This example of a subtropical tidal sand flat (25°55′12″S, 113°56′59″E) separates Shark Bay from Hamlin Pool on the central west coast of Western Australia. The land area in the upper left-hand corner of the image is Faure Island with the sandy area of Pelican Island opposite. These sandy tidal flats separate the hypersaline Hamlin Pool to the south from Shark Bay to the north, which in turn connects with the eastern Indian Ocean. The simplified tri-sequent catena of archetypes forms the Dominant Catenary Sequence (DCS) Flat-Beach-Upland (F-Be-U), which is expanded in the Coastal Ecological Sequence (CES) to 7F_sa,sv,tcBe_ca,siU_sr that defines the coastal belt as containing calcareous sandbanks, submerged vegetation, and tidal channels backed by a mixed carbonate-silicate beach grading to upland scrub vegetation. The complete CBLC codification works out to (LME44)7F_sa,sv,tcBe_ca,siU_sr(ER207) by incorporating the West-Central Australian Shelf Large Marine Ecosystem and the Carnarvon Xeric Shrublands Ecoregion.
