The same storm also created a reef barrier at the Atlantic Ocean.

Accepted as basically correct, his explanation involved considering that several tropical island types — from high volcanic island, through barrier reef island, to atoll — represented a sequence of gradual subsidence of what started as an oceanic volcano.

He reasoned that a fringing coral reef surrounding a volcanic island in the tropical sea will grow upwards as the island subsides ( sinks ), becoming an " almost atoll ", or barrier reef island, as typified by an island such as Aitutaki in the Cook Islands, Bora Bora and others in the Society Islands.

The fringing reef becomes a barrier reef for the reason that the outer part of the reef maintains itself near sea level through biotic growth, while the inner part of the reef falls behind, becoming a lagoon because conditions are less favorable for the coral and calcareous algae responsible for most reef growth.

In time, subsidence carries the old volcano below the ocean surface and the barrier reef remains.

The barrier reef that forms the basis of Aitutaki is roughly the shape of an equilateral triangle with sides 12 kilometres in length.

The western side of the atoll contains many of Aitutaki's important features including a boat passage through the barrier reef allowing for anchorage close to shore at Arutanga.

Towards the south of the side is a small break in the barrier reef, allowing access for small boats to the lagoon which covers most of the southern part of the triangle.

As the subsidence continues, the fringing reef becomes a barrier reef, and ultimately an atoll reef.
