C53A:
Advancing Understanding of Cold Climate Hydrologic and Geomorphic Systems in a Warming Climate I


Submit an Abstract to this Session


Session ID#: 60455

Session Description:
In cold settings, such as polar and alpine environments, the complex and nonlinear multi-phase behavior of water exerts a primary control on hydrology, geomorphology, vegetation, biogeochemistry, and associated ecosystem fluxes. As a result, liquid and frozen water availability is a key driver of periglacial Critical Zone architecture and processes such as surface and subsurface hydrological response, physical rock weathering, and sediment transport. As global mean air temperatures continue to increase, permafrost is expected to degrade, altering the availability of liquid and frozen water and hence hydrologic and geomorphic processes throughout cold regions. Despite the importance and rapidly changing nature of ground ice, surprisingly little is known about its occurrence such that processes related to ground ice melt are usually disregarded in modeling exercises. Novel remote sensing techniques, field-based investigations and experiments, and new model approaches aim to fill these gaps and inform critical zone processes in the cryosphere.
