AbstractThis project uses Aster and Hyperion remote sensing data combined with field observations and laboratory analysis to map soils in the McMurdo Dry Valleys of Antarctica. The goal is to use mineral abundances, compositions, and spatial heterogeneities to investigate the connections between microclimate and surface characteristics. The valleys are one of the most unique landscapes on earth. The outcomes will be relevant to understanding their geologic, biologic, and climactic history, and offer insight into the Martian landscape. The main broader impacts are graduate education and curriculum development involving K12 teachers.

摘要此项目使用Aster和Hyperion遥感数据与现场观测和实验室分析相结合，以绘制南极洲McMurdo Dry Valleys中的土壤。目的是使用矿物丰度，组成和空间异质性来研究微气候和表面特征之间的联系。山谷是地球上最独特的景观之一。结果将与了解其地质，生物学和高潮历史有关，并提供对火星景观的见识。更广泛的影响是涉及K12教师的研究生教育和课程发展。
