Description: Automated Wreck and Obstruction Information System (AWOIS) shipwreck layer, containing shipwreck features that have been compiled since OCS initiated the AWOIS database in 1981 for use in hydrographic survey planning to investigate possible navigational hazards within US coastal waters. AWOIS is presently maintained and updated, however it is not a comprehensive inventory of shipwrecks, as emphasis is continually placed on wrecks that may be a hazard to navigation, and features that have been disproved or salvaged are not included.

Description: Automated Wreck and Obstruction Information System (AWOIS) obstructions layer, containing obstruction features considered navigational hazards that have been compiled since OCS initiated the AWOIS database in 1981 for use in hydrographic survey planning. AWOIS is presently maintained and updated, however it should not be considered a comprehensive inventory of navigational hazards.

Description: A merged set of wreck features from OCS’ Electronic Navigational Charts (ENCs), containing best-available coverage for a given area using supercession for areas with large scale ENCs (approach and harbor scale) and smaller scale ENCs (coastal, general, overview) for areas with no large scale coverage.
