Alabama Barrier Island Restoration Study

Research - Sediment Characterization and Distribution

In order to aid in defining sedimentological gradients around the Alabama barrier island platform and surrounding water bodies, sediment samples were collected along shore-normal transects that incorporate the basal shoreface (seaward to depths that encompass the active transport zone during both fair-weather and storm conditions), middle shoreface, upper shoreface (mean low water; MLW), beach berm, dune, interior flats, washover platform, back-barrier marsh, back-barrier flats and other sub-tidal back-barrier environments along the entire extent of Dauphin Island as well as Sand/Pelican Island and Little Dauphin Island. These data are processed for water content, dry bulk density, percent organic matter, and textural characterization. This extensive dataset provides a foundation for restoration monitoring and planning, modeling coastal processes, and developing a better understanding of sediment-dispersal patterns around Dauphin Island. Specifically, these data can be used to:

Interpolated spatial distribution of median grain size
Interpolated spatial distribution of median grain size (in micrometer or microns) for the 300 plus samples collected on and around Dauphin Island, Alabama.
