... Coasts are energetic sedimentary environments; they form part of a sedimentary system,
which extends from catchment headwaters to the deep ocean. Throughout geological time,
relative sea level changes have ensured that beaches and estuaries occupied different
areas of the continental margins. In add ...

Selective submarine erosion appears to be an important process here. The eroded sediments have

... The barrier islands are most relevant in that they are where sea turtles come
to nest. North Carolina has some of the most important sea turtle nesting
areas on the East Coast, due to the proximity of the islands to the Gulf

A lagoon is a shallow body of water separated from a larger body of water by barrier islands or reefs. Lagoons are commonly divided into coastal lagoons and atoll lagoons. They have also been identified as occurring on mixed-sand and gravel coastlines. There is an overlap between bodies of water classified as coastal lagoons and bodies of water classified as estuaries. Lagoons are common coastal features around the world.
