Combining ice core records and ice sheet models to explore the evolution of the East Antarctic Ice sheet during the Last Interglacial period

► This paper explores plausible changes in the East Antarctic Ice sheet on the surface elevation at ice core sites. ► At least half of the early LIG optimum in ice core records could be explained by a reduced thickening across East Antarctica. ► This effect should be considered when estimating LIG temperatures. ► A simulated retreat within Wilkes -Aurora basins produces a large elevation-driven response. ► These results might be able to constrain the contribution of this region to elevated LIG sea levels.
