(Table S4) Carbon and oxygen isotope values for pedogenic carbonate samples collected from Polecat Bench cores A and B organized by stratigraphic level

DEPTH, sediment/rock = (Meters Composite Depth, MCD).For samples with replicate analyses, the average carbon or oxygen isotope values are listed. Samples in italics were not included in the composite d13C record analyzed here, based on the screening procedure described in the Methods.
