Abstract : This is a final report for the project, The Application of Inverse Methods to the Ocean Environment, supported by the Selected Opportunities Research Program of the Office of Naval Research at the Colorado School of Mines. During the three years spanned by the SRO, we have made major progress in the theory and application of inversion methods. At the start of the SRO, our inversion techniques were restricted to idealized data and physical assumptions. At the conclusion of the SRO, the theory and techniques had been extended to encompass most of the standard data collection procedures and were based on much more realistic physical assumptions. Our research efforts have been reported in technical reports, journal articles and proceedings and have been presented at national and international meetings including invited talks and invited articles. The SRO program at the Colorado School of Mines consisted of two major projects in inverse scattering. The first of these is reflector imaging for seabed mapping and seismic exploration. The second is ocean profile inversion. The progress achieved in both of these projects under the support of this contract is described in this report. The work continues. Keywords: Approximation(Mathematics); Ray tracing; Shear speed; Sound speed.
