Collaborative Research: Integrated Geophysical And Hydrogeologic Study Of A Large Maine Peatland, Andrew S. Reeve

University of Maine Office of Research Administration: Grant Reports

Solute transport controls vegetation and water chemistry gradients in peatlands. Dispersive mixing and advective transport in peat will be measured in laboratory column experiments and in a natural gradient tracer test in a peatland to determine the relative importance of these processes. We will assess the retardation of solutes by matrix diffusion and the applicability of a dual-domain model. Electrical geophysical methods, verified through direct measurements, will be used to track tracer migration.

An extensive geophysical and hydrogeologic characterization of the peatland will map variability in peat depth across the basin and identify stratigraphy. Ground-penetrating radar and resistivity/induced polarization imaging …
