Description
Summary:This excel workbook contains sheets with data obtained from soil pore water samples collected in a tundra hillslope draining into Imnavait Creek, a a headwater catchment in Arctic Alaska. We installed three replicated lysimeter arrays in representative hillslope and riparian landscape positions. At the top of each lysimeter array we applied potassium bromide to trace preferential flow paths and exchange potentials between organic and mineral soil horizons in hillslope and riparian positions. At each array, lysimeters O1, O2, and O3 were installed in the organic horizon, approximately 12 cm deep, and lysimeters M1, M2, and M3 were installed at the mineral-permafrost interface, approximately 50 cm deep (shown in blue). Lysimeters O3 and M3 were installed on a 45° angle from the site of bromide application to estimate horizontal flows across the landscape. The first sheet contains metadata and site information, the second sheet contains spatial information for each lysimeter, the third sheet provides pore water chemistry results, including concentrations of carbon, nitrogen, and phosphorus, fluorescence and 1H-NMR indices. The fourth sheet contains results from the bromide tracers, and the fifth sheet contains raw 1H-NMR data.
