a δ18Ob from Site U1406 (bright red, this study). EMI (Early Miocene Interval), OMT (Oligocene-Miocene Transition), LOW (Late Oligocene Warming), and MOGI (Mid-Oligocene Glacial Interval). Arrows indicate abrupt decreases in δ18Ob at Site U1406. b and c δ18Ob at sites 926 (dark red)29 and 1264 (yellow)19, respectively. d and e La2004 astronomical solutions41 for obliquity and eccentricity, respectively, with obliquity instantaneous amplitude and long-term eccentricity modulations of ~405 kyr and ~2.4 Myr. Site locations shown in Fig. S1.
