Abstract : This report formulates an experimental computer program for seamount model parameter estimation. The computer algorithm documented was designed to automatically recognize those characteristic perturbations among satellite radar altimetry data that indicate the presence of seamounts. Featured are a digital filter, a roughness detector, a physical model containing the potential theory associated with seamounts and specifying their effect on the sea surface and, finally, the estimator algorithm for the model parameters, in particular peak submergence depth. Also included are an error analysis and computer program checkout data. (Author)
