Geiger, A. (2013) Thickness Constraints of the Patagonian Ice Sheet Over the Last Glacial Cycle Using Surface Exposure Dating. Project Report. RGS-IBG.
Full text not currently available from Enlighten.
Abstract
The study will provide critical empirical field based constraints of the vertical extent of the Patagonian Ice Sheet over the last glacial cycle. In-situ produced terrestrial cosmogenic nuclides 10Be and 26Al are used to date the surface exposure of erratic boulders and/or bedrock on high altitude ridges/summits (500-2000 m.a.s.l.). This will yield age-elevation correlations, rates of ice surface lowering, and volumetric configurations of the Patagonian Ice Sheet at 49°S over the last glacial cycle. The data will feed into palaeoclimatic reconstructions of Patagonia, southern South America.
