Chesapeake Times, Vol 2 | July 2020 The interpretation of marine seismic profiles is complicated by the fact that operators must separate useful information about subsurface geometry from a wealth of background interference and noise typical of marine surveying. One of these problems is the presence of multiple reflections or reverberations. These slowly decaying wave trains usually arise in the water layer, which tends to trap the sound wave bouncing back and forth between the seabed and the sea surface. The most prominent of these multiples and usually the first to arrive are harmonics associated with the seafloor reflection. Take for example the …
