Ice Sheet and Solid Earth Influences on Far-Field Sea-Level Histories

Sophie E. Bassett,1 Glenn A. Milne,1* Jerry X. Mitrovica,2 Peter U. Clark3

Previous predictions of sea-level change subsequent to the last glacial maximum show significant, systematic discrepancies between observations at Tahiti, Huon Peninsula, and Sunda Shelf during Lateglacial time (~14,000 to 9000 calibrated years before the present). We demonstrate that a model of glacial isostatic adjustment characterized by both a high-viscosity lower mantle (4 x 1022 Pa s) and a large contribution from the Antarctic ice sheet to meltwater pulse IA (~15-meters eustatic equivalent) resolves these discrepancies. This result supports arguments that an early and rapid Antarctic deglaciation contributed to a sequence of climatic events that ended the most recent glacial period of the current ice age.
