FIGURE CAPTIONS

Figure F1. Overview map of Walvis Ridge. The boxes indicate locations of more detailed maps to follow.

Figure F2. Area of Leg 208 operations on Walvis Ridge. Meteor track lines cross existing DSDP Leg 74 and proposed ODP Leg 208 sites.

Figure F3. Area of Leg 208 operations on central Walvis Ridge. Open circles = proposed primary and alternate sites.

Figure F4. The location of Leg 74 sites along Meteor line GeoB01-030.

Figure F5. Lithostratigraphy of DSDP Leg 74 Sites 528 and 529 (Moore, Rabinowitz, et al., 1984). White gaps = unrecovered intervals.

Figure F6. Low-resolution bulk sediment carbon isotope stratigraphies for the Leg 74 sites (Shackleton and Hall, 1984).

Figure F7. Cenozoic deep-sea stable isotope record based on a compilation of benthic foraminifer data from several dozen pelagic cores (modified from Zachos et al., 2001). The oxygen isotope record primarily reflects on changes in deepwater temperature and ice volume.

Figure F8. Benthic foraminifer isotope records of the Paleocene–Eocene Thermal Maximum (PETM) (Zachos et al., 2001).

Figure F9. Box model simulated response of the ocean C-isotopes and lysocline to gradual (10 k.y.) input of 1200 gigatons of methane-derived carbon into the ocean (Dickens, 2000).

Figure F10. DSDP Site 527 planktic foraminiferal stable isotope records plotted against depth for the three size fractions of Acarinina soldadoensis (90–150, 150–250, and 300–355 dicates the position of the claystone interval within Core 24. The CaCO3 record reveals a low carbonate layer coincident with the PETM (Thomas et al., 1999).

Figure F11. A composite of the Cibicidoides spp. stable carbon and oxygen isotope records for Sites 522, 744, and 689 plotted as a function of age for the period 31–35 Ma (Zachos et al., 1996; Diester-Haas and Zahn, 1996). The EOGM spans the interval 33.0–33.4 Ma. Age model is based on the geomagnetic polarity timescale of Cande and Kent (1992). Lower scale shows bottom-water temperature for an ice-free world (pre-EOGM) assuming calcite formation in oxygen isotope equilibrium (Zachos et al., 1996).

Figure F12. DSDP Site 525 on multichannel seismic line GeoB01-031 and DSDP Site 528 stratigraphic column (from Moore, Rabinowitz, et al., 1984).

Figure F13. DSDP Site 525 and proposed Sites WALV-8A, WALV-8B and WALV-8C on multichannel seismic line GeoB01-031.

Figure F14. Common depth point–annotated track chart around proposed Sites WALV-8, WALV-9, and WALV-10 (shown as open circles). Solid circles = existing DSDP sites. Bold lines = profiles included into the data package.

Figure F15. Common depth point–annotated track chart around proposed sites WALV-11A, WALV-11B, WALV-11C, and WALV-11D (shown as open circles). Solid circles = existing DSDP sites. Bold lines = profiles included into the data package.

Figure F16. Common depth point–annotated track chart around proposed sites WALV-12A, WALV-12B, and WALV-12C (shown as open circles). Bold lines = profiles included into the data package.
