Many sandy shorelines include sand ridges attached to the shoreface. To explain the evolution and dynamics of shoreface-connected ridges, Son et al. describe observations of sedimentary structures, sediment textures and bathymetry from repeat surveys over the same area in the southern North Sea, and characterize changes in the context of observations and models of tides and waves. The data reveal variability and systematic changes, interpreted to be the result of a combination of tides and waves generated by storms. These data lead to a conceptual model for the variable and dynamic sedimentology and morphology of these ridge-and-trough systems, and their possible ultimate stratigraphic record.
