Glacial and Paleoclimate Record of the Southern Andes, 46 Degrees South, for the Late Pleistocene

该奖项旨在支持在南美洲中纬度地区建立连续的冰川作用记录，并与附近的冰芯记录和冰海序列进行比较。将开展实地工作，以详细绘制冰碛和冰水侵蚀阶地。 将进行地表暴露年代测定，以提供一个高分辨率的年代地层框架，在该框架内可以放置古气候数据。 将进行土壤分析，以提供该地区的土壤湿度历史。 将进行的其他分析，以微调暴露表面测年，包括更好地估计巨石侵蚀率，并完善宇宙成因核素的当地生产率。这个拟议的研究中心对南半球冰川作用连续高分辨率记录发展的更广泛影响。 这一记录的成功开发有可能回答有关北方和南半球气候变化同步性的基本问题。

This award is to support research that will develop a continuous record of glaciation over the last two to three glacial cycles in mid latitude South America that can be compared to nearby ice core records and glaciomarine sequences.Field work will be undertaken to map moraines and outwash terraces in detail. Surface exposure dating will be carried out to provide a high-resolution chronostratigraphic framework within which paleoclimate data can be placed. Soil analyses will be performed to provide soil-moisture history for the region. Other analyses that will be performed to fine-tune exposure surface dating include better estimates of boulder erosion rates, and refinement of local production rates for cosmogenic nuclides. The broader impacts of this proposed research center on the development of a continuous high resolution record of southern hemisphere glaciation. Successful development of this record holds the potential for answering fundamental questions regarding synchrony of climate change in the northern and southern hemispheres.
