Figure 1. Location of the two general areas to be drilled during Leg 166. Location of cores Unda and Clino drilled during the BDP (Bahamas Drilling Project) also are shown. Sites BT-1 through BT-4, F-3 and BT-20 are located in the upper large box. Sites F-4 through F-6 are located in the lower box. Boxes correspond to areas represented on Figs. 6 and 8.
Figure 2. Schematic cross-section showing the Bahamas Transect. The two proximal sites, Unda and Clino, were drilled during the Bahamas Drilling Project. BT-1 through BT-4 are planned to be drilled during Leg 166.
Figure 3. Line drawing of the prograding sequences at the western margin of the GBB with drilling locations of Unda and Clino. Sequences h-a are late Miocene to Holocene in age. Miocene/Pliocene boundary is on top of sequence f. Sequence boundaries are indicated by truncations (sequences h, g, f) and/or onlap patterns (sequences e-a). Stippled areas are onlapping packages; white areas are prograding downlapping units.
Figure 4. Correlation of ages, sedimentary successions, seismic reflectors and sequences, and gamma-ray signature of Clino and Unda.
Figure 5. Generalized correlation between Unda and Clino using the integrated age model. Seismic sequence boundaries (shaded lines labeled with SB) appear to be conformable within the resolution of the time lines (from McNeil et al., in press).
Figure 6. Location of seismic lines and drill sites of the Bahamas Transect (see Fig. 1). BT-1 through BT-4, BT-20, and F-3 are primary sites. BT-1 through BT-4 are positioned on the same seismic line as Unda and Clino; BT-20 is intended to assess lateral variability. F-3 is a site with fluid-flow objectives.

Figure 8. Location of seismic lines at the southern area (see Fig. 1). F-6 through F-4 are the locations of the fluid flow transect.
Figure 9. Seismic line showing the drill sites of the Bahamas Transect (BT-1 through BT-4) and the sites of the fluid-flow objectives (BT-1, F-2, F-3, BT-2), and intended depths of penetration.
