Landscape Analysis Applied to Pliocene Ice-Sheet Sensitivity and Transantarctic Mountains Evolution

9318515丹顿该奖项是为了支持一项为期两年的研究，以提高对上新世冰川历史和跨南极山脉景观演变的理解，以调和南极气候的相互冲突的假设，并在上新世温暖的时间间隔相关的冰的反应。 将要研究的新领域是皇家学会山脉，该山脉有广泛的无冰地区，毗邻干谷和大型近海火山。 这些独特的环境表明，关键上新世年代，地层，古气候和地表隆起数据将在这一地区保存完好。 来自皇家学会山脉的冰川和构造信息应该能极大地澄清南极科学中两个重要的、相互交织的问题：上新世冰盖的稳定性和横贯南极山脉的演变。 ***

9318515 Denton This award is for support for a two year study to improve the understanding of Pliocene glacial history and landscape evolution of the Transantarctic Mountains in order to reconcile conflicting hypotheses of Antarctic climate and associate ice response during Pliocene warm intervals. The new field area to be studied is the Royal Society Range, which has extensive areas free of ice and is adjacent both to the Dry Valleys and to large off-shore volcanoes. These unique circumstances suggest that critical Pliocene chronologic, stratigraphic, paleoclimatic, and surface uplift data will be well preserved in this area. The glacial and tectonic information that will be derived from the Royal Society Range should greatly clarify two important and intertwined problems of Antarctic science: Pliocene ice-sheet stability and the evolution of the Transantarctic Mountains. ***
