Recent reports have showed increasing rates of coastline erosion locally in the Arctic. Paleoclimate evidence suggests that past episodes of varying ground temperatures, more or less sea ice, and changes in sea surface height were important in the past. Driving factors for Arctic coastal geomorphodynamics can be atmospheric, oceanographic or relate to the landscape history on the terrestrial side of the coastline. Understanding the interactions between thermal, geotechnical, hydrodynamic, and sea ice processes is critical for successful modelling and projection of coastal change in this environment. Contributions to this session include papers on the interactions between environmental forcing factors and the land and ocean in the Arctic coastal zone. Approaches may include process monitoring, long-term data records, and modelling techniques.
