Oceanographers develop new model to better predict barrier island retreat

Barrier islands protect the coastline from storms, storm surge, waves and flooding. They can act as a buffer between the ocean and beachfront property. As sea level rises, barrier islands retreat, or move closer toward the shore, which diminishes the buffer and protection. New information shows the retreat of coastal barrier islands will accelerate by 50 percent within a century, even if sea level continues to rise at its present rate.Barrier islands protect the coastline from storms, storm surge, waves and flooding.
