Figure 1. East-west single-channel seismic reflection profile across Site 899 (See Fig. 3 for location). Thick vertical line indicates the penetration of the borehole. The enhanced lines on the section indicate the boundaries between acoustic formations 1A, 1B, 2, and 3, defined by Groupe Galice (1979) (see "Integration of Seismic Profiles with Observations from the Site" section, this chapter). The angular unconformity between acoustic formations 1A and 1B is described in the text. Vertical exaggeration is about 10:1.
