Detailed Description
Examples of sediment dynamics offshore of barrier islands include the development and erosion of shoals, tidal deltas, and sand ridges. The perspective block diagrams above show elevations for a portion of the seafloor adjacent to Dauphin Island, Alabama (top left), measurement of accretion and erosion of these features (top right) reveal their dynamic nature over the past half-century. Data source and analysis from DeWitt and others (2018) and Flocks and others (2017).
