Water: Ocean Survey Vessel
OSV Bold Brochure (2005)
Welcome Aboard The U.S. EPA Ocean Survey Vessel Bold
The Ocean Survey Vessel Bold (OSV Bold) is EPA's new ocean and coastal monitoring ship. With plans to operate in the coastal waters of the Atlantic, Pacific and Gulf of Mexico , the OSV Bold will provide EPA with valuable monitoring and assessment information on the health of our nation's coastal waters.
EPA's mission includes protecting our nation's coastal and marine resources from the degrading effects of pollution. Monitoring and assessment play a crucial role in providing needed information on the physical, chemical and biological status of our coastal resources. EPA will rely on monitoring information taken onboard the OSV Bold to observe changes from pollution and to develop management and planning strategies to protect and preserve our ocean and coastal resources.
OSV Bold's Mission
The OSV Bold supports EPA's efforts to monitor and assess impacts on ocean and coastal waters from land- and ocean-based human activities and naturally occurring ecological disturbances.
Keeping Channels Open For U.S. Ports
Harbors naturally fill with sediment. Dredging is necessary to maintain navigational passage for ships in our nation's ports and harbors. Once removed, dredged material is often disposed of in coastal waters. Impacts from disposing dredged sediment are generally minimal, but could be significant if the placement of sediments alters existing habitat. Under the Marine Protection, Research, and Sanctuaries Act, EPA is responsible for designating and monitoring sites for dredged material disposal. The OSV Bold will aid EPA in managing dredged material disposal by identifying new areas suitable for designation as dredged material ocean disposal sites and monitoring existing sites for any negative impacts. Monitoring ensures that U.S. ports remain accessible without causing environmental harm
Assessing Impacts of Pollution
Over enrichment of waters due to excessive loading of nitrogen is a common problem facing many of our waterways. While there are many sources, two primary contributors are effluent from wastewater treatment plants and runoff from agricultural fields. This overabundance of nutrients can promote harmful algal blooms as well as lead to hypoxia, a condition where waters have extremely low levels of oxygen. The OSV Bold helps EPA monitor areas experiencing environmental degradation from over enrichment, such as the hypoxic zone in the Gulf of Mexico . This major hypoxic event occurs annually in the Gulf of Mexico and degrades habitat for fish and other marine organisms. The OSV Bold will help EPA scientists monitor progress towards reducing the size and the ecological impacts of the hypoxic zone.
Not only will the OSV Bold aid in various monitoring efforts, but it will also serve as a platform for the over 60 EPA certified SCUBA divers in EPA's Dive Program. EPA divers will use the OSV Bold to support monitoring, enforcement, and survey efforts which require SCUBA diving. The ship has a state-of-the-art system that provides divers with enriched oxygen breathing gas. This specialized breathing gas increases diver safety by reducing the risk of decompression illness
Other Types of OSV Bold Surveys
Monitoring and assessment surveys conducted aboard the OSV Boldinclude studying impacts of air deposition, red tides and harmful algal blooms, waste disposal, ocean wastewater outfalls, emergency ocean dumping, and marine debris. Other surveys study vessel discharges, hazardous material spills, and coral reef health.
The OSV Bold is equipped to support various monitoring and educational tasks. The vessel carries sophisticated instruments to collect data on the water column, sediments, and marine life. The vessel also maintains underwater video, sidescan sonar, and general sampling instruments such as corers, dredges, and trawls. Onboard laboratories allow scientists to process, analyze, and store samples.
The OSV Bold will provide opportunities for public education on coastal and marine environments through open houses and demonstration surveys. Other activities include study-on-board student and teacher programs. These popular activities allow interested parties to learn about ocean monitoring and EPA's role in ocean stewardship.

The OSV Bold is the former Navy vessel, United States Naval Ship (USNS) Bold. Constructed by the Tacoma Boat Building Company of Tacoma , Washington , as a Tactical Auxiliary General Ocean Survey (T-AGOS) vessel, the ship was first commissioned in 1989 as the USNS Vigorous . The vessel was later renamed the USNS Bold and has served on many surveillance missions. The Navy decommissioned the USNS Bold in 2004, and then transferred the vessel to EPA . EPA converted the vessel to an Ocean Survey Vessel (OSV) to replace EPA's aging OSV Peter W. Anderson .
