Introduction: This manual has been compiled to provide users of the Automated Wreck and Obstruction Information System (AWOIS) with instructions for obtaining and interpreting data from the system. Background is also available which explains the use of the system as a basic research tool. In 1981, the National Ocean Service (NOS) implemented the Automated Wreck and Obstruction Information System (AWOIS) to assist in planning hydrographic survey operations and to catalog and store a substantial volume of reported wrecks and obstructions that are considered navigational hazards within U.S. coastal waters. Today, over 10,000 reports have been received, which include unverified accounts of vessel casualties, as well as chronological history. As part of the hydrographic survey planning process, these records are reviewed and those wrecks or obstructions which require additional field investigation are assigned to specific field units. The results of these investigations eventually become part of the AWOIS file so that a permanent record of a wreck or obstruction is always available. Besides functioning as a survey planning tool, AWOIS is of potential value to various users outside of NOS. The historical record of selected wrecks, the accessibility of information in a sorted format, and its reasonable cost make AWOIS an important information source for marine archaeologists and historians, fishermen, divers, salvage operators, and others in the marine community. Interested individuals are encouraged to use the system as a supplement to other sources of information. However, AWOIS has limitations that should be considered by potential users. Most notably, it is not a comprehensive record of wrecks in any particular area. Historical research is constantly being conducted to improve the quality of the file, but it will never completely address every known or reported wreck. The emphasis is constantly placed on wrecks which may be a hazard to navigation.
