C21C:
Where, When, and Why Will Arctic Landscapes Get Wetter or Drier? Posters
Session ID#: 8782
Session Description:
Arctic landscapes are characterized by large expanses of saturated soils, wetlands, ice wedge polygon ponds and thermokarst ponds and lakes. The spatial and temporal dynamics of soil saturation and inundation drive ecosystem responses, carbon and water cycles and the energy balance. Earth System Models predict an overall drying of Arctic soils by the end of the 21st century, but are not yet able to represent the spatial and temporal heterogeneity in increasing and decreasing lake, pond and wetland area observed over recent decades. We invite abstracts that explore observations and models to quantify and predict: 1) the spatial and temporal patterns of changes in soil moisture and inundation, and 2) the underlying controls (climate, landscape structure, permafrost properties, ecosystem interactions, etc.) on shifts in landscape wetness. This session aims to highlight a framework for improving our ability to predict where, when and why Arctic landscapes will become wetter or drier.
