| Abstract | Geoacoustic models of the seafloor are essential components of underwater and seafloor acoustic studies. Propagation velocities for compressional and shear waves in the seafloor material are important geoacoustic parameters. Previously reported values for shear wave velocities in seafloor carbonate oozes have shown wide disparity. New laboratory measurements of compressional and shear wave geoacoustic parameters have been made as a function of effective stress. Periplatform carbonate samples from the Little Bahama Bank and Exuma Sound in the western North Atlantic Ocean were used for these measurements. Conventional pulse timing compressional wave velocities were measured. Shear wave parameter measurements were made with a new technique using duomorph sensors embedded in the seafloor sample. The resulting compressional wave velocity values are consistent with previously reported measurements for similar material (e.g. Hamilton). The shear wave dynamic property values obtained are more consistent with the lower shear wave velocity values reported, for example by Schultheiss. These lower shear wave velocities also agree with values obtained by pulse timing measurements with bender bimorph transducers in samples from the same seafloor region. |
