Development of Expendable Sounding Devices.

Abstract

Numerous devices have been developed for the reconnaissance of a beach approach prior to an amphibious landing. This report describes two methods for the determination of the underwater beach profile. One method employs a remote-controlled, self-propelled, recording fathometer; the other, a simple line-float device for dropping from aircraft.
