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

9318515 Denton该奖项是为了支持一项为期两年的研究，该研究旨在提高对上新世冰川历史和横贯南极山脉景观演变的理解，以调和有关上新世暖期南极气候和相关冰响应的相互矛盾的假设。要研究的新领域是皇家学会山脉，它有广阔的无冰地区，毗邻干谷和大型离岸火山。这些独特的环境表明，该地区上新世的年代学、地层、古气候和地表隆起的关键资料将得到很好的保存。从皇家学会山脉获得的冰川和构造信息将极大地澄清南极科学的两个重要且相互交织的问题：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. ***
