Abstract
Seismic pulses trapped between the ocean surface and the subbottom structure commonly observed in refraction profiling are modeled synthetically. The relative amplitudes of single‐ and double‐bounce phases are used to study reflection coefficients and attenuation. The technique was applied to a 1‐km‐thick section of mature oceanic sediments located in the Bering Sea. The most surprising result is the lack of attenuation in the sediments which is estimated to have a Qα greater than 500 for pulses dominated by 10‐Hz energy.
