Abstract
This study was conducted in the Paint Rock research watershed (outlet location: 34.96861724, -86.16501705) on privately owned property in Jackson County (AL, USA). 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. These samples were collected in support of the core sampling goals of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) Project. Between 13 October 2021 and 27 June 2024, grab samples for Dissolved Organic Carbon concentration (DOC, mg/L) collected at the watershed outlet (PRM01) every 3 weeks during routine sensor maintenance (AIMS Approach 1), seasonally at seven distributed, long term monitoring sites (AIMS Approach 2), and during a large synoptic sampling efforts concentrated across the watershed (AIMS Approach 3). DOC samples were filtered through pre-ashed, 0.7-micron glass fiber filters (Whatman GF/F) into acid-washed, 60-mL amber high-density polyethylene (HDPE) bottles. DOC samples were preserved by acidifying to a ph = 2 using concentrated HCl and refrigerated until analysis within 28 days of collection. DOC concentrations were determined as non-purgeable organic carbon (NPOC) using a total organic carbon analyzer (Schimadzu TOC-V).
