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.

Samples were filtered with a 0.45um PES filter and frozen until analysis. Aqueous concentrations of anions were determined using an IC-3000 IC system (Dionex, Sunnyvale, CA) equipped with Dionex AERS 500 suppressor (2 mm, Thermo Scientific) and Dionex AS auto-sampler (Thermo Scientific). A Dionex IonPac AS15 column (2 mm × 50 mm, Thermo Scientific) with a guard column Dionex IonPac AG15 (2 mm × 50 mm, Thermo Scientific) was used to separate anions using a mobile phase of 38 mM KOH and a flow rate of 0.3 mL/min. The column temperature is 30 °C. Chromeleon software 7.1 is used for system control. Final data tab shows average of triplicates collected in the field and st dev of triplicates. Any NO3 values below 0.01 mg/L are below the lowest standard used in lab analysis and should be interpreted with caution.
