GEOTECHNICAL AND ACOUSTIC CHARACTERISTICS OF PLIOPLEISTOCENE SEDIMENTS FROM THE HEBRIDES SLOPE

Geotechnical data from Plio-Pleistocene sediments on the Hebrides Slop e provide the basis for an analysis of potential factors controlling t heir acoustic character as observed on high-resolution seismic reflect ion profiles. Differences in acoustic signature within the sedimentary succession are related to the void index and thus to soil structure a nd, in turn, to the depositional history of the sediments. In this exa mple, a correlation can be demonstrated between the seismic and geotec hnical stratigraphies.
