Druhan and Matthew J. Winnick A three-dimensional rendering of a hillslope (using a colorized LiDAR point cloud) combined with a reactive transport model simulation of oxygenated water infiltrating through heterogeneous regolith. The oxygen distribution is controlled by biological consumption, inorganic redox reactions, and regolith porosity/permeability. The color scale reflects the log of the aqueous oxygen concentrations (yellow = high; blue = low). IllustratIon by Kate Maher, ulI Mayer and dana ChadwICK
