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日在威斯康星州的麦迪逊举行的国际研讨会，其主要目标是整合和综合数据，并就南极地区，特别是麦克默多干旱山谷（MDV）的永久冻土和地冰条件及土壤地图的编制展开讨论。智力优势：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产生重大影响。只有0.3%的大陆是无冰的，MDV构成了南极洲最大的无冰区（4，000平方公里，占总面积的25%）。永久冻土覆盖了整个大陆，除了冰川厚度足以引起压力融化的地方。虽然对南极洲无冰区土壤的研究已进行了近100年，但没有关于土壤信息的综合电子数据库，也没有使用现代全球分类法绘制的南极洲土壤图。在本工作计划中，我们建议为存档数据和绘制南极地区（60 ° S）永久冻土和地冰特征和土壤地图奠定基础，重点是MDV。这些地图由一个国际小组绘制，将构成南半球的第一幅永久冻土和土壤地图，并将补充已出版的北方地图。 更广泛的影响：由于温度和永久冻土分布的广泛、系统性变化可能对温室气体通量和南极地区的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，需要收集基准分析数据和土壤图，用于非洲大陆的自然资源管理。该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，最终将导致生成第一张显示南半球永久冻土和土壤分布的综合地图。

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.
