Session Description: Frozen ground, which underlies half of the exposed land surface in the Northern Hemisphere, is found extensively at high latitudes and intermittently at high elevations at lower latitudes. In these cold regions, frozen ground exerts a primary control on the timing and distribution of surface and subsurface water flow and storage. As global air temperatures increase, frozen ground is expected to degrade, altering hydrologic conditions through changes in soil moisture, groundwater-surface water interactions, streamflow seasonality, and surface water body connectivity. This session welcomes studies across the disciplines of hydrology, global environmental change, and the cryosphere that explore ongoing changes to the hydrology and hydrogeology of cold regions. These include, but are not limited to, studies that utilize field observations, remote sensing datasets, geophysical techniques, and numerical modeling. We particularly encourage presentations that highlight cold region groundwater-surface water interactions as well as hydrologic and ecologic consequences of frozen ground thaw.
