Data Acquisition and Management System for Flathead Lake Biological Station

弗拉黑德湖生物站（FLBS）成立于1896年，有着悠久的实地教育和研究传统。1980年开始重视湖沼学。FLBS现在有15名员工，年度预算为70万美元（60%来自校外）。另外还有200万美元投资于新住房和淡水研究实验室。美国国家科学基金会资助了一艘30英尺的研究船（1987- 1988），并资助了对低营养化河流（1987- 1990）和低营养化湖泊食物网（1990- 1992）的研究。FLBS的研究和监测（例如，日排放量和温度；化学变量和生物群）已为平头河流域22241平方公里的50多个地点建立了长期数据库。例如，平头湖的湖泊和水文资料可以追溯到1902年。由于这些数据库对于研究平头河湖生态系统的结构和功能至关重要，因此将围绕长期研究目标开发数据档案和管理，以增强连续数据获取能力。将购置一个计算机系统，用于数据库管理、一个湖中浮标和平头湖气象站、全球定位系统（GPS）和自动水柱分析系统（即连续的GPS、CDT、传输计和声纳数据，记录在便携式计算机上，供科考船输入现有的地理信息系统）。这些设备与现有的数据记录仪、传感器和采样器一起构成了数据库系统的硬件。将雇用一名全职人员来协调日常数据采集和管理FLBS数据库，以供研究使用和满足访问调查人员的需要。

Established in 1896, the Flathead Lake Biological Station (FLBS) has a long tradition of field-based education and research. In 1980, emphasis on limnology was initiated. FLBS now has a 15-member staff and an annual budget of $700,00 (60% extramural). An additional $2 million has been invested in new housing and a Freshwater Research Lab. NSF awards have provided a 30` research vessel (1987-88) and research on stream hyporheos (1987-90) and food webs of oligotrophic lakes (1990-92). FLBS research and monitoring (e.g., daily discharge and temperature; chemical variables and biota) has generated long-term data bases for over 50 sites in the 22,241 km2 Flathead River Basin. For example, limnological and hyrological data for Flathead Lake date to 1902. Because these data bases are essential to research on the structure and function of the Flathead River-Lake Ecosystem, a data archival and management will be developed and enhance continuous data acquisition capability around long-term research objectives. A computer system for data base management, a midlake buoy and weather station for Flathead Lake and global positioning (GPS) and automated water column profiling systems (i.e., continuous GPS, CDT, transmissometer and sonar data logged on a portable computer for input to existing GIS for the research vessel are to be acquired. These items, coupled with existing data loggers, sensors and samplers, compose the hardware of the data base system. A full-time person will be employed to coordinate routine data acquisition and to manage FLBS data bases for research use and for the needs of visiting investigators.
