Stream Temperature - Gwynns Falls at Villa Nova (GFVN) Water year 2007-2008

Metadata for BES site - Stream Temperature: Gwynns Falls at Villa Nova (GFVN): In the Baltimore urban long-term ecological research (LTER) project, (Baltimore Ecosystem Study, BES) we use the watershed approach to evaluate integrated ecosystem function. The LTER research is centered on the Gwynns Falls watershed, a 17,150 ha catchment that traverses a gradient from the urban core of Baltimore, through older urban residential (1900 - 1950) and suburban (1950- 1980) zones, rapidly suburbanizing areas and a rural/suburban fringe. Stream temperature is continuously measured throughout the Gwynns Falls watershed along with supplemental sites around Baltimore County/City. A total of 22 sites contain sensors (HOBO Pro v2 Water Temperature Data Logger - U22-001) that take an instantaneous temperature reading every 2 minutes. These data are downloaded on a monthly basis. This dataset is for the Gwynns Falls at Villa Nova. This site samples drainage from approximately 7,400 ha of old and new suburban and suburbanzing land use. Streamflow at this station has been monitored continuously by the USGS since 1957 (with a hiatus from 1988 - 1995). This station is the boundary between the urban and suburban portions of the Gwynns Falls. A detailed description of this site is posted at: http://md.water.usgs.gov/BES/01589300/. Streamflow data for this site are posted at: http://waterdata.usgs.gov/md/nwis/nwisman?site_no=01589300 Purpose: Long-term monitoring of stream temperature in a watershed.

BES站点元数据——溪流温度：维拉诺瓦处的格温斯瀑布（Gwynns Falls at Villa Nova, 简称GFVN）：在巴尔的摩城市长期生态研究（Long-term Ecological Research, 简称LTER）项目——即巴尔的摩生态研究（Baltimore Ecosystem Study, 简称BES）——中，我们采用流域方法评估综合生态系统功能。
该LTER研究以格温斯瀑布流域为核心，这是一片面积达17150公顷的集水区，其土地利用梯度覆盖巴尔的摩城市核心区、1900-1950年建成的老旧城市居住区、1950-1980年建成的郊区、快速郊区化区域以及城乡结合部地带。
格温斯瀑布流域内及巴尔的摩县/市周边的补充监测站点均持续监测溪流温度。
总计22个站点部署了HOBO Pro v2水温数据记录仪（U22-001），该设备每2分钟采集一次瞬时温度读数，数据按月进行下载。
本数据集对应维拉诺瓦处的格温斯瀑布站点，该站点的汇水区域涵盖约7400公顷的新旧郊区及郊区化土地利用类型。
该站点的径流监测自1957年起由美国地质调查局（United States Geological Survey, 简称USGS）持续开展，仅在1988年至1995年间存在监测中断。
该站点是格温斯瀑布流域城市片区与郊区片区的分界线。

该站点的径流数据可查阅：http://waterdata.usgs.gov/md/nwis/nwisman?site_no=01589300
数据集用途：对流域内溪流温度开展长期监测。
