Coastal Barrier-Lagoon Systems: Evolution and Dynamics in North Carolina

Explore the morphodynamics and sedimentary processes of barrier-lagoon systems in North Carolina's Albemarle Sound and Pamlico Sound regions. Discover the emergence, submergence, and breach models of barrier origin, along with the impact of rising sea levels on coastal evolution. Learn about tidal marsh formation, overwash processes, and the growth of Mississippi subdeltas. Gain insights into barrier morphology models and the resulting geologic record in transgressive and regressive coastal settings.
