The lagoon (aka back reef zone) of a coral reef ecosystem is, for linear reefs (barrier and fringing reefs), that portion that lies between the reef crest and the shoreline. In the case of circular reef systems (atolls), it is centrally located.

Coral Reef Lagoon refers to the inner part of a coral reef where the coral sand is mainly composed of medium and fine sand particles. The lagoon area reflects a change in strength of hydrodynamics, with coral sand particles becoming finer …

2024年6月16日 · The combination of coral growth and water creates a lagoon. It may take as long as 300,000 years for an atoll formation to occur. Coastal lagoons form along gently sloping coasts. They are generally shallower than atoll lagoons and tend to be separated from the ocean by an island, reef, or sand bank.

Coral lagoons are restricted to tropical open seas that provide the conditions necessary for coral growth. They are best exemplified by the roughly circular quiet waters that are surrounded by warm-water coral atoll reefs.

Between the fringing reef and the land there is sometimes a small channel or lagoon. When the lagoon is wide and deep and the reef lies at some distance from the shore and rises from deep water it is called a barrier reef. An atoll is a reef in the form of a …

2023年10月19日 · Lagoons are shallow bodies of water separated from the ocean by sandbars, barrier islands, or coral reefs. The island of Bora Bora, part of French Polynesia in the South Pacific, is surrounded by a lagoon and a thick coral reef.

Coral reefs can be separated into three distinct zones: the back reef, reef crest, and fore-reef (Figure 7). The back reef includes the shallow lagoon between the shore and coral...

2024年12月24日 · lagoon, area of relatively shallow, quiet water situated in a coastal environment and having access to the sea but separated from the open marine conditions by a barrier. The barrier may be either a sandy or shingly wave-built feature (such as a sandbar or a barrier island), or it may be a coral reef.

A coral reef lagoon is that body of water that lies within an atoll (annular) reef or within a barrier reef. It is generally assumed that an appreciable depth of water is maintained within the lagoon, say 5-50 meters.

2024年6月16日 · This creates a lagoon of open, often deep water between the reef and the shore. Coral reefs are important because they bring in billions of dollars to our economy through tourism, protect coastal homes from storms, support promising medical treatments, and provide a home for millions of aquatic species.
