The Gulf of Mexico dominates this coastal survey, reflecting the maritime character of Saint Bernard Parish in the early 21st century. This specific quadrangle covers a significant stretch of open water where the Louisiana marshlands meet the sea, capturing the shifting nature of the coastline as documented in the 2012 topographic record. While land features are nearly absent, the map serves as a precise geodetic benchmark for coastal change and hydrographic studies within the Gulf of Mexico.
