What makes the barrier island special?
Barrier islands are critically important in mitigating ocean swells and other storm events for the water systems on the mainland side of the barrier island, as well as protecting the coastline. This effectively creates a unique environment of relatively low energy, brackish water.
What are Georgia’s barrier islands built on?
Ridges of sand dunes were left above sea level and gradually built into barrier islands. Over the next few thousand years sediments from rivers added material to fill in the area between these new islands and the mainland producing mud in which the vast expanses of salt marsh formed.

How old are the Georgia barrier islands?
between 40,000 to 4,000 years ago
Georgia’s barrier islands formed between 40,000 to 4,000 years ago, with the oldest islands closest to the mainland.
How are barrier islands formed?
As the ice caps melted, the sea level rise flooded the coastal plains. The now offshore drowned dune ridges became the nucleus for an island. Wave action and longshore drift reworked and enlarged the dune ridge into a barrier island. Other barrier islands formed from sandbars.
How do barrier islands move?
Barrier islands form as waves repeatedly deposit sediment parallel to the shoreline. As wind and waves shift according to weather patterns and local geographic features, these islands constantly move, erode, and grow. They can even disappear entirely.
