Figure 3. Click on figure for larger image. Three bathymetry profiles across Pulley Ridge within the study area. The seafloor west of the ridge is 72-82 m deep, while east of the ridge the seafloor shoals to 68-70 m. The crest of the ridge is a narrow peak that stands 2-3 m above the rest of the ridge on the northern two profiles, and on the southern profile the crest of the ridge is broader and stands only about 1 m above the adjacent ridge. Profile locations are shown in Figure 2.
