Arctic Coastal Dynamics: Rates, Impacts, Hazards and Implications for the Future
Session ID#: 161058
Session Description:
Arctic coastlines are highly vulnerable to anthropogenic and climate-driven changes. Coastal hazards like erosion and flooding are intensifying and creating risks for coastal communities. The goal of this session is to create a platform for discussing recent research on the changes in Arctic coastal dynamics, resulting hazards and risks, and advances in modelling. We invite studies that cover topics related to Arctic coastal changes, the driving forces, geomorphological processes, modelling approaches and impacts on ecosystem ecology, biogeochemistry, infrastructure, and social systems. Further, we discuss the co-production of knowledge and tools for forecasting coastal hazards and risks to quantify their social and economic impacts. We welcome abstracts on cross-disciplinary studies at the nexus of 1) environmental variables that influence nearshore hydrological, geomorphological, ecological, and biogeochemical processes; 2) variability in coastal change and key driving forces; 3) collaborative approaches from communities, researchers and agencies to develop monitoring programs to support hazard forecasting.
