Abstract

These data were collected in support of the sampling goals of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) Project. This study was conducted in the Talladega research watershed (outlet location: 33.76219799, -85.59550775) in the Talladega National Forest (Cleburne County, AL, USA). The watershed drains a non-perennial unnamed tributary of Pendergrass Creek, and contains 0.92 km^2 of mixed coniferous and deciduous forest in the Piedmont Upland physiographic section. Located near Anniston, AL, the watershed spans an elevation range from 345 to 456 m above sea level and is a tributary to the Coosa River (within the larger Mobile-Tombigbee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 5.3°C and 25.3°C respectively, and mean annual precipitation of 1,400 mm/yr. Between 7 October 2021 and 4 October 2024, we measured physicochemical parameters including water temperature (degrees Celsius), barometric pressure (mmHg), specific conductance (microSiemens per centimeter), dissolved oxygen, pH, and turbidity at the watershed outlet (TLM01) 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) using a YSI Pro1030 Waterproof Handheld meter. Readings were allowed to stabilize while water sampling took place. Data is not available when the site was dry - as noted by the flow_state column. In addition, some sampling events lacked a YSI handheld and data is therefore missing.
