Offshore Bar

the simplest coastal accumulative relief form, formed by the action of sweeping breakers. The bar has the form of a low ridge (bar), extending along the shoreline. Bars can reach hundreds of m or several km in length and 1–4 m in height; they are defined by the energy of the surf. Such bars are made of sand, gravel, pebbles, and shells. Ancient offshore bars are relicts of the old shoreline.
