Lake Water System, Boat Dry Dock, and Replacement of Obsolete Instruments at the Flathead Lake Biological Station

9311705，PI-斯坦福大学：成立于1899年，平头湖生物站（FLBS）有着悠久的实地教育和研究传统，重点是湖沼学。 FLBS有15名工作人员和70万美元的年度预算（50%校外）。 自1983年以来，国家已投资200多万美元用于新住房、实验室和设备。 1992财政年度增加了两个教授职位和技术支助职位（数据管理员和业务助理主任）。 最近的研究已经解决了地下水生态（1987 - 90）和食物网的贫营养湖泊（1990 - 93）已被添加到站阵列的设施。 合作研究涉及来自世界各地的访问调查人员，并涵盖湖沼学的许多方面，从生物体水平的物候学和溪流生物群的遗传学工作到大型湖泊和河流洪泛区物质通量的生态系统水平检查。 为了提高研究能力，该项目将改造和改善Elrod实验室的湖泊和溪流供水系统。 目前的方法是从平头湖的上层水层和下层水层供水，并从站地面上的泉水，以提供一系列的来源，温度和食物供应的生物群局限在实验室的微观世界在现有的湿室。 还需要新的仪器（CHNS分析仪、闪烁计数器、2个研究显微镜、离子色谱仪、现场荧光计），以取代过时的仪器。 这些项目需要长期湖沼学数据库的延续和多调查员研究的增长。

9311705, PI-Stanford: Established in 1899, the Flathead Lake Biological Station (FLBS) has a long tradition of field based education and research, with emphasis in limnology. FLBS has a 15 member staff and an annual budget of $700,000 (50% extramural). Since 1983, over $2 million has been invested by the State in new housing, labs and equipment. Two professorships and technical support positions (Data Manager and Assistant Director for Operations) were added in fiscal year 1992. Recent research has addressed on groundwater ecology (1987 90) and food webs of oligotrophic lakes (1990 93) have been added to the stations array of facilities. Collaborative studies involv e visiting investigators from around the world and encompass many aspects of limnology, from organism level work on the phenology and genetics of stream biota to ecosystem level examinations of materials flux in large lakes and river floodplains. To enhance research capability, this project will retrofit and improve the lake and stream water delivery system to the Elrod Laboratory. The present approach is to supply water from the epilimnion and hypolimnion of Flathead Lake, and from a springbrook on the Station grounds, in order to provide an array of sources, temperatures and food supplies to biota confined in laboratory microcosms within existing wet rooms. Also requested is new instrumentation (CHNS analyzer, scintillation counter, 2 research microscopes, ion chromatograph, field fluorometer) to replace outdated units. These items are required for continuation of long term limnological data bases and growth of multi investigator research.
