Data collected during the Gulf of Mexico experiment were processed for the estimation of the source location and the bottom depth of the water column at the site of the experiment. The data consist of time series received at five vertically separated hydrophones after the transmission of a pulse in the 100- to 600-Hz frequency band. Successful estimation of the parameters of interest was achieved with simulated annealing. Using the calculated parameter estimates in simulations, a remarkable match was observed between real and synthetic data.
