Acoustic-gravity waves interacting with the shelf break

Kadri, Usama and Stiassnie, Michael 2012. Acoustic-gravity waves interacting with the shelf break. Journal of Geophysical Research: Oceans 117 , C03035. 10.1029/2011JC007674

A mathematical solution of the two-dimensional linear problem of an acoustic-gravity wave propagating over a bottom with a step, in a slightly compressible ocean, is presented. Expressions for the flow field on both sides of the step are derived. Furthermore, an extended problem is given that provides a solution for a group of acoustic-gravity waves, generated by a submarine earthquake, propagating toward a continental shelf. The dynamic bottom pressure produced by the acoustic-gravity waves is probably measurable, especially at the vicinity of the seaward face of the shelf break where incident and reflected modes appear simultaneously. A successful recording of such bottom pressures could assist in the early detection of tsunami.
