Abstract
Echo sounding records were used to identify roughness features in the wavelength ranges 6 km to 12 km, 2 km to 6 km, 0.6 km and 3 km, and less than 1 km. The latter features are not resolved at 3.5 km ocean depths. The character of the echo sounding trace was used to find the location of microtopography or small features. Within each of the spectrum regions, the rms roughness has been estimated. We found some long wavelength features having small roughness and others that were smooth. Acoustic implications will be discussed. The area studied in detail is 32°N to 40°N and 9°W to 16°W. Marine Geophysical Survey (1965–66), Naval Oceanographic Office, and Lamont-Doherty Geological Observatory data were used.
