Arctic coastal processes
Convener: Zuzanna SwiradECSECS | Co-conveners: Gregor LuetzenburgECSECS, Anna M. IrrgangECSECS, Maria Ansine Jensen
Decreasing extent and duration of sea ice cover, changes in storm patterns as well as rising sea surface and air temperatures impact coastal processes in the Arctic. Wave overtopping, flooding and coastal erosion pose risks to societies and infrastructure located at the coast. There is a pressing need to understand the rates and mechanisms of coastal change to better predict future trajectories under the changing climate.
In this session, we invite contributions from a range of disciplines and across time scales on local to pan-Arctic studies related to coastal processes in the Arctic. Those can include observational (satellite and instrumental) data, historical data, geological records and proxy data, model simulations as well as forecasts, for the past, present and future rates and drivers of Arctic coastal change. The common denominator of these studies will be their focus on a better understanding of short- to long-term mechanisms and feedbacks that drive Arctic coastal changes, and their impact on coastal communities and infrastructure, at local to global scales.
Submissions can include but are not limited to studies investigating nearshore wave dynamics, the role of sea ice, changing precipitation patterns, sea surface and air temperature development, thawing permafrost, surf and swash zone dynamics, and wave energy dissipation caused by the presence of ice on the shore. We also welcome studies on the application of new technologies (e.g. radar, UAVs, machine learning) for coastal mapping and change detection. Moreover, we are interested in observations of weathering processes (e.g. freeze-thaw cycles, chemical weathering), modelling coastal morphodynamics including laboratory and field experiments as well as exploratory numerical simulations, and risk assessment for coastal settlements and infrastructure.
