Abstract:
We present a new 150,000-year-long, well-dated, high-resolution deep ocean acidity record, which reveals five hitherto undetected modes of stadial ocean ventilation with different consequences for deep-sea carbon storage and associated atmospheric CO2 changes. The data set contains the age model G. bulloides oxygen isotope, IRD counts, N. pachyderma counting, and C. wuellerstorfi B/Ca ratios from sediment core MD95-2039. We also present the new deep-water carbonate ion reconstructions at MD95-2039 using C. wuellerstorfi B/Ca.
