Color version of Figure 5a, located in Figure 2. The interpreted version of this figure is shown in black and white in the published article. Vertical exaggeration is about 25 at the seafloor on this migrated profile. Mid and late Cenozoic strata downlap onto a regional unconformity (top RSS1). The inset is located by the dashed box, and is shown with much less vertical exaggeration (3.4 at seafloor). An angular unconformity (RSU7) is clearly seen in the inset.
