2012 Map of Grand Gosier Islands OE E

About this map

The Gulf of Mexico dominates this specific coastal quadrangle in Plaquemines Parish, representing a maritime expanse where open water meets the atmospheric and hydrographic shifts of the Louisiana shoreline. While the map designates this as part of the Grand Gosier Islands vicinity, the absence of landmass on this particular sheet illustrates the dynamic and often submerged nature of the outer barrier island system. Produced by the U.S. Geological Survey using imagery from 2010, the map serves as a geographic baseline for this offshore sector, documenting a moment in time before further shifts in coastal bathymetry or shoreline retreat altered the local coordinates.
