This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).The proposed research will quantify the hydrological and biogeochemical effects of shallow permafrost on habitat suitability for soil ecosystems in the Antarctic Dry Valleys. The role of permafrost processes in the Dry Valleys ecosystem is poorly understood, therefore definition of relationships among permafrost, soil moisture, hyporheic zones, and geochemical brines is an important advance. The investigators will apply mapping techniques developed for planetary geology missions, including remote mapping and geomorphic analysis, to Antarctic permafrost. This effort will be combined with ecological, hydrological, and geochemical characterization, enabling documentation of permafrost effects on water and nutrient cycling in Antarctic soil ecosystems. Antarctic results will guide emerging astrobiological interpretation of permafrost landforms on Mars. The research partnership combines a postdoctoral geologist from a planetary permafrost background and LTER interdisciplinary scientists, to provide new perspectives for understanding physical/biological processes permafrost habitats. The fellowship will advance the investigator's career goals of becoming a university scientist, and will provide cross-training between planetary geology, earth sciences and ecological sciences. Direct societal impacts will be derived from interactions with diverse undergraduates through teaching and research mentoring at the urban Portland State University campus. K-12 teacher and student field experiences sponsored by the Schoolyard LTER will broaden public awareness of Antarctic research experiences.

该奖项是根据2009年的《美国回收与再投资法》（公法111-5）资助的。拟议的研究将量化浅冻土对南极干谷土壤生态系统的栖息地适合栖息地的水文和生物地球化学作用。多年冻土过程在干谷生态系统中的作用鲜为人知，因此对多年冻土，土壤水分，低潮区和地球化学盐水之间关系的定义是重要的进步。研究人员将将开发的映射技术应用于行星地质任务（包括远程映射和地貌分析），将其应用于南极冻土。这项工作将与生态，水文和地球化学表征相结合，从而有助于对南极土壤生态系统中对水和养分循环的多年冻土影响的文献。南极的结果将指导对火星上多年冻土地面的新兴天体学解释。该研究伙伴关系结合了一位来自行星佛罗斯特背景和lter跨学科科学家的博士后地质学家，以提供新的观点，以理解永久冻土栖息地的物理/生物过程。 奖学金将促进研究者成为大学科学家的职业目标，并将在行星地质，地球科学和生态科学之间提供交叉训练。 直接的社会影响将通过在城市波特兰州立大学校园的教学和研究指导与多样化的本科生的互动中衍生出来。由校园lter赞助的K-12老师和学生实地经验将扩大公众对南极研究经验的认识。
