Figure 1. Map showing the location of ODP Leg 164 sites (large, solid circles), DSDP sites (solid triangles), and piston cores (small circles and squares; Borowski et al., 1997). Bathymetric contours are in meters after Uchupi (1968). The outline of bottom-simulating reflectors (BSRs; shaded) is based on the mapping of Dillon and Paull (1983).
