Table S7 Revised tuning models (Model I and II) for the Upper Burgi Member in Areas 102 and 131, based on 87Sr/86Sr isotopic data from fish fossils (Joordens et al. 2011, 2013), the 65ºN summer insolation curve of the La2004(1,1) solution (Laskar et al. 2004) for the time interval 1860 – 2000 ka, and the revised KBS age (1879.1 ± 1.8 ka).
