Online Supplemental Figure 3: The chemofacies profile for the Ray 1–13 Core. Hierarchical clustering analysis subdivided the geochemical profiles into seven distinct chemofacies. The sample resolution for this chemofacies profile is 6 inches (15cm). There is a general shift from chemofacies indicating restricted bottom water conditions and clay accumulation at the base to well-circulated bottom water conditions dominated by increasing continental sedimentation at the top of this profile.
