An encircling coral reef or sandbar can create a shallower area of water near an island, called a lagoon.
A lagoon forms when a body of water is enclosed behind a barrier reef. It can also form together with the formation of an atoll, it being the body of water in the middle of the atoll. A lagoon is a body of comparatively shallow salt or brackish water separated from the deeper sea.
This is known as a lagoon, which is a shallow body of water separated from a larger body of water by a barrier such as a reef or sandbar. Lagoons can vary in size and can be found along coastlines all over the world.
An example of a submergent coastal area is a barrier island. Barrier islands are long, low-lying islands that form parallel to the mainland coast and are separated by a lagoon or bay. Over time, sea level rise can cause barrier islands to become submerged and eroded.
An atoll is a ring-shaped coral reef, island, or chain of islets surrounding a lagoon partially or completely. Atolls are typically found in warm, tropical oceans and seas, often in the Pacific and Indian Oceans.
A lagoon boundary is commonly referred to as a shoreline or edge where the lagoon meets the land.
A Barrier Reef. The barrier reefs grow parallel to the shore of an island and are separated from it by a deep lagoon.

Barrier reefs form parallel to the shoreline but are separated by a lagoon.
Barrier reefs form parallel to the shoreline but are separated by a lagoon.
A body of water separated from the ocean by a barrier island, reef system, or atoll. In the most generic sense, a lagoon is a small body of water separated from a large body of water by some physical boundary.
Each island is surrounded by a reef enclosing a shallow lagoon.

An island with a central lagoon is called an atoll. Kwajalein in the Indian Ocean is a very good example.
A shallow body of water that is separated from the open sea is called a lagoon. Lagoons are also commonly referred to as back reefs.
Poveglia Island is located in the lagoon of Venice, Italy.
