American Geophysical Union Fall Meeting 2010 Permafrost-related sessions

C34. THE FATE AND LEGACY OF PERMAFROST: GEOCHEMICAL, GEOPHYSICAL, AND GEOMORPHIC ASPECTS

Landscapes underlain by permafrost reflect a legacy of climate history, and can be sensitive to climate change.  Predicting the effects of climate change on permafrost landscapes requires accurate characterization of geophysical controls on permafrost dynamics. This session seeks to combine diverse areas of permafrost geophysical study, from regional thermal monitoring networks to targeted process investigations, remote sensing, and modeling at diverse scales.  We welcome submission of work on thermokarst and active layer dynamics, geochemical indicators, and geomorphic evolution of permafrost landscapes, as well as paleoclimate studies incorporating preservation of ground ice morphologies through time.

H10. ECOHYDROLOGY OF ARCTIC AND SUB-ARCTIC ECOSYSTEMS: PATTERNS AND PROCESSES ACROSS SPATIAL AND TEMPORAL SCALES

In Arctic and sub-Arctic ecosystems, ecological and hydrological processes are tightly linked, but their interactions are often not well quantified. Also, the impact of permafrost on ecohydrology is not well understood. The ecohydrology of northern ecosystems is changing, with climate warming modifying already highly variable climate, permafrost, and vegetation. Understanding the ecohydrology of these systems is critical for quantifying atmospheric feedbacks and the response of hydrologic process to degrading permafrost terrain. We are interested in abstracts spanning multiple disciplines that explore ecohydrological questions of permafrost-affected terrain at different scales.
