Middle Atlantic Bight Field Study: SUS Component

Abstract

Our long term objective is to investigate the feasibility of using broadband explosive sources such as SUS charges for inversion of oceanographic fields and sediment parameters. We have performed nonlinear inversions using a combination of global search methods (Genetic Algorithm) and local least squares optimization schemes (Levenberg - Marquardt). The inverted oceanographic fields are coefficients of empirical orthogonal functions of the sound speed field in the water column, sediment compressional wave speeds at various depths, bathymetry and source-receiver range. The ocean sound speeds and bathymetry are assumed range dependent while sediment is assumed range independent. We are also estimating the spatial resolution and error properties of the inverted fields and parameters.
