MD03-2621 marine sediment core: (a) 6.4–41.6 ka b2k; (b) 40.2–75.4 ka b2k; and (c) 74–109.2 ka b2k. The black solid line is the core reflectance⁶⁴, with the vertical axis reversed. Vertical lines represent transitions detected by the KS test of Bagniewski et al.¹⁹, with colors indicating the direction of the jumps. In this figure, red lines represent a warming event, while blue lines represent a cooling event. In other figures, the meaning of the colors may vary. Grey bars denote warm episodes. Note that all time axes in this paper follow the geological custom of pointing into the past.
