Acquisition of an Automated Nutrient Analyzer

0744166里昂这笔赠款支持购买自动营养分析仪，以支持研究，这将受益于快速和精确的同时测定溶解营养浓度（例如，NO32-、NO2-、PO43 -、H4SiO2）。该仪器将支持整个地球科学学院和地理系在俄亥俄州州立大学的教师和学生的研究广度。 示例包括：（1）农业肥料对俄亥俄州区域河流氮动态的影响研究;（2）构造活跃的高位海洋岛屿河流系统化学风化动力学及其对营养限制的影响研究;第三章调查气候变化对美国中部大陆上游草原壶穴洼地湖泊和湿地的水化学和生产力的影响;研究气候变化和土地利用动态对安第斯山脉中部山区冰川河流和地下水水质的影响。

0744166LyonsThis grant supports acquisition of an automated nutrient analyzer to support studies of that will benefit from rapid and precise simultaneous determinations of dissolved nutrient concentrations (e.g., NO32-, NO2-,PO43 -, H4SIO2) in natural waters. The instrument will support a breadth of faculty and student research across the School of Earth Sciences and the Department of Geography at The Ohio State University. Examples include: 1) studies of agricultural fertilizer impacts on the nitrogen dynamics of regional rivers in the state of Ohio; 2) studies of the kinetics of chemical weathering and its effects on nutrient limitation in riverine systems of tectonically active high standing oceanic islands; 3) investigations of the effects of climate change on the aquatic chemistry and productivity ofprairie pothole depressional lakes and wetlands of the upper U.S. midcontinent; and 4) studies of the effects of climate change and land use dynamics on the water quality of mountain glacier fed rivers and groundwaters in the central Andes.
