ISAES Session 23 - "Quaternary history of the Antarctic Ice Sheet: A marine perspective"
We would like to draw your attention to the session “Quaternary history of the Antarctic Ice Sheet: A marine perspective” at the 2011 ISAES in Edinburgh, 10-16th July. We encourage you to submit abstracts to it via the ISAES website (details below) and look forward to seeing you in Edinburgh in July 2011.
The abstract deadline is 31 March 2011.

“Quaternary history of the Antarctic Ice Sheet: A marine perspective”
Ice sheet models require accurate geological data to constrain them and the Quaternary marine record represents one of the most detailed and complete archives of past ice sheet variability in Antarctica. Not only can this data help to constrain and refine ice sheet models seeking to predict future changes but it also helps to define ice-sheet processes that are relevant on human time-scales. The Last Glacial Maximum (LGM) left a detailed imprint of former ice extent and behaviour in shelf sediments and geomorphology, yet the style and timing of deglaciation remains uncertain for many sectors of the ice sheet. Several studies suggest that the deglaciation of the East and West Antarctic ice sheets was asynchronous, with model reconstructions indicating that the major phase of deglaciation occurred during the Holocene. On glacial-interglacial time-scales, it has been suggested that the West Antarctic Ice Sheet may have undergone catastrophic change (collapse) on at least one occasion during the Quaternary, although the marine evidence for such an event is inconclusive.
The aim of this session is to draw together marine geological/geophysical evidence for ice sheet sensitivity including: offshore evidence for Quaternary deglaciations (specifically evidence for ice sheet collapse and post-LGM ice retreat histories), ice shelf history, palaeo-ice flow changes from marine sediment cores and geomorphology, records of palaeo sea-level as well as modelling ice sheet change(s). We encourage contributions from all sectors of Antarctic continental shelf, slope, rise and Southern Ocean relating to ice sheet variability. We also welcome papers documenting recent technological/methodological advances for dating marine sediments.
