Abstract

During the middle and late Eocene (∼48-34 Myr ago), the Earth's climate cooled_1,2 and an ice sheet built up on Antarctica. The stepwise expansion of ice on Antarctica_3,4induced crustal deformation and gravitational perturbations around the continent. Close to the ice sheet, sea level rose_5,6despite an overall reduction in the mass of the ocean caused by the transfer of water to the ice sheet. Here we identify the crustal response to ice-sheet growth by forcing a glacial-hydro isostatic adjustment model₇ with an Antarctic ice-sheet model. We find that the shelf areas around East Antarctica first shoaled as upper mantle material upwelled and a peripheral forebulge developed. The inner shelf subsequently subsided as lithosphere flexure extended outwards from the ice-sheet margins. Consequently the coasts experienced a progressive relative sea-level rise. Our analysis of sediment cores from the vicinity of the Antarctic ice sheet are in agreement with the spatial patterns of relative sea-level change indicated by our simulations. Our results are consistent with the suggestion₈ that near-field processes such as local sea-level change influence the equilibrium state obtained by an icesheet grounding line.
