Stream Temperature - Powder Mill Run (PDML) Water year 2006-2007

Metadata for BES site - Stream Temperature: Powder Mill Run (PDML): 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 Powder Mill Run near Lochearn, MD. The site drains roughly 943 acres of old suburban and urban land.
