The newly constructed National Oceanic and Atmospheric Administration fishery survey vessel Henry B. Bigelow has exceeded international standards as an acoustically quiet vessel, according to a report released by the U.S. Navy.
NOAA received the results from a battery of underwater acoustic tests done by the Navy on the ship at the Atlantic Undersea Test and Evaluation Center on Andros Island in the Bahamas.
â€œHenry B. Bigelow is one of only a handful of research ship
s in the world that have met this high standard as a quiet research vessel,â€ said retired Navy Vice Adm. Conrad C. Lautenbacher Jr., undersecretary of commerce for oceans and atmosphere and NOAA administrator.
â€œWith its dramatically lower background noise levels, this ship will greatly enhance our ability to use the most sophisticated acoustic devices to assess fish stocks.â€
The noise radiated by the 208-ft. vessel was compared by the Navy to noise recommendations established by the International Council for the Exploration of the Sea, a respected international organization that includes more than 1,600 marine scientists from 20 countries that surround the North Atlantic.
â€œBecause Henry B. Bigelow does not produce disruptive background noise, we can count fish and assess the size, health and behavior of stocks with highly sensitive acoustic devices,â€ said William T. Hogarth, director of NOAA Fisheries Service. â€œTrawl surveys also conducted by Henry B. Bigelow will be greatly enhanced by the new acoustic quieting on the vessel because fish and marine mammals will be less likely to react to ship noise. This is an important new tool to support ecosystem research.â€
Henry B. Bigelow is the second in a fleet of four new fisheries survey vessels that
will replace older ships. The first quiet vessel to be launched was Oscar Dyson, which also met or exceeded ICES standards. Oscar Dyson is home ported in Kodiak, Alaska, and conducts research on fisheries in the North Pacific, Gulf of Alaska and Bering Sea. Two more ships of the same class are under construction.
Henry B. Bigelow also represents a major accomplishment for the U.S. shipbuilding industry, which has shown it can construct dramatically quieter vessels using new hull designs and mounting devices for generators, engines and machines aboard the ship.
Henry B. Bigelow was designed in a partnership between NOAAâ€™s Office of Marine and Aviation Operations and the U.S. Naval Surface Warfare Center
, Carderock Division, in Bethesda, Md. The ship was built at VT Halter Marine Inc., in Moss Point, Miss.
Henry B. Bigelow is to be commissioned on July 16, 2007 in Norfolk, Va. She will support research conducted by NOAAâ€™s Northeast Fisheries Science Center in Woods Hole, Mass. and be homeported in New England. The New England base of operations is appropriate for a ship named in honor of one of the giants in oceanography and fisheries research
