Abstract ATM-9417818 Wake, Cameron University of New Hampshire Title: Ice Core Records from Monsoon Asia The highlands of central Asia possess a diversity of natural archives from which detailed paleoclimatic records can be developed (e.g., lake sediments, loess, tree rings, ice cores, glacier fluctuations, geomorphologic features). Despite this potential, relatively little is known concerning climatic changes in the region over time scales ranging from centuries to hundreds of thousands of years. The primary objective of this project is to develop multi-variate, well-dated, high-resolution (annual) paleoclimatic records for monsoon Asia for the last 500 to 1000 years. This project will focus on the chemical and physical analysis of deep (approximately 200m) firn/ice cores recovered from two high elevation (6000m) glaciers in the Nepalese Himalaya. Time-series developed from the physical and chemical analysis of the ice core will form the basis of a regional paleoclimatic record. The proposed ice core research in monsoon Asia represents a key component of the Himalayan Interdisciplinary Paleoclimate Project (HIPP). HIPP is aimed at improving our understanding of the behavior of the Indian and Plateau monsoons over the past 2000 years, 20,000 years, and beyond. Multi-variate paleoclimatic records from a wide variety of natural archives in the highlands of Central Asia. In addition, multivariate, high resolution ice core records from the Himalayas will be compared directly with similar detailed ice core data records recovered from Tibet, Peru, Greenland and Antarctica, thereby developing a broader, more globally comprehensive ice core data base from which to investigate global change.

摘要ATM-9417818 Wake，卡梅隆新罕布什尔州大学标题：亚洲季风的冰芯记录 中亚高原拥有多种多样的自然档案，从中可以开发出详细的古气候记录（例如，湖泊沉积物、黄土、树木年轮、冰芯、冰川波动、地貌特征）。 尽管有这种潜力，但人们对该区域从几个世纪到几十万年的时间尺度上的气候变化知之甚少。 该项目的主要目标是为亚洲季风区建立多变量、日期准确、高分辨率（年度）的过去500至1000年的古气候记录。 该项目将侧重于对从尼泊尔喜马拉雅山两个高海拔（6000米）冰川中采集的深层（约200米）雪/冰芯进行化学和物理分析。 从冰芯的物理和化学分析得出的时间序列将构成区域古气候记录的基础。 亚洲季风区冰芯研究是喜马拉雅跨学科古气候计划（HIPP）的重要组成部分。 HIPP旨在提高我们对过去2000年、20，000年及以后印度和高原季风行为的理解。 来自中亚高地各种自然档案的多变量古气候记录。 此外，将把喜马拉雅山多变量高分辨率冰芯记录与从西藏、秘鲁、格陵兰和南极洲获得的类似详细冰芯数据记录直接进行比较，从而建立一个更广泛、更全面的冰芯数据库，据以调查全球变化。
