Large sand volume barrier islands: Environmental processes and development risks

By Dirk Frankenberg

This Carolina Environmental Diversity Explorations “virtual field trip” explores the nature and structure of barrier islands with large sand volume — high dunes and sandy ridges that keep the islands’ topography relatively stable. Built structures on these islands are less susceptible to damage from hurricanes than are structures on small sand volume islands. This trip provides high-resolution photographs of two such islands, Bear Island (which has not been developed) and Bogue Banks (which has been developed). Its companion field trip, Small Sand Volume Barrier Islands, should be taken before this trip, for comparison.
