| Abstract/Notes | The effect of seabed character on the distribution of acoustic energy reflected from the seabed was studied using digitized data from a high resolution, broad band, seismic source (Huntec Deep Towed Seismic System, Reflected energy was measured in two lime windows representing the lop metre of the seabed, and normalized to correct for operational variables and spreading losses due to propagation in the water column. These energy values were used to calculate acoustic reflectivity as a percentage of the energy content of the original outgoing pulse, and were displayed as continuous profiles alongside the seismic section. Most of the surficial geology formations on the Scotian Shelf, established from previous investigations, are seen to have a characteristic range in reflectivity. Thus, the acoustic reflectivity profiles enhance the seismic section by providing quantitative information on the nature and distribution of the lithology of the seabed in addition to the stratigraphic information which is normally obtained. |
