Figure F33. Seismic data and line-drawing interpretation of Sites U1322, U1323, and U1324. Ages in ka are estimated from biostratigraphy. Note the continuity of layers above Reflector S30 and below S80. Between these reflectors, the depositional system shows contrasts across the Ursa Canyon east levee deposits. The latter may have formed a high that partitioned deposition. LAD = last-appearance datum.
