Comparison of Malawi paleo-lake level reconstructions with eccentricity, insolation (low latitude), and the LR04 benthic stack (high latitude). Gray bars represent intervals of low (400 ky) eccentricity when Malawi lake level stabilized at highstand conditions. Red arrows represent the presence of the MPT in Malawi, from frequent low lake levels before ∼900 ka to frequent high lake level conditions after. (A) Calibrated lake level from PC(1) from Malawi site 1 (see SI Appendix, Fig. S7, and supplemental text for calibration routine). (B) Bulk TOC measurements from site 1. (C) Calcium abundance from scanning X-ray fluorescence (kcpm = thousand counts per minute). (D) δ18O LR04 benthic stack (29). (E) Eccentricity and insolation from 10 °S.
