Five major reflectors in multichannel seismic common-depth-point line 667 (acquired with an airgun source), single-channel seismic ODP line 5 (acquired with a high-resolution watergun), and expanded spread profile C2 can be dated and tied to lithologic units with results obtained during drilling of Site 763. Through an initial r-sum construction, followed by traveltime and full waveform forward modeling, ESP-derived compressional wave velocities can more accurately match traveltimes of these reflectors than full-reflectivity synthetic seismograms produced from shipboard-derived properties. Instrument calibration, drilling disturbance, and rebound effects suffered by the laboratory samples are sources of error. We speculate, based on the physical properties of the units that reflector " b " (—2 s TWT) marks a decrease in the degree of induration of upper Oligocene chalk. Reflector " c " marks the Cretaceous/Tertiary unconformity; " e " (—2.25 s) marks the abrupt disappearance of the terrigenous component of the sediments at the Cenomanian/Turonian boundary in response to the disappearance of the clastic supply; "f' (—2.4 s) is found above a breakup unconformity; and "g" (—3.15 s) arises near the top of the Triassic pre-rift basement in a thin (50 m) high-velocity (4 km/s) region of shallow-water reefal limestones.
