Data from "Sound Reflection from the Sea Floor and its Geological Significance" by Lloyd R. Breslau (NCEI Accession 7001147)
Listed in NASA Earthdata CMR
The objective of this investigation was to measure bottom loss in normal incident reflection of pulses of 12 kcps sound and to study its geological significance.
Description
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.
