International Workshop on Antarctic Permafrost and Soils; November 15-19, 2004; Madison, WI

该奖项支持将于2004年11月15日至19日在威斯康辛州麦迪逊举行的一个国际研讨会，其主要目标是整合和综合数据，并开始讨论准备南极地区，特别是麦克默多干谷（MDV）的永久冻土、地面冰条件和土壤的地图。知识价值：南极洲拥有世界上90%的冰，对南半球和全球大气和冰冻圈系统具有重要影响。南极洲只有0.3%的土地是无冰的，其中MDV是南极洲最大的无冰地区（4000平方公里，占总面积的25%）。永久冻土层覆盖着整个大陆，除了那些冰川厚到足以导致压力融化的地方。尽管在南极洲无冰地区对土壤进行了近100年的研究，但目前还没有全面的土壤信息电子数据库，也缺乏利用现代全球分类方法绘制的该大陆土壤地图。在本工作计划中，我们建议以MDV为重点，为南极地区（60年代）多年冻土、地冰特征和土壤的数据归档和制图奠定基础。这些地图由一个国际小组汇编，将构成南半球第一批永久冻土和土壤地图，并将补充已出版的北半球永久冻土和土壤地图。更广泛的影响：由于永久冻土带温度和分布的广泛、系统的变化可能对温室气体的通量和南极地区的人类基础设施产生深远的影响，因此优化观测和分析程序至关重要。同样，也需要为非洲大陆的自然资源管理收集基准分析数据和土壤图。本次研讨会将汇集来自许多《南极条约》国家的永久冻土科学家、土壤科学家、地理信息系统和制图专家，汇编数据，最终生成显示南半球永久冻土和土壤分布的第一张综合地图。

This award supports an international workshop to be held Nov. 15-19, 2004 in Madison, Wisconsin, with the main goals of integrating and synthesizing data and initiating discussions on preparation of maps of permafrost and ground-ice conditions and soils of the Antarctic region, especially in the McMurdo Dry Valleys (MDV). Intellectual Merit: Antarctica contains 90% of the world's ice and exerts a predominant influence on southern hemisphere and global atmospheric and cryospheric systems. Only 0.3% of the continent is ice-free, with the MDV constituting the largest ice-free area in Antarctica (4,000 km2, or 25% of the total). Permafrost underlies the entire continent, except where glaciers are thick enough to induce pressure melting. Although soils have been studied in ice-free areas of Antarctica for nearly 100 years, no comprehensive electronic database exists for soils information and soil maps using modern global taxonomies are lacking for the continent. In this work plan, we propose to lay the groundwork for archiving data and constructing maps of the permafrost and ground-ice features and soils of the Antarctic region (60oS), emphasizing the MDV. Assembled by an international team, these maps would constitute the first permafrost and soil maps of the southern hemisphere and would complement those published for the northern hemisphere. Broader Impacts: Because widespread, systematic changes in the temperature anddistribution of permafrost could have profound effects on the flux of greenhouse gases and on the human infrastructure in the Antarctic region, it is critical that observation and analysis procedures be optimized. Similarly, there is a need to collect benchmark analytical data and soil maps for natural resource management of the continent. This workshop will bring together permafrost scientists, soil scientists, and GIS and mapping experts from many of the Antarctic Treaty nations to compile data that will eventually lead to the generation of the first comprehensive maps showing the distribution of permafrost and soils in the southern hemisphere.
