There will be an OPEN SESSION ON PERMAFROST (CR20) at the EGU General
Assembly in Vienna, Austria, 15 - 20 April 2007.
Deadline for abstract submission is 15 Jan 2007.
SESSION DESCRIPTION AND CALL FOR PRESENTATIONS:
Permafrost is a widespread phenomenon in polar areas and cold mountain
terrain. Geomorphic processes that are associated with permafrost have
also had a strong influence on the morphogenesis of vast areas in the
mid latitudes during the Pleistocene. In the light of present and likely
future climate changes, permafrost environments are expected to undergo
rapid changes. Alterations in the thermal regime may cause geotechnical
and environmental problems, mainly in terms of thaw subsidence,
increased frequencies of rapid mass movement and severe changes of soil
moisture contents and water balance. Permafrost research can thus
contribute to the understanding of present and past periglacial
processes and landforms, help to obtain valuable information from e.g.
geomorphology or monitoring networks and provide the basis for
simulations of possible future developments within this fragile
environment. In this session we invite contributions about permafrost
and related topics that come from all disciplines, backgrounds, applied
methodologies and geographic areas and that do not explicitly belong to
any of the other specialized sessions.
I cordially invite you to participate and look forward to seeing you
and your presentations in Vienna.
