Wrecks and Obstructions Database

The Office of Coast Survey’s Wrecks and Obstructions database contains information on the identified submerged wrecks and obstructions within the U.S. maritime boundaries. The data includes the position of each feature (latitude and longitude) along with a brief description and attribution (where available). Information for the database is sourced from the NOAA Electronic Navigational Charts (ENC) and Automated Wrecks and Obstructions Information System (AWOIS).

Database Limitations

  • The database contains wreck features from two different sources that were created for different purposes, and there is not a perfect match of features from either source. The same wreck may be found in both the ENC wrecks and AWOIS wrecks layers, although the positions may not necessarily agree. Additionally, there may be wrecks in the ENC layer that do not appear in the AWOIS layer and vice versa. For more information see the Wrecks and Obstructions Database User's Guide.
  • Updates to the database are limited, with priority given to wrecks that may be hazards to navigation.
  • Wrecks and obstructions that have been salvaged or disproved by further investigation have been removed from the AWOIS database.
  • These data are not for navigation.
