This dataset includes raw point cloud data from repeat terrestrial laser scans (TLS) for measuring saltation and moisture dynamics as well as early-stage protodunes developing on a moist beach surface. As well as the TLS data, additional measurements include wind speed with a CSAT 3D sonic anemometer and sediment transport using a Sensit and Wenglor fork sensors. Sediment traps were also used for sediment transport, and grain size of the trapped sand was measured.
