Head Waves in Asian Marginal Seas

Abstract

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].
