Ruth M.K. Plets, S. Louise Callard, J. Andrew G. Cooper, Joseph T. Kelley, Daniel F. Belknap, Robin J. Edwards, Antony J. Long, Rory J. Quinn, Derek W.T. Jackson Abstract The interplay of eustatic and isostatic factors causes complex relative sea-level (RSL) histories, particularly in paraglacial settings. In this context the past record of RSL is important in understanding ice-sheet history, earth rheology and resulting glacio-isostatic adjustment. Field data to develop sea-level reconstructions are often limited to shallow depths and uncertainty exists as to the veracity of modelled sea-level curves. We use seismic stratigraphy, 39 vibrocores and 26 radiocarbon dates to investigate the deglacial history of Belfast Lough (Northern Ireland) and reconstruct past RSL.
