Response to Comment on “Deep-Sea Temperature and Ice Volume Changes Across the Pliocene-Pleistocene Climate Transitions”

Yu and Broecker argue that the paleoceanographic interpretation of our 3.2-million-year record of North Atlantic deep-sea temperature hinges on the determination of whether temperature or carbonate saturation is the primary driver of benthic foraminiferal magnesium/calcium ratios from the North Atla...

Description
Summary:Yu and Broecker argue that the paleoceanographic interpretation of our 3.2-million-year record of North Atlantic deep-sea temperature hinges on the determination of whether temperature or carbonate saturation is the primary driver of benthic foraminiferal magnesium/calcium ratios from the North Atlantic. Here, we present evidence supporting our argument that bottom-water temperature variability is the primary control on benthic foraminiferal Mg/Ca at our site.
