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.

本项目利用Aster和EAST遥感数据，结合野外观测和实验室分析，对南极洲麦克默多干旱河谷的土壤进行制图。目的是利用矿物丰度、成分和空间异质性来研究小气候和地表特征之间的联系。山谷是地球上最独特的景观之一。这些结果将有助于了解它们的地质、生物和气候历史，并提供对火星景观的深入了解。主要的更广泛的影响是涉及K12教师的研究生教育和课程开发。
