Prentice et. al: OPP 0003792Kurz: OPP 0003873This award supports a one year lab-based study which will allow a detailed calibration between ground-penetrating radar (GPR) data and existing drilled sediment sequences from Lower Taylor Valley, which will improve the lithostratigraphy in the region. In addition, exposure-age dating of existing samples from the Hjorth Hill locality in Taylor Valley will also be carried out in order to test the multiple drift-sheet interpretation of the GPR data. All of the goals described in the revised scope of work are consistent with the goal of the original proposal, which was to resolve multiple WAIS glaciations and regional climate change. This work is complementary to studies of the variability of the West Antarctic ice sheet (WAIS) and will help to improve resolution of alpine and piedmont glacier variability during the latest Pleistocene.

普伦蒂斯等艾尔：该奖项支持一项为期一年的实验室研究，该研究将允许对探地雷达（GPR）数据和下泰勒谷现有钻探沉积物序列进行详细校准，这将改善该地区的岩石地层学。 此外，还将对泰勒谷Hjorth Hill地区的现有样品进行年代测定，以测试探地雷达数据的多重漂移层解释。 修订后的工作范围中描述的所有目标都与原始提案的目标一致，即解决多个WAIS冰川和区域气候变化问题。 这项工作是对南极西部冰盖变化研究的补充，将有助于提高对最近更新世期间高山和皮埃蒙特冰川变化的认识。
