Paint Rock Environmental Data (AIMS_SE_PRF_ENVI)

This resource includes static environmental data collected for the sensor and sampling locations in the Paint Rock research watershed (outlet location: 34.96861724,  -86.16501705) on privately owned property in Jackson County (AL, USA) as part of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) project, an NSF EPSCoR funded project (OIA 2019603). The project sought to explore the impacts of stream drying on downstream water quality across Kansas, Oklahoma, Alabama, and Idaho, integrating datasets on hydrology, microbiomes, macroinvertebrates, and biogeochemistry. The watershed drains a non-perennial unnamed tributary to Burks Creek, and contains 2.97 km^2 of deciduous forest in the Cumberland Plateau physiographic section. Located near Estillfork, AL, the watershed spans an elevation range from 211 to 550 m above sea level, and is a tributary to the Paint Rock River (within the larger Tennessee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 4.4°C and 25.4°C respectively, and mean annual precipitation of 1,390 mm/yr.

All data was extracted from Digital Elevation Model (DEM) rasters provided by the USGS National Map Downloader v2.0. Additionally, accompanying watershed_PRF.zip and streamnetwork_PRF.zip files contain .shp files containing the watershed boundary polygon and delineated stream network lines respectively. The watershed was delineated to the outlet location (site: PRM01), and the stream network was delineated using a threshold of 60,000 cells to most closely match the field-observed geomorphic stream network.
