27 lip 2023 · Here we use speleothem-based age models, similar to Bajo et al. 8, to provide improved termination age estimates suitable for evaluating the precession phase of Late Pleistocene terminations.
Instead, we use an age-model devoid of orbital assumptions and apply it to the leading empirical orthogonal function (EOF1) of ten well-resolved marine δ18O records13, a proxy for ice-volume and ocean temperature (Fig 1a). Most simple models of the late Pleistocene glacial cycles have at least four degrees of freedom2, and some have as many as ...
chronologies from three mountain ranges in Alaska that reveal the timing and spatial extent of Late Pleistocene glaciation, and pay particular attention to age of the penultimate glaciation. The most extensive glacier advance of the last glaciation occurred prior to the last global glacial maximum.
27 lip 2023 · PDF | Climate variability over the past 800,000 years has long been described as being dominated by ~100-kyr glacial cycles, and researchers have... | Find, read and cite all the research...
24 mar 2005 · We also present simple stochastic and deterministic models that describe the timing of the late-Pleistocene glacial terminations purely in terms of obliquity forcing.
New luminescence dating brings the first direct Late 19 Pleistocene glacial chronology for the western Alpine foreland and reveals two major glacier 20 advances of similar maximum extent, at ca. 75-60 and ca. 40-30 ka, coinciding with MIS 4 and 21 late MIS 3. We propose that asynchrony in glacial maxima between the western and the
19 cze 2018 · The stratigraphic record of Late Pleistocene glaciations in the Alps is well defined for the Last Glacial Maximum (LGM) thanks to recent chronological and stratigraphic studies.
