the “ripple frequency” or interpeak interval. During the course of this work, a number of practical problems connected with the computation of spectra were considered. In addition, the spectral methods were also shown to be tools capable of investigating more complex geophysical theories. The experience and techniques of this investigation can be of value in treating analogous problems which arise in geophysical exploration.
