EP23D:
The Past, Present, and Future of Arctic Coastal Change Posters


Submit an Abstract to this Session


Session ID#: 45242

Session Description:
Arctic coasts are increasingly vulnerable to coastal erosion, storm-surge flooding, sea-level rise, infrastructure damage, and potential oil spills. This leads to negative impacts on wildlife habitat, subsistence hunting grounds, coastal communities, and those dependent on infrastructure at risk. The threats are likely to intensify in the future as temperatures warm and declining sea-ice extent leaves coastlines exposed for longer periods of time. A better understanding of coastal processes, rates, and geographic variability is needed to assess the vulnerability of Arctic coasts and accurately project future change. We invite contributions from studies that improve our knowledge of Arctic coastal dynamics through remote sensing, time-series analysis, field surveys, and modelling. This includes studies that inform our baseline understanding of Arctic coastal systems or focus on new technologies and method development. We also welcome studies which demonstrate linkages to climate change, sea-ice decline, coastal hazards, ecosystem management, infrastructure risk, and oil-spill response.
