Ron Sletten studies chemical and physical processes in surficial deposits including how they are influenced by biological processes. His primary interest is in permafrost-influenced soil and has worked extensively in Alaska, High Arctic field sites (Svalbard, Devon Island, Greenland) and the Dry Valleys, Antarctica. His active research includes carbon cycling in Greenland soils; ground ice and surface stability of the Dry Valleys; and diffusion in frozen porous media.
Sletten also conducts research on diverse topics in soil and water chemistry including natural organic matter, heavy metals; and diffusion of water in frozen soils. His laboratory includes an ICP-OES, ICP-MS, laser diffraction particle size, carbon analyzer. He develops instruments for automatic monitoring of soil processes using data loggers and ground water sampling equipment.
