The Gulf of Mexico experiment involved a broadband source (100-600 Hz) transmitting pseudo-random noise. The acoustic field was received by five hydrophones positioned vertically in the water column. By performing a correlation between the received time series and the transmitted signal, an approximation of the impulse response for the ocean channel is obtained. This impulse response is readily interpretable to yield information about the experiment, especially its geometry including receiver and bottom depths. With this refined environmental information, we then apply matched-field processing to obtain the source position.
