Bottom Loss Upgrade (BLUG) Extensions to Strategic Shallow Water Areas: Korea Strait.

Abstract

BLUG is a worldwide Northern Hemisphere database of the acoustic properties of ocean bottom sediments. Using nine parameter it characterizes sound speed and attenuation profiles and sediment and basement interface reflectivity. This information is sufficient to calculate the acoustic propagation characteristics of bottom interacting acoustic signals for arbitrary source-receiver geometries. This report documents an effort to apply BLUG methodology to the shallow water acoustic propagation environment in the Korea Strait. There exists a large collection of geological data for the area, so that the original deep ocean database. However, the large number of distinct identifiable geoacoustic areas in the Strait reflects the actual complexity of an environment with strong tectonic and oceanographic effects. Development of the geoacoustic areas was based on quantitative measures of grain size and sediment thickness, as well as qualitative estimates of the roughness of the sediment surface and the underlying basement rock. Keywords: Bottom loss; Roughness.
