RUDE Beaufort Obstructions
Picture of NOAA Ship RUDE with fendors deployed getting ready to make landing at pier. The NOAA Ship RUDE surveying in Onslow Bay off Beaufort, NC in March of 2007 located several obstructions in close proximity outside the charted limits of a fish haven. The RUDE surveyed a 600m radius area using side scan sonar to locate the obstructions and multibeam sonar to determine least depths on the individual items. The shoalest depth identified within the debris field was 20ft on an item in an area charted to a depth of 50ft.  A Danger to Navigation (DTON) notice was submitted for application to the nautical charts and publication in the Notice and Local Notice to Mariners.

The NOAA Ship RUDE (pronounced "Rudy") performs hydrographic surveys along the east coast of the United States in support of NOAA's nautical charting mission, specializing in the location and accurate positioning of submerged hazards to navigation. The RUDE is named for Captain Gilbert T. Rude. For more information on the RUDE and other NOAA vessels visit NOAA’s Office of Marine and Aviation Operations.
