Mitcham Announces MA-X Sonar Product Deliveries

Mitcham Industries said its Klein Marine Systems unit has completed initial deliveries of new products based on its MA-X "gap filler" sonar technology.  Introduced earlier this year, MA-X technology is a cost-effective solution to filling the nadir gap that is characteristic of traditional side scan sonar.  By seamlessly covering the nadir region, MA-X based products eliminate the need for overlapping survey lines, resulting in an estimated 40% increase in efficiency."The reaction by the industry to MA-X we believe has been nothing short of incredible,” said Guy Malden

FarSounder Unveils 3D Forward-Looking Sonar

yachts from 18 - 40+ meters. As in its other two models the Argos 1000 and Argos 500, the design allows for an easy, fixed installation. The Argos 350 however offers another alternative as well. It can be connected to a hoist in a 10-inch diameter sea chest.As the leader in 3D Forward Looking Sonar technology, FarSounder has kept the yachting community safe from shallows and in-water obstacles since 2005. In introducing the Argos 350 to this new market, these smaller vessels can now enjoy FarSounder’s 3D real-time software and navigate with confidence. 

CODA Elects Plumb to Board of Directors

Coda Octopus Group, Inc. (CODA) (Nasdaq: CODA), a leader in real-time 3D sonar technology and real-time subsea intelligence, announced the election of J. Charles Plumb, Captain, USNR (Ret.) to its Board of Directors. Captain Plumb was elected at the company’s annual meeting of stockholders.Captain J. Charles Plumb is a retired U.S. Navy fighter pilot and former Vietnam Prisoner of War. He retired from the United States Navy after 28 years of service, and his military honors include two Purple Hearts, the Legion of Merit, the Silver Star, the Bronze Star, and the P.O.W. Medal. Since his

3D Sonar Used in Fishery Research

A collaborative research project aiming to assess pelagic fish species such as menhaden and herring is using an application of 3D sonar technology to increase sustainability and benefit the commercial fishing industry.In Rhode Island, pelagic fish, like the Atlantic menhaden and herring, are commercially important in supporting a large fishing industry, yet the management of pelagic fish is difficult due to the lack of reliable and adequate data. The goal of this project is to develop a methodology to detect fish in the sonar imagery, calculating the biomass pelagic fish present, classify the species

Among the show’s first visitors was Marty Klein, who was instrumental in bringing side scan sonar technology to commercial market. “There was a lot of excitement about the oceans,” he says. “Cities under the sea were going to feed the world. People were building manned submersibles to go exploring in the deep. Aerospace companies were building submersibles, like Lockheed, North American

Alucia2 Installing FarSounder 3D FLS

The FarSounder-1000 Forward Looking Sonar (FLS), has been selected by the OceanX exploration team to help provide safe passage for Alucia2, its new 85.3m research and exploration yacht. Admarel BV, a member of the Alewijnse Group, is the FarSounder dealer in the Netherlands instrumental in securing this sale.With the inclusion of a FarSounder-1000, operators of the vessel will be able to view a true underwater 3D image ahead of the ship up to 1000 meters range. The sonar’s technology is designed to assist in the prevention of collisions and groundings as the OceanX team explores parts

Sonar Assists Deepest Solo Sub Dive

-- the deepest solo human submersible dive ever.It goes without saying that state-of-the-art subsea technology was key to the mission's success. The submersible, a Triton 36000/2, features a 90mm thick pressure hull and is the first commercially certified full ocean depth.New multibeam sonar technology from Kongsberg Maritime also played a big part in the feat. Utilized for precision mapping, the Kongsberg EM 124 was installed aboard the DSSV Pressure Drop to produce seafloor bathymetry to map the trench."[The EM 124] produced digital 3D renderings of the sea floor that were used to identify

However, Kraken’s advanced sonar technology called Miniature Interferometric Synthetic Aperture Sonar (MINSAS) is now commercially available and is especially well-suited for military mine hunting missions.  MINSAS delivers ultra-high seabed image resolution (3 cm), simultaneously co-registered 3D bathymetry, and superior area coverage

that produced only a "blurry picture", said Mayer.Today, high-tech multibeam echosounders transmit a fan of acoustic beams from a ship, which ping back depending on the depth and topography of the ocean floor. That creates data points, which can be converted into a map."With advanced sonar technology it really is like seeing. I think we've come out of the era of being the blind man with the stick," said Robert Larter, a marine geophysicist at the British Antarctic Survey."We can survey much more efficiently - and, not only that, but in much greater detail," he said, adding
