Figure F1. Area of Leg 207 operations on the Demerara Rise, showing positions of seismic tracklines, DSDP Site 144, and industry exploration well site Demerara A2-1.
Figure F2. Seismic grid shot during survey Meteor 49-4 (solid lines) with industry multichannel tracklines (dashed lines) over the Demerara Rise, with proposed Leg 207 drill site locations (primary sites in bold).
Figure F3. Detailed bathymetry of Demerara Rise with positions of the proposed Leg 207 drill sites. Primary sites are indicated by larger (red) type. GeoB4013 is a gravity core taken during the Meteor 49-4 expedition.
Figure F4. Global paleogeographic reconstruction of the Late Cretaceous showing the position of the Demerara Rise in the early South Atlantic.
Figure F5. Seismic stratigraphy of MCS line GeoB01-220 at the location of DSDP Site 144 and proposed Site DR-8B. See text for details of seismic stratigraphic intepretation. Stratigraphy and core recovery at Site 144 is also shown. CDP = common depth point.
Figure F6. Scanning electron micoscropy photos of planktonic foraminifers from late Cenomanian black shales of DSDP 144. Note the perfect preservation.
Figure F7. Stable isotope data from DSDP 144-4, 144-3, and 144-2, showing small but consistent interspecies offsets. This observation demonstrates the potential to generate modern high-resolution records from the Demerara Rise cores.
Figure F8. Mid-Cretaceous oceanic anoxic events (OAE) and patterns of faunal turnover. Shown also are secular changes in seawater strontium and carbon isotope composition and estimated ages for oceanic plateoa emplacement (from Leckie et al., in press).
Figure F9. Global deep-sea isotopic record compiled from numerous DSDP and ODP sites (Huber et al., 1999; Norris et al., 2001; Zachos et al., 2001). LPTM = late Paleocene Thermal Maximum, CO = Climatic Optimum. Modified from Kroon et al. (2002).Next Section | Table of Contents
