30th Nordic Geological Winter Meeting: Session on Permafrost and Periglacial Processes

Ivar Berthling
Dear Colleagues,
 
We would like to draw your attention to the Permafrost and Periglacial Processes session at Nordic Geological Winter Meeting in Reykjavik, 9th to 12th of January, 2012 http://www.jfi.is/ngw_2012:
 
Conveners: Ivar Berthling and Bernd Etzelmüller
 
Description: Permafrost is common in all Nordic mountain areas and a dominant characteristic of ground conditions in adjacent High-Arctic areas. The presence of cryotic ground conditions has important implications across the Earth and Planetary sciences including engineering. Permafrost aggradation or degradation takes place due to complex interactions between the surface-atmosphere energy exchange, (seasonally variable) ground surface and sub-surface thermal characteristics, and geothermal heat flow. The effect of climate change on permafrost distribution is likely to be pronounced, but there is strong heterogeneity in time and space of permafrost response due to these interactions. There is therefore a need for better models of transient ground thermal conditions, also for addressing  and quantifying the positive feedback effects to climate change because of potentially increased greenhouse gas (GHG) release due to  permafrost thaw. Permafrost and seasonal frost govern a.o. periglacial processes, such as periglacial slope processes, rock glacier development, interaction with glacial processes and mass wasting.  These processes have faced increased attention, e.g. in relation to frozen and thawing slope stability, rock glacier distribution as an indicator of paleoclimate, and the role of ground thermal regime in landscape dynamics. The session will therefore invite for presentations addressing mapping, monitoring and modelling permafrost, along with studies related to periglacial processes and landforms.
 
Deadline for abstract submission is 1st of October 2011: http://www.jfi.is/ngw_2012/submit-abstract
 
 
Please don't hesitate to contact us should you have any questions about 
this session.
