Stream Temperature - Tarleton (TLTN) Water year 2007-2008

Metadata for BES site - Stream Temperature: Tarleton (TLTN): 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 Tarleton located in Carney, Maryland off Tarleton, Lane. The watershed area is 10ha and has no forest cover with 42% impervious. Watershed information was taken from delineations created with USGS StreamStats at http://water.usgs.gov/osw/streamstats/maryland.html Purpose: Long-term monitoring of stream temperature in a suburban watershed.

BES站点——溪流温度元数据：塔尔顿（TLTN）：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计划，Baltimore Ecosystem Study，简称BES）中，我们采用流域方法开展综合生态系统功能评估。该LTER研究以格温斯福尔斯流域为核心研究区，该集水区面积达17150公顷，覆盖从巴尔的摩城市核心区，经1900-1950年建成的老旧城市居住区、1950-1980年建成的郊区地带、快速郊区化区域，直至乡村/郊区边缘的完整环境梯度。研究团队在整个格温斯福尔斯流域以及巴尔的摩县/市周边的补充监测站点中，持续开展溪流温度监测。总计有22个站点配备了HOBO Pro v2型水温数据记录仪（型号U22-001），每2分钟采集一次瞬时温度读数，数据每月批量下载一次。本数据集对应位于马里兰州卡尼市塔尔顿巷沿线的塔尔顿监测站点，该站点所在流域面积为10公顷，无森林植被覆盖，不透水面占比达42%。流域边界信息源自美国地质调查局（United States Geological Survey，简称USGS）StreamStats工具生成的流域划分结果，查询网址为http://water.usgs.gov/osw/streamstats/maryland.html。本数据集的应用目的为对郊区流域的溪流温度开展长期监测。主题关键词包括：溪流、流域、温度、郊区、巴尔的摩生态研究计划。坐标信息：纬度/经度为39.4054（39°24′19″），-76.5385（-76°32′19″）。
