| * » Abstract |
Ship wrecks and obstructions in the ocean have long been a hazard to navigation and construction, and a point of interest to archeologist, recreational divers, fisherman, educators and explorers. Locating hazardous wrecks and obstructions is part of the ongoing NOAA charting process. The exact position of many wrecks is difficult to determine because of changes in the environment, varied survey methods, and human error. Some wrecks are intentionally placed in the ocean to serve as artificial reefs or for disposal. Others pose a health and environmental threat from their cargo. Ownership and control over wrecks and obstructions is governed by a collection of state and federal regulations, the Abandoned Shipwreck Act, National Historic Preservation Act, and the National Marine Sanctuaries Act. These data are a synthesis of two sources - the NOAA Office of Coast Survey's 2016 Automated Wreck and Obstruction Information System (AWOIS), and the NOAA Electronic Navigational Charts (ENC). Not included were those records that were clearly identified as natural features such as rocks, shoals, and trees. Features are recorded as either a wreck, wreck area, obstruction, or unknown. |
| * Purpose |
To support ocean planning activities pursuant to the Executive Order Regarding the Ocean Policy to Advance the Economic, Security, and Environmental Interests of the United States, the Energy Policy Act, the National Environmental Policy Act, the Rivers and Harbors Act, and the Coastal Zone Management Act. |

| Analytical Accuracy |
Multiple records at slightly different locations may exist in a small number of cases for a single wreck or obstruction. This can occur when 2 or more sources are used, and the sources do not include sufficient detail to identify the feature. This can also occur when a single wreck or obstruction is mapped at multiple time frames using different survey methods and technology. |

|---|---|
| » Description |
1) Acquire primary sources 2) Normalize the data structure 3) Transform polygon features to a polygon centroid point feature 4) Remove duplicate values from the ENC Approach class when there was co-occurrence within a 100-meter range in the Harbor class 5) Remove characters from the COMMENT field identified as, special, formatting, reserved, and unnecessary white space 6) Standardize all unknown, blank and null-like values to a consistent format 7) Standardize all character fonts to uppercase 8) Remove features clearly identified as natural 9) Amend the OBJECTCATEGORY field when values in the COMMENT field indicate a specific category 10) MERGE the source data into a single point feature class 11) Optimize field type and field size settings |
