NOAAS Bell Mr. Shimada (R 227)

NOAAS Bell Mr. Shimada (R 227) is an American fisheries researcher with the National Oceanic and Atmospheric Administration (NOAA) since 2010. She operates along the United States West Coast .

The ship was named by Marina High School students in Marina , California , who won a NOAA vessel-naming contest held as part of an educational outreach program. The ship’s namesake, Bell M. Shimada (1922-1958), served with the Bureau of Fisheries and the Inter-American Tropical Tuna Commission , and was known for his studies of tropical Pacific tuna stocks. [1]

Construction and commissioning

Bell M. Shimada Was ugly down by Halter Marine, Inc. , at Moss Point , Mississippi , is 15 June 2007 [2] and lancé on 26 September 2008. [1] On 21 January 2010, Halter Marine Delivered her to NOAA, qui commissioned her on 25 August 2010. [3] [4]

Characteristics and capabilities

Capable of Conducting Multidisciplinary Oceanographic Operations in Support of biological , chemical , and physical processes studies, Bell M. Shimada Was commissioned as the fourth of a class of five of the MOST advanced fisheries research vessels in the world, with a single capability to conduct Both fishing and oceanographic research. It is a stern trawler with fishing capabilities similar to those of commercial fishing vessels . She is rigged for longlining and trap fishing and can conduct trawlingoperations to depths of 3,500 meters (11,483 feet). Her MOST advanced feature is the incorporation of United States Navy -type acoustic quieting technology to enable NOAA scientists to monitor fish populations without the ship ‘ s noise altering the behavior of the fish, quieting Including advanced features incorporated into her machinery, equipment, and propeller . Her oceanographic hydrophones are mounted on a retractable centerboard, or drop keel , which lowers scientific transducers away from the region of hull-generated flow noise, enhancing the quality of the collected data. To take full advantage of these advanced data-gathering capabilities, she hasScientific Sonar System , which can accurately measure the biomass of fish in a survey area. She aussi HAS year Acoustic Doppler Current Profiler with qui to collect data are ocean currents and a multibeam sonar system That provides information on the content of the water column and on the types and topography of the seafloor while she is Underway, and she can gather hydrographic data at any speed up to 11 knots (20 km / hr). [3] [4]

Bell M. Shimada has an oceanographic winch with a maximum pull weight of 6,800 pounds (3,084 kg) which can deploy up to 5,100 meters (16,732 feet) of 16-mm wire. She also has two hydrographic winches with a maximum pull weight of 2,600 pounds (1,179 kg), each of which can deploy 3,600 meters (11,811 feet) of 9.5-mm wire, two trawl winches with a maximum pull weight of 7,200 pounds (3,266 kg) each of which can deploy 4,300 meters (14,107 feet) of 28.6-mm wire, and a hydraulic third-wire winch which can deploy 4,700 meters (15,420 feet) of 11.4-mm electromechanical cable. She has a 67-foot (20.4-meter) knuckle boom and a 60-foot (18.3-meter) telescopic boom. She has a movable A-framewith a maximum safe working load of 2,979 pounds (1,351 kg) and a large movable A-frame with a maximum safe working load of 22,000 pounds (9,979 kg) that serves as a stern gantry . The oceanographic winch and A-frame wide after-work in conjunction to serve her stern sampling station, while two winches work with the starboard-side A-frame to serve her side sampling station, and Bell M. Shimada ‘ s configuration Allows her to-have three scientific packages ready for sequential operations. One of her winches can also be seen here. In addition to trawling, her sampling stations can deploy net smaller sampling, longlines, and fish traps. Her winches can deploy CTD instruments to measure theelectrical conductivity , temperature, and chlorophyll fluorescence of sea water. Bell M. Shimada aussi can deploy Specialized gear Such As Multiple Opening / Closing Net and Environmental Sensing System ( MOCNESS ) frames, towed vehicles, Dredges , and bottom corers , and she can deploy and recover Both floating and bottom-moored sensor arrays. While trawling, Reuben Lasker uses wireless and hard-wired systems to monitor the shape of the trawl net and to work with an autotrawl system that sets trawl depth and trawl wire tension and adjusts the net configuration. [3]

Bell M. Shimada has a 591-square-foot (sq. Ft.) (54.9-square-meter) (m²) wet laboratory , a 206-sq.-ft. (19.1-m²) dry laboratory , 270-sq.-ft. (25.1-m²) Chemistry Laboratory, 474-sq.-ft. (44.0-m²) electronics and computer laboratory, and a 179-sq.-ft. (16.6-m²) hydrographic laboratory. She also has a 61-sq.-ft. (5.7-m²) climate-controlled space, at 402-sq.-ft. (37.3-m²) walk-in scientific freezer, 9-sq.-ft. (0.8-m²) scientific chest freezer, at 55-sq.-ft. (5.1-m²) scientific refrigerator, and a 65-sq.-ft. (6.0-m²) store room. She has opened a deck of space on the beach and is working on a computer. All of her discharges empty off her port side so that fluids will not be contaminated at the station on her starboard side. [3]

Bell M. Shimada carries a 26-foot 6-inch (8.1-meter) SOLAS -approved rescue boat with a 144- horsepower ( 122- kilowatt ) motor and a capacity of six people. [3]

In addition to her crew of 24, Bell M. Shimada can accommodate up to 15 scientists. [3]

Service history

Officially classified as a “fisheries survey vessel” and with his home port at Newport , Oregon , Bell M. Shimada operates in support of the Northwest Fisheries Science Center in Seattle , Washington , and the Southwest Fisheries Science Center in La Jolla , California , both Components of NOAA ‘s National Marine Fisheries Service . She operates along the entire United States West Coast , conducting both oceanographic and fisheries research. She monitors fisheries and protected species including yellowfin , sharks, salmon , groundfish , sardines , and hake , makes observations, conducts habitat assessments, and surveys marine mammals and marine birds . [1] [4]

When NOAA commissioned the NOAAS survey fisheries vessel Reuben Lasker (R 228) – home-ported at San Diego , California – in May 2014 and assigned to fish surveys , marine mammals, and sea ​​turtles off the US West Coast and the eastern tropical Pacific Ocean , Bell M. Shimada Was freed to focus on high-priority projects That prior to Reuben Lasker ‘ s arrival HAD beens Allocated no dedicated sea time, Including studies of the California Current Large Marine Ecosystem entre British Columbia and Baja Californiaand of salmon populations all along the US West Coast. [5]
