Scattering from Marine Sediments in a Very Shallow Water Environment
Abstract
Abstract The goal of this research is to contribute to better understanding results of recentTarget and Reverberation Experiment, TREX2013. The experiment was performed in very shallow water (~20 m depth) with a complicated 3D variability of bottom properties and alternation of the sediment type (sand-mud-sand) along the propagation paths. The proposed research is to build on result of recent projects where several bottom interaction models and approaches relevant to such complicated environments were developed, which therefore can serve as a theoretical base for the TREX sea bed scattering data analysis. This research will refine developed models and codes taking into account specific conditions at the TREX site and result in model/data comparisons based on analysis of both TREX acoustic scattering data and environmental ground truth measurements, including most recent analysis of sediment samples and cores taken in the area during the experiment. The results will be presented in a paper prepared and submitted for a journal publication (JASA or JOE special issue on shallow water reverberation).
