Acquisition of Liquid Chromatography and Sample Preparation Instrumentation for Enhanced Reconstruction of Quaternary Environmental Change

[0949398]米勒这笔拨款支持购买用于氨基酸消旋热年代学和植物色素分析的高压液相色谱（HPLC）系统，用于210Pb和137Cs对近期沉积物定年和沉积速率计算的伽马光谱仪，以及用于样品制备的微波消解系统和冷冻干燥机。该设备将支持PI在科罗拉多大学北极与高山研究所（INSTAAR）的第四纪古气候学、定量地貌学、水生生态学和流域水文学方面的研究。PI环境变化研究与我们对全球和区域气候动力学以及气候变化对生态系统的影响的理解直接相关。这些设备将支持学生的研究培训，并积极为当地K-12社区提供PI服务

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.***
