In 2011, the Office of Coast Survey completed a multi-year project to merge all of the regional maritime limits into a single seamless digital dataset. Because U.S. maritime limits change, based on accretion or erosion of the charted shoreline, Coast Survey, in conjunction with the U.S. Baseline Committee, continually maintains the dataset. When NOAA releases a new nautical chart the maritime limits and boundaries are updated as needed. This page highlights regional or local updates to the dataset.
