FSML-Analytical Equipment for the St. Croix Watershed Research Station

圣克鲁瓦流域研究站（SCWRS）是明尼苏达科学博物馆（SMM）的生物野外站。 SCWRS的土地和设施位于明尼苏达州和威斯康星州边界的圣克鲁瓦国家风景区河道内。SCWRS提供了对大型中大陆河流系统和相关栖息地进行研究的机会。 该SCWRS成立于1989年，并大大扩大了其物理设施，人员配备和研究活动在干预六年。 经过战略规划的努力，一个现代化的6200平方英尺的研究中心和访问科学家的全年住房设施于1995年建成。1995- 1996年，SCWRS扩大了其常设研究人员，以创建一个核心研究计划，重点是陆地-水相互作用中的生态层面问题。在过去的六个野外季节里，SCWRS共支持了35个独立的访问研究项目，其中包括几个处理国家和全球重要生态问题的重大项目。 该项目是最近SCWRS物理设施扩建的直接结果，也是为了立即需要获得关键的分析设备，以支持当前和即将开展的研究活动。需要为三项主要采购提供支助：（1）用于测量水和固体中的磷、氮和二氧化硅的自动离子分析仪;（3）研究级立体和复合显微镜。 这些仪器将大大提高SCWRS测量水生系统生物和地球化学成分的分析能力。

The St. Croix Watershed Research Station (SCWRS) is the biological field station of the Science Museum of Minnesota (SMM). The lands and facilities of the SCWRS are located within St. Croix National Scenic Riverway at the boundary between Minnesota and Wisconsin. The SCWRS provides opportunities to conduct research on a large midcontinental river system and associated habitats. The SCWRS was established in 1989 and has greatly expanded its physical facilities, staffing, and research activity in the intervening six years. Following a strategic planning effort, a modern 6200 ft2 Research Center and year-round housing facility for visiting scientists were completed in 1995. In 1995-96 the SCWRS expanded its permanent research staff to create a core research program focusing on landscape-level problems in land-water interaction. A total of 35 separate visiting research programs have been supported at the SCWRS over the past six field seasons, including several major projects dealing ecological problems of national and global significance. This project is a direct outgrowth of the recent expansion of SCWRS physical facilities and the immediate need to acquire key pieces of analytical equipment to support current and pending research initiatives. Support is requested for three major acquisitions: (1) an automated ion analyzer for measuring phosphorus, nitrogen, and silica in water, and solids; and (3) research-grade stereo-and compound microscopes. These instruments will greatly improve SCWRS's analytical capabilities for measurement of biological and biogeochemical components of aquatic systems.
