Millennial-scale events first characterized in Greenland ice cores as abrupt warming from a cold stadial state to a warmer interstadial state, followed by a return to a cold stadial state (Dansgaard et al., 1993), and traced in the ocean via deposits of ice-rafted sand grains (Bond and Lotti, 1995). Named after Willi Dansgaard and Hans Oeschger by Bond and Lotti (1995). An example of a D–O event during the most recent deglacial transition is the Bølling–Allerød interstadial. Warm D–O events in Greenland are associated with cooling events in Antarctica (Blunier and Brook, 2001) through ocean thermohaline circulation (Stocker and Johnsen, 2003). (English)
