Data from "Sound Reflection from the Sea Floor and its Geological Significance" by Lloyd R. Breslau (NCEI Accession 7001147)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 06:07 AM | Dataset Last Updated: July 21, 2023 at 12:00 AM
This archival information package contains no digital representation of data from this publication. The publication can be obtain from the Massachusetts Institute of Technology at http://hdl.handle.net/1721.1/58011. 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. 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.
