Figure F21. Match of total organic matter (Corg) with glacial-interglacial climate fluctuations. A. Statistical modeling of TOC content in core GeoB1028 taken on Walvis Ridge. Input is global sea level, as reflected in a global oxygen-isotope signal (806sox) and July insolation at 15°N (Jul15N). From Berger, Wefer, Richter, et al. (1998). B. Direct match of TOC and oxygen isotope index within core GeoB1028, based on Globigerinoides ruber. TOC is plotted upside down (negC). (Both series standardized to mean = unity and std. = 0.25.) Data are from Geowissenschaften Bremen (analysts: R. Schneider and H. Schmidt).
