Seismic profile Line 12 (Airgun). TWT: two-way travel time. Vertical line represents location of cross lines. (a) Uninterpreted image (post-stack, vertical exaggeration = 20). White triangle: representative seafloor multiple. Note the presence of high-amplitude negative polarity reflector at shallow depths (CMP #120–180). (b) Trace of seismic reflectors in (a) and interpreted image. The seismic units at deeper sections (light to dark pink) are assigned at the base of representative seismic reflectors traceable with other sections
