“…When Islands associated with the coral and mud-based Florida Keys Physiographic Realm archipelago are classified as the predominant geoform, the resultant landforms include Bay Key, Karst Island, and Salina (Finkl, 2004;Hoffmeister, 1974;Lidz et al, 1997;Nunn, 1994). Sediment Flat Geoforms, which constitute extensive, unconsolidated seafloor sediments composed of sand and mud combinations, are divided among the landforms of Intertidal Sand Flat and Planar Bed Forms and Ripples (Davis, Hine, and Shinn, 1992;Duane and Meisburger, 1969;Finkl, 2004;Finkl and Andrews, 2008;Finkl and Warner, 2005;Finkl, Benedet, and Andrews, 2005b;Finkl et al, 2008;Hoffmeister, 1974;Lidz, Robbin, and Shinn, 1985). The geoform of Dune and Beach is a geomorphologically coupled coastal system consisting of Holocene dune fields, foredunes, and beach berms.…”
