Orbital Spectral Mapping of Surface Compositions in the Antarctic Dry Valleys: Regional Distributions of Secondary Mineral-Phases as Climate Indicators

摘要本项目利用Aster和Hyperion遥感数据，结合野外观测和实验室分析，绘制了南极麦克默多干旱河谷的土壤图。其目的是利用矿物丰度、组成和空间异质性来研究小气候和地表特征之间的联系。这些山谷是地球上最独特的景观之一。这些结果将与了解它们的地质、生物和气候历史有关，并提供对火星景观的洞察。主要的更广泛的影响是研究生教育和涉及K12教师的课程开发。

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.
