0949398MillerThis grant supports acquisition of a high-pressure liquid chromatography (HPLC) system for amino acid racemization thermochronology and plant pigment analyses, a gamma spectrometer for 210Pb and 137Cs dating of recent sediments and calculation of sedimentation rates, and a microwave digestion system and freeze drier for sample preparation. The equipment will support PI research in Quaternary paleoclimatology, quantitative geomorphology, aquatic ecology and watershed hydrology at the Institute of Arctic and Alpine Research (INSTAAR) at the University of Colorado. PI environmental change research has immediate relevance to our understanding of global and regional climate dynamics and the impacts of climate change on ecosystems. The equipment will support student research training, and active PI outreach efforts to the local K-12 community.***

0949398 Millerthis Grant支持氨基酸种族化热量学和植物色素分析的高压液相色谱（HPLC）系统，210pb和137CS的伽马光谱仪和最近的沉积物的日期和繁殖率的计算以及微型试剂材料和冻结的准备效果，以进行繁殖率和冻结。 该设备将支持科罗拉多大学北极和高山研究所（Instaar）的第四纪古气候，定量地貌，水生生态学和流域水文学研究。 PI环境变化研究与我们对全球和区域气候动态的理解以及气候变化对生态系统的影响有关。 该设备将支持学生研究培训，并为当地的K-12社区进行积极的PI外展工作。***
