Bao-Marchant high-resolution ion concentration and multiple stable isotope compositions from soils of the McMurdo Dry Valleys
Entry ID: Bao-Marchant_MDV_high-resolution_soil_ions

[ Update this Record ]

Summary
Abstract: The Bao-Marchant data set is a high-resolution (vertical) concentrations and
stable isotope compositions for water-soluble anions and cations form various
soils in the MDV. Each soil samples were taken from newly excavated soil pits
with the highest resolution physically attenable in the loosely packed soil
materials, ~ 2-10 cm each. The ions were water-leached from <2-mm ... View entire text
