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. ***

9318515丹顿奖是对一项为期两年的研究的支持，该研究旨在改善对上新世冰川历史和横贯北极山脉的景观演变的理解，以调和关于南极气候和相关的上新世暖期冰川反应的相互矛盾的假设。将要研究的新领域是皇家学会山脉，它拥有广泛的无冰区域，并毗邻干燥的山谷和大型离岸火山。这些独特的情况表明，关键的上新世年代学、地层学、古气候和地表隆起数据将在该地区得到很好的保存。将从皇家学会范围获得的冰川和构造信息应该会极大地阐明南极科学中两个相互交织的重要问题：上新世冰盖的稳定性和横贯北极山脉的演化。***
