The long-term goal is to develop a robust means to utilize readily-obtained precursor or head-wave-like arrival measurements for purposes of geoacoustic inversion. These arrivals are important features of shallow water propagation that are exhibited at relatively short ranges 1 km. They are more directly linked with seabed properties, in contrast to long-range, trapped modal arrivals. The objective this year was to analyze, model, and invert precursor arrivals measured from the Yellow Sea as part of the August 1996 joint U.S.-China Yellow Sea Experiment 1 using new methods derived the previous year of this grant 2.
