2017 AGU Session: Geophysical characterization of coupled cold regions hydrology and permafrost dynamics
We are pleased to announce the following session on geophysics in permafrost at AGU 2017 New Orleans and we hope
that you will consider submitting an abstract.
Geophysical characterization of coupled cold regions hydrology and permafrost dynamics [ID#22537]
The cold regions of Earth are changing, with significant impacts on landscape-scale hydrological processes. Surface and airborne geophysical methods are increasingly used to observe these changes because of the
contrasts in geophysical properties that exist between frozen and thawed ground, or between solid-ice features and liquid water. In permafrost regions, geophysical methods also offer insight into groundwater flow, surface-water/groundwater exchange dynamics,
and post-fire changes to the hydrologic system. This session is open to ground or airborne geophysical studies that focus on scientific objectives such as the detection and delineation of ground ice or permafrost, evaluating sub- and suprapermafrost water
flow, thermokarst evolution, and monitoring active layer dynamics. We will consider field-measured or modeled seismic, resistivity, ground-penetrating radar, gravity, magnetics, and other electromagnetic studies at any spatial scale. We also encourage multidisciplinary
projects that incorporate geophysics with the impacts of frozen material change on cold-regions ecology and/or biochemistry.
