Sublittoral coarse sediment in variable salinity (estuaries)

English name: Sublittoral coarse sediment in variable salinity (estuaries)

Description (English)

Clean gravels that occur in the upper reaches of marine inlets, especially estuaries, where water movement is sufficiently strong to remove the silt content of the sediment. The habitat typically lacks a significant seaweed component and is characterised by a sparse but very robust brackish-water tolerant fauna.
