Fig. 3.

High-resolution bulk stable isotope and percent carbonate data from the Millville core (IODP Leg 174AX) through the onset of the CIE. Depth scales are in meters (Upper) and feet (Lower; the drillers used 10-ft drill rods and feet units are preserved here to facilitate comparison with the original core descriptions). The δ¹³C (red), δ¹⁸O (blue), and CaCO₃ (green) records were generated by sampling the slabbed Millville cores at 2-mm intervals. Intervals with no data reflect too little or no CaCO₃ (<0.1%) are shown by the gray bars. The position of the clay couplets is denoted by the inverted triangles at top.
