Abstract:

The contractor analyzed available horizontal and vertical array data acquired during Overbid Leo Leg 4 to estimate angle and time spreads versus grazing angle and number of bounces of bottom-bounce signals in thin-sediment areas. Comparisons with existing theories were made to evaluate their ability to model these phenomena using independent environmental data. This final report briefly summarizes results of two contract reports Angle, Time and Frequency Spreads from a Thin-Sediment Area of the Northeast Pacific Ocean and Shallow Sub-bottom Reflectors in the N.E. Pacific--Distribution and Physical properties.
