Alaska's Arctic coast has some of the highest erosion rates in the world. Erosion in the Arctic is primarily driven by permafrost melting and wave activity. The warming climate decreases sea ice coverage, resulting in an increase in wave energy. To overcome the lack of available observational w...

Alaska's Arctic coast has some of the highest erosion rates in the world. Erosion in the Arctic is primarily driven by permafrost melting and wave activity. The warming climate decreases sea ice coverage, resulting in an increase in wave energy. To overcome the lack of available observational wave data in the nearshore, waves were downscaled with a numerical wave model (SWAN) for the hindcast period of 1979-2019 utilizing several model domains along the coast. For each domain, the model was forced at the open boundary with 2000 representative sea states, which are likely combinations of significant wave heights, mean wave periods and mean wave directions in addition to wind speed and directions.
