Timing of the Last Glacial Maximum from observed sea-level minima
Yusuke Yokoyama,Yusuke Yokoyama,Kurt Lambeck,Patrick De Deckker,Paul Johnston,L. Keith Fifield +5 more
TL;DR: This work uses faunal assemblages and preservation status of the sediments to distinguish open marine, shallow marine, marginal marine and brackish conditions, and estimates the timing and the mass of the ice sheets using radiocarbon dating and glacio-hydro-isostatic modelling to estimate the maximum volume and timing of the initial melting phase.
Journal ArticleDOI
Refining the eustatic sea-level curve since the Last Glacial Maximum using far- and intermediate-field sites
TL;DR: In this paper, the eustatic component of relative sea-level change provides a measure of the amount of ice transferred between the continents and oceans during glacial cycles, which has been quantified for the period since the last glacial maximum by correcting observed sea level change for the glacio-hydro-isostatic contributions using realistic ice distribution and earth models.
Journal ArticleDOI
Sea-level change, glacial rebound and mantle viscosity for northern Europe
TL;DR: In this paper, an inverse solution for the sea-level data are sought that include both ice- and earth-model parameters as unknowns, and both global (northwestern Europe as a whole) and regional (subsets of the data) solutions have been made for earth model parameters and ice height scaling parameters.
Journal ArticleDOI
Sea-level at the Last Glacial Maximum: evidence from northwestern Australia to constrain ice volumes for oxygen isotope stage 2
TL;DR: In this article, the Bonaparte Gulf is used to constrain the magnitude and rates of change of ice volumes during the last glacial maximum (LGM) in northwestern Australia.
Journal ArticleDOI
Holocene glacial rebound and sea-level change in NW Europe
TL;DR: Inversion of sea-level observations from a site near the centre of the Fennoscandian ice sheet and from three sites located beyond the margin of the ice sheet at the time of maximum glaciation yield a range of plausible models for the Earth's response and for the ice models.
