Summary
Description
The objective of this investigation was to measure bottom loss in normal incident reflection of pluses of twelve keps sound and to study its geological significance. To this end a semi-automatic instrument system was developed which is capable of making continuous measurements of the peak pressure and the time integral of the square of the pressure of the sea-floor echo, from a vessel underway.
