Figure F3. Seismic reflection profile I95-152 along a transect of the outer continental shelf through Lobe L1, with positions and penetration of drill sites marked and schematic projected position and penetration of Site 1097 (from between Lobe L3 and Lobe L4, where sequence group S1 topsets are much thinner). Shaded copy below shows seismic sequence groups S1, S2, S3, and S4. Modified from Barker, Camerlenghi, Acton, et al. (1999). TWT = two-way traveltime.
