Terrestrial laser scanner measurements, linearly interpolated on grid, at the beach in Oysterville, Washington State, United States. Study is carried out within the scope of Sandbar-aEolian-Dune EXchange Experiment (SEDEX²). SEDEX² is a 6 week field campaign conducted in the summer of 2016 with the aim to improve the understanding of beach-dune dynamics by testing the hypothesis that sediment supply to the backshore beach and dunes is dominated by the welding of intertidal sandbars to the shoreline.
