Abstract
AREAS OF THE OCEAN FLOOR DISPOSED TO MINE BURIAL HAVE SOFT SEDIMENTS (I.E., LOW SHEAR STRENGTH) OR SANDY SEDIMENTS SUBJECT TO SCOUR. KNOWLEDGE OF SEAFLOOR SHEAR STRENGTH, POROSITY, AND GRAIN SIZE WOULD AID THE HUNT FOR BURIED MINES. NORMAL INCIDENCE, ACOUSTIC ECHO SOUNDERS ARE BEING DEVELOPED TO INFER SUCH PHYSICAL PROPERTIES OF THE SEDIMENT. PSI PROPOES TO EVALUATE THE THE POTENTIAL FOR SUCCESS OF THESE SYSTEMS THROUGH THE USE OF A THEORETICAL PHYSICAL SEDIMENT MODEL. PSI WILL SHOW THE SENSITIVITY OF THE REFLECTION COEFFICIENT TO PHYSICAL PROPERTIES IN REALISTIC SEDIMENTS FOR SANDS, SILTS, AND CLAYS EACH TIED TO CORE OBSERVATIONS. WAYS OF DISCRIMINATING BETWEEN THE PHYSICAL CAUSES WILL BE INVESTIGATED.
