Figure 1. 3D seismic data from the Gulf of Mexico, showing two high amplitude frontal splay erosional remnants within a slope master channel complex. A) Spatial extent of the erosional remnants and the four incised channel threads, listed from youngest to oldest. A transparent plane indicates the position of Inline 4915. B) Inline 4915, showing the topographic relief, high amplitude nature of the erosional remnants within the master channel complex.
