fms, or 37 m, in ali 3.5 kHz records) reproduced at the same horizontal scale showing slope
transect from Pantelleria Trough to Adventure Bank. Near-horizontal Pliocene and Quaternary
(P-Q) sediment of the basin distinct in both records is shown abutting against the base of the
slope, which appears relatively free of sediment cover. (Some of the normal faults are indicated
by the dashed lines. Depth in seconds, two-way travel time.)
