  • Electrical Resistivity Tomography Inverted Models; Alaska, 2015

    Metadata Updated: March 22, 2021

    Fire can be a significant driver of permafrost change in boreal landscapes, altering the availability of soil carbon and nutrients that have important implications for future climate and ecological succession. However, not all landscapes are equally susceptible to fire-induced change. As fire frequency is expected to increase in the high latitudes, methods to understand the vulnerability and resilience of different landscapes to permafrost degradation are needed. Geophysical and other field observations reveal details of both near-surface (less than 1 m) and deeper (greater than 1 m) impacts of fire on permafrost along 14 transects that span burned-unburned boundaries in different landscape settings within interior Alaska. Electrical resistivity tomography (ERT) data collected along the 14 transect were used to map the spatial distribution of permafrost across burned-unburned boundaries.
