(ESH) COLLABORATIVE RESEARCH: Test of the synchromicity of Alpine Glacier Responses to Regional High Amptitude Climate Reversals: Southern Andes

这一合作提案旨在为一项研究提供支持，该研究旨在检查南美洲南部三个精心选择的地点的冰缘从最后一个冰川最大位置的多个裂片退缩的时间。火地岛冰冠出口裂片的三个间隔较宽且绘制良好的冰碛序列的数据将有助于评估出口裂片对气候变化响应的同步性。宇宙成因3He， 10Be和26a1方法的组合将用于确定每个冰碛层的冰川退缩日期。

This collaborative proposal seeks support for a study to examine the timing of ice-margin retreat from the last glacial maximum positions of multiple lobes at three carefully selected sites in southern South America. Date from the three widely spaced, well mapped moraine sequences from outlet lobes of the Tierra del Fuego ice cap will help evaluate the synchroneity of outlet lobe responses to climatic changes. A combination of cosmogenic 3He, 10Be, and 26 A1 methods will be used to date glacial retreat from each of the moraine sequences.
