My fieldwork includes a slew of hydrologic (hydraulic head, precipitation, air temperature, solar radiation, snow disappearance date, ect.), biogeochemical (porewater chemistry, carbon flux, plant metrics etc.), and spatial (surface topography, depth to permafrost, kinematic GPS surveys, ect.) data. These data are paired with soil temperature data from the surface into permafrost. I have two sites in Alaska. The first site, located in Interior Alaska, will allow for measurements under current sub-arctic climate conditions, while the second site, located on the warmer and wetter Kenai Peninsula, will allow for measurements under projected future sub-arctic climate conditions. The fieldwork portion of the study will last three years, with one season already completed.
