Figure 21. Comparison of Dansgaard/Oeschger events in GISP-2 (oxygen isotopes from Grootes et al. [1993] and Stuiver et al. [1995]; time scale from Sowers et al. [1993] and Meese et al. [1994]) to the Northern California CaCO3 Mass Accumulation Rate stack (Lyle et al., Chap. 11, this volume). The stack is made from Sites 1018, 1020, and the piston cores EW9504-17 and W8709-13, as described in Lyle et al. (Chap. 11, this volume). Within MIS 2-4 there is a correspondence between D/O events and CaCO3 events. The weakest coherence is in late MIS 3 (D/O Events 4-10).
