Figure 3. Bathymetry of Broken Ridge (GEBCO, 1984). Filled stars = previous DSDP and ODP drill sites that recovered igneous basement; open stars = sites that bottomed in sediment. Black squares = dredge locations (DR-X) that recovered igneous basement. Open and closed circles = proposed drill sites (KIP-9B and 9C) for Leg 183 as in Figure 2. The seismic line used to select these sites = a black line with cruise identifier (C = Robert Conrad). Contour interval is 500 m.
