Role of atmospheric indices in describing shoreline variability along the Atlantic coast of Europe
Beaches are highly variable environments and respond to changes in wave forcing, themselves modulated by climate variability. Here, we analyse three high-quality beach profile datasets to robustly investigate, for the first time, the link between shoreline change, wave forcing and climate variabilit...
