Lagoon
This article is about natural lagoons. For other uses of lagoon, please see
Lagoon (disambiguation). A lagoon is a body of comparatively shallow
salt or
brackish water separated from the deeper
sea by a shallow or exposed
sandbank,
coral reef, or similar feature. Thus, the enclosed body of water behind a
barrier reef or
barrier islands or enclosed by an
atoll reef is called a lagoon. This application of lagoon in
English dates from 1769. It adapted and extended the sense of the Venetian laguna (cf Latin , 'empty space'), which specifically referred to
Venice's shallow, island-studded stretch of saltwater, protected from the
Adriatic by the
barrier beaches of the
Lido (see
Venetian Lagoon). Lagoon refers to both coastal lagoons formed by the build-up of sandbanks or reefs along shallow coastal waters, and the lagoons in atolls, formed by the growth of coral reefs on slowly sinking central islands. Lagoons that are fed by freshwater streams are also called
estuaries.
