Comment:

Core EW37JPC was subsampled at 2 cm intervals over the interval 777-1330 cm. The samples were freeze-dried, weighed, placed in deionized water, and spun for an hour. The wet samples were washed through 63 μm sieves, and the coarse fraction retained in the sieves was dried, weighed, and transferred to glass vials. The coarse fraction was dry sieved at >150 μm, from which the Cibicidoides wuellerstorfi tests were picked. The δ18O measurements on Cibicidoides wuellerstorfi tests were conducted with a Thermo Delta V Plus gas-source isotope-ratio mass spectrometer equipped with a Kiel IV individual acid-bath sample preparation device at the Lamont-Doherty Earth Observatory of Columbia University stable isotope laboratory. The long-term standard deviation of measurements made on standard carbonate NBS19 was 0.06 ‰. One to three separate stable isotope analyses were at each depth except when the abundance of Cibicidoides wuellerstorfi was low. When duplicates were available, the average was presented for each sample.
