AIMS Paint Rock Dissolved Gas Data (AIMS_SE_PRF_MIMS)

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.

This resource specifically includes the Membrane Inlet Mass Spectrometer (MIMS) dissolved gas seasonal (approach 2) sample dataset, including Argon (Ar), Oxygen (O2), Nitrogen (N2), N2:Ar ratio, and O2:Ar ratio. We collected seasonal MIMS samples at 7 sites throughout the Paint Rock watershed on six different occasions from March 13, 2022 to February 19, 2024.
