The Grand Gosier Islands and Curlew Islands emerge as fragile landforms in this coastal survey, where the Breton Sound meets the open Gulf of Mexico. This map documents a dynamic marine environment within the Chandeleur Islands chain, specifically highlighting a known subsidence area where the interaction between sediment and sea is constantly shifting. Beyond the natural island topography and designated Shallow Areas, the map records several industrial Platforms located in the surrounding waters. These features illustrate the overlap of natural barrier island conservation and offshore energy infrastructure at the close of the twentieth century, providing a baseline for the eroding shoreline of Plaquemines Parish.
