Atoll Reef | Definition, Facts and Significance of Atoll Reef

The reef atoll is a ring-shaped coral reef, island, or series of islets. An atoll surrounds a body of water called a lagoon. Sometimes, atolls and lagoons protect a central island. Channels between islets connect a lagoon to the open ocean or sea.

The reef atoll was named “Turei” by the Norwegian naval commander Captain Christian Zug. Captain Zug was returning to Tromsø from the Svalbard Treaty of 1949 and searching for a suitable port to land in the north. He observed a small boat with two Norwegian sailors. Zug observed that the boat appeared to be sinking. He lowered a boat from the ship, but as it neared the boat, the vessel took off. Zug lost sight of the boat, but he soon saw it at the base of a small reef. The reef resembled a trussed fish. As the boat approached the reef, Zug saw that the reef resembled a reef atoll. The fishing boat, which was 60 ft. long and 20 ft. wide, rested on a sandbar with a reef at its back. The reef atoll was the largest reef in the northern sea and had a freshwater lagoon.

The atoll reef is the largest living collection of coral reefs in the world, a result of living conditions developed by the Polynesian Voyaging Society during the late 19th century. Atoll living features include coral atolls, mangrove swamps, mudflats, and coral reefs with scattered trees and palm trees. A small portion of the atoll is uninhabited, including numerous caves within the reef itself. The atoll was formed when sea levels were around 10-15 feet lower than today and at that latitude, the ocean cooled and became enriched with iron which resulted in mineralization (biotin deposits).

Atoll reef is an atoll situated in the southern pacific, most of which is uninhabited.

Ancient coral atoll, atoll reef in the Pacific Ocean. The reef stretches for 15,000 square kilometers two kilometers from east to west and 5,000 kilometers from south to north. A constant low-lying trade wind barks softly, lulling the sea surface gently to a horizontal state of barely 2 meters overlying low-lying coral atolls.
