Broadband Seismic Data used for Seafloor Sediment Classification

The echo returns from a broadband deep towed seismic system are examined. It is shown to be possible to separate four different sediment types based on two metrics. These are i) the maximum value of the normalized cross-correlation function and ii) the normalized water-sediment interface energy. For the small data base used these two metrics give complete separation of the four sediment types.
