Although the ITCZ is thought to experience the largest shifts in position during deglacial stadial events, the magnitude of shifts has proven difficult to reconstruct, in part because of a paucity of high-resolution records, particularly those including spatial components. Here, we track the position of the ITCZ from 150-110 ka at three sites in the central equatorial Pacific at sub-millennial time resolution. Our results provide the first evidence of large, abrupt changes in tropical climate during the penultimate deglaciation, coincident with North Atlantic Heinrich Stadial 11 (~136-129 ka). We identify this event both as a northern hemisphere increase in aeolian dust and as a shift in the mean position of the ITCZ a minimum of four degrees southwards at 160°W.","author":{"name":"Jacobel, A.W., J.F.
