(A) Seismic reflection profile obtained from SCS data. (B) Same as (A), but gray, blue, green, and orange lines highlight laterally continuous reflectors. (C) Two-dimensional Vp structure in two-way travel time. (D) Two-way travel time range corresponding only to unit-1. (E) 2-D Vp structure of unit-1 obtained by τ-sum inversion. In (B–E), the blue and green lines show the interface between unit-1 and unit-2 (Line A) and unit-2 and unit-3 (Line B), respectively. The orange line indicates a laterally continuous reflector from the seafloor multiple. In regions A and B in (C) and (D), two-way travel times of the continuous reflectors increase rapidly, and the layer with a Vp slower than 1.65 km/s thickens abruptly in two-way travel times. The vertical axis represents two-way travel time from the sea surface.
