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 
We are looking forward to meet you in Washington, D.C.

Best wishes
