Dome A冰川学研究进展及深冰芯计划展望

目前，位于东南极冰盖分冰岭中心的冰穹-Dome A已成为深入理解南极冰盖演化、稳定性和找寻地球气候久远记录的研究热点。通过整理总结在Dome A获得的冰川学研究进展，结合国际冰芯科学研究计划(International Partnerships in Ice Core Sciences，简称IPICS)有关寻找最古老冰芯的相关资料，对Dome A的气象要素、地貌、冰厚、冰下地形、冰体流速、冰盖内部结构等环境特征进行归纳分析，讨论Dome A冰川学的最新发展及其对深冰芯钻探计划的影响，并分析概述Dome A深冰芯钻探需考虑的问题和未来发展动向。

REVIEW OF THE GLACIOLOGICAL RESEARCH PROGRESS AND FUTURE DEVELOPMENT OF DEEP ICE CORE PLAN AT DOME A, EAST ANTARCTICA

Dome A,the highest ice divide in the East Antarctic Ice Sheet,is considered a likely place for gaining understanding of the evolution of the Antarctic Ice Sheet and finding an ice core with climate records reaching back one million years.For this study we collected the information derived from the results of glaciology research at Dome A,and coupled them with the information on finding the oldest ice core in documents from the International Partnerships in Ice Core Sciences.Consequently,the meteorology,landform,ice thickness,subglacial topography,ice velocity,internal structure and other environmental information at Dome A,are summarized.In addition,the new glaciological progress and the future development of deep-ice-core drilling plan in the Dome A area are discussed.
