Barrier islands are constantly being shaped by factors like accretion, which is the process of sand building up to create new island structures; erosion; waves; and water currents, like longshore currents, which are currents that run parallel to the shore; and changes in climate due to global warming.

Below the surface, the coral turns stark white during the event, and if it does not recover, the whole ecosystem rots. can erode quickly because wave action is concentrated near one level for longer times. The best are those that have been awarded Advanced Ecotourism levels such as Reef Magic cruises in Cairns, Quicksilver Connections in Port Douglas and Tall Ship Adventures in the Whitsundays. For example, in Georgia, when soft summer waves hit the shore, they bring sediment from the sea, allowing the island to increase in size.

A third theory, the submergence theory, says that the barrier islands can be formed by submergence of parts of the mainland, forming a body of water that separates the islands from the mainland. Around 9 percent of the region’s fish are directly dependent on the coral as both a food source and a habitat, and around 65 percent of fish prefer to settle on or near the reef.
