Collaborative Research: West Antarctic Ice-Sheet and Alpine Glacier Variability During the Latest Pleistocene: An Integrated Radar, Drilling and Exposure-Age Study in McMurdo Sound

Prentice et.Al：OPP 0003792Kurz：OPP 0003873该奖项支持一项为期一年的基于实验室的研究，该研究将允许在探地雷达(GPR)数据和下泰勒山谷现有钻井沉积物序列之间进行详细校准，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曝光年龄测定，以测试对探地雷达数据的多重漂移片解释。修订后的工作范围中描述的所有目标都与最初提案的目标一致，即解决多个WAIS冰川和区域气候变化问题。这项工作是对西南极冰盖(WAIS)可变性研究的补充，将有助于提高最新更新世期间阿尔卑斯山和山前冰川可变性的分辨率。

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.
