THE INFLUENCE OF A LOW VELOCITY LAYER ON THE REFLECTIVITY FROM THE SEA FLOOR.

Abstract

The influence on the reflectivity of a low velocity layer on top of a sand half-space has been investigated. By expressing sediment density and velocity in terms of porosity it has been possible to use this quantity as an independent variable. To characterize the reflectivity, both the reflection loss in decibels and the distortion after reflection of two broad band pulses have been used. The calculations were carried out on a digital computer and the results are presented in the form of curves and graphs. (Author)
