This resource contains high-frequency EXOS water quality sensor data collected at the outlet of the Talladega study watershed, including conductivity, dissolved oxygen, turbidity, fluorescent dissolved organic matter concentrations, and temperature. This study was conducted in the Shambley Creek research watershed (outlet location: 32.98410915, -88.01334337) on privately owned property in Greene County (AL, USA). The watershed drains a non-perennial unnamed tributary to Shambley Creek, and contains 0.70 km^2 of coniferous forest managed for silviculture in the East Gulf Coastal Plain physiographic section. Located near Eutaw, AL, the watershed spans an elevation range from 63 to 94 m above sea level, and is a tributary to the Sipsey River (within the larger Mobile-Tombigbee basin). The region has a humid subtropical climate, with mean daily January and July air temperatures of 7.3°C and 27.4°C respectively, and mean annual precipitation of 1,350 mm/yr.

These data were collected in support of the core sampling goals of the Aquatic Intermittency effects on Microbiomes in Streams (AIMS) Project. Between 1 August 2021 and 1 August 2024, we monitored surface water quality and physicochemistry at the outlet (WHM01) of the AIMS Shambley Creek watershed at 15 minute intervals using a multi-parameter sonde (YSI EXO2).
