Abstract: The grounding line of the ice sheet in the Ross Sea, Antarctica, retreated between the Last Glacial Maximum and the present. However, the timing of the retreat and the interplay of factors controlling ice stability in this region1 remain uncertain. Here we use 180 radiocarbon dates to reconstruct the chronology of moraine construction on read more Accumulation and Marine Forcing of Ice Dynamics in the Western Ross Sea during the Last Deglaciation – Nature Geoscience – Hall/Denton et al.
