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日在威斯康星州麦迪逊举行的一次国际研讨会，其主要目标是整合和综合数据，并启动关于编制南极地区，特别是麦克默多干燥山谷(MDV)的永久冻土和地面冰条件和土壤地图的讨论。智力优势：南极洲拥有世界90%的冰，并对南半球和全球大气和冰冻圈系统产生主要影响。南极大陆只有0.3%是无冰的，MDV是南极洲最大的无冰区域(4000平方公里，占总面积的25%)。除了冰川厚度足以导致压力融化的地方外，整个大陆都有永久冻土。尽管在南极洲的无冰区研究土壤已有近100年的历史，但目前还没有全面的土壤信息电子数据库，也没有使用现代全球分类的土壤地图。在这项工作计划中，我们建议为存档数据和绘制南极地区(60oS)的永久冻土和地面冰特征和土壤地图奠定基础，重点是MDV。由一个国际团队汇编的这些地图将构成南半球第一张永久冻土和土壤地图，并将补充北半球出版的地图。更广泛的影响：由于温度和永冻土分布的广泛、系统的变化可能对南极地区的温室气体通量和人类基础设施产生深远影响，因此必须优化观测和分析程序。同样，有必要为非洲大陆的自然资源管理收集基准分析数据和土壤地图。这次研讨会将汇集来自许多南极条约国家的永冻土科学家、土壤学家、地理信息系统和绘图专家，以汇编数据，最终产生第一份显示南半球永冻土和土壤分布的全面地图。

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.
