NS21A:
Applications of Near Surface Geophysics in Periglacial Regions Posters


Session ID#: 8362

Session Description:
Throughout the world, permafrost, sea ice, and glaciers are changing, with significant impacts on the surrounding ecosystem, environment, and society. Surface and airborne geophysical methods are increasingly used to monitor these changes because of the strong contrasts in geophysical properties that exist between frozen and thawed ground, or between solid-ice features and liquid water. Geophysical methods also offer insight into groundwater flow and surface-water/groundwater exchange dynamics. This session is open to ground or airborne-platform geophysical studies, focused on scientific objectives such as detecting and monitoring glacier change; detection and delineation of ground ice or permafrost; and monitoring the thickness and extent of sea ice.  The session will consider seismic, resistivity, ground-penetrating radar, gravity, magnetics, and other electromagnetic studies over a variety of spatial scales.  We also encourage the submission of multidisciplinary projects that incorporate the impacts of frozen material change on cold-regions ecology and/or biochemistry.
