Figure 9. Downhole variations (wt%) in measured calcium carbonate, total organic carbon (TOC), and terrigenous matter in Hole 1002C compared to the ¹⁸O stratigraphy for this site. Data are plotted against estimated age using the age model shown in Figure 8. In general, carbonate and TOC contents tend to be high in sediments of interglacial age, whereas terrigenous contents typically increase in glacial sediments.
