| We present a benthic foraminiferal multiproxy record of eastern equatorial Atlantic (EEA) middepth water (1295m) covering the last deglacial. We show that EEA middepth water temperatures were elevated by 3.90.5 degrees C and 5.21.2 degrees C during Heinrich event 1 (H1) and Younger Dryas (YD), respectively. The radiocarbon content of the EEA middepth during H1 and YD is relatively low and comparable to the values of the pre-H1 episode and BOlling-AllerOd, respectively. A transient Earth system model simulation, which mimics the observed deglacial Atlantic Meridional Overturning Circulation (AMOC) history, qualitatively reproduces the major features of the EEA proxy records. The simulation results suggest that fresh water-induced weakening of the AMOC leads... |
