Figure F3. Line GeoB 01-030 with the locations of Site 1266 and DSDP Site 528 (proposed Site WALV-10A) and age estimates of prominent reflectors. A middle–upper Miocene reflector (RM1) is estimated to be at 105 mbsf, the Oligocene/Miocene boundary reflector (RO/M,) is estimated to be at 140 mbsf, the Paleocene/Eocene boundary reflector (RP/E) is estimated to be at 275 mbsf, and the Cretaceous/Paleogene boundary (RK/P) is estimated to be at 350 mbsf. All reflectors can be identified over most of the surveyed area. CDP = common depth point.
