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.%目前,在东南极冰盖分冰岭中心的冰穹A( Dome Argus,又称Dome A)开展冰川学及深冰芯研究已成为深入探讨南极冰盖演化和找寻地球最古老冰芯气候记录的热点.本文介绍了在冰穹A已获得的冰川学各项研究的进展,并结合国际冰芯科学研究计划(International Partnerships in Ice Core Sciences,IPICS)中有关寻找最古老冰芯的相关资料,对冰穹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综合归纳分析,讨论冰穹A冰川学的最新发展趋势,其对今后深冰芯钻探计划的潜在影响,以及冰穹A深冰芯钻探需考虑的问题和未来发展动向.
