Normal Incidence Bottom Reflection Measurements in Atlantic Area C1.

Abstract

Normal incidence 12-kc reflection loss measurements indicate that this area may be one of variable reflectivity. Low loss values of 14 db show relatively good reflectivity, whereas high values of 24 and 26 db indicate poor reflectivity. The range of the Brass II losses coupled with the normal incidence measurements possibly indicates the variable sediment conditions that may be encountered in abyssal plain regions or in areas accessible to turbidity currents. A layered model may be used to explain theoretical fluctuations in reflection loss as functions of layer thickness and variations in sediment properties.
