AGU 2018: The Role of Ground Ice in Permafrost Hydrology and Geomorphology (C041)

Moritz Langer

Dear permafrost and polar research enthusiasts,

this is another advertisement for an AGU session on:

The Role of Ground Ice in Permafrost Hydrology and Geomorphology (C041)

Ground ice content strongly determines the sensitivity of permafrost processes and Arctic ecosystem functions to a warming climate. Ground ice can impede the propagation of warming into permafrost, but once ice melts a wide range of morphodynamic and erosional processes are triggered. These processes lead to lasting and often irreversible changes in topography, hydrology, vegetation, biogeochemistry, and the associated ecosystem fluxes. Despite the importance of ground ice, surprisingly little is known about its occurrence and spatial variability. Furthermore, processes related ground ice melt are usually disregarded in modeling exercises leaving large uncertainties in current climate impact studies. However, novel remote sensing techniques, field-based investigations and experiments, and new model approaches aim to fill this gap. We invite studies that use in situ experiments and observations, remote sensing data, models, or combination thereof, to gain a better understanding of ground ice and its role in permafrost hydrology and geomorphology.

Abstract Submission Deadline: 1 August 2018, 11:59 PM EDT

This session is chaired by Cathy Wilson (Los Alamos National Lab), Sebastian Westermann (University of Oslo), and me (Alfred Wegener Institute).
We are looking forward to meet you in Washington, D.C.

Best wishes
