Chenier

The name is derived from the French word for wood, “chêne,” meaning oak, which grows on chenier ridges within southwest Louisiana.

[3] The Louisiana Chenier Plain, extending roughly from Sabine Lake to Vermilion Bay along the Gulf Coast, serves critical ecosystem functions, particularly as a wildlife habitat and stopover for migrating birds.

Sediment fines are suspended and reworked aerially offshore, leaving behind lag deposits of mainly bivalve and gastropod shells separated out from the finer substrate beneath.

[5] In Essex, ground-truthing data demonstrate that the radar profiles accurately delineate the subsurface stratigraphy and sedimentary structure of the cheniers.

[6] An extensive complex of beach ridges and swamps (ritsen en zwampen in Suriname) was formed between the mouth of the Amazon River and the Orinoco on the coastal plain of the Guiana Shield.
