;s first.The first show attracted some 600 people, exhibitors and visitors, including British Labour politician and Minister for Technology, Tony Benn (pictured right opening the inaugural evel). 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

Maritime Systems drone market which is primarily comprised of Unmanned Underwater Vehicles (UUVs) and Unmanned Surface Vehicles (USVs).Until recently, conventional side scan sonars have been the leading technology for detailed mapping and imaging of the seafloor. 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

Scientist Pool Data to Create the $3B Ocean Map

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

underwater vehicles (AUVs).The aim of the Innovate UK-supported Precise Positioning for Persistent AUVs (P3AUV) project is to enable AUVs to operate at high levels of navigation performance with less surface support and for longer periods.The provider of underwater acoustic, inertial, optical and sonar technology said in a release that with partners L3 ASV and the National Oceanography Centre (NOC), Sonardyne will focus on longer-term navigational accuracy for AUVs in deep water, while reducing power requirements and increasing autonomy in marine operations.The P3AUV project will involve trials using

Sonar Helps Find Missing Argentine Submarine

EdgeTech, a manufacturer of high-resolution sonar imaging systems and underwater technology, said its side scan sonar technology was used to help find the missing Argentine submarine, ARA San Juan, which was recently located in 900 meters of water off Argentina's Atlantic Coast after a yearlong search.The deepwater search was performed by Ocean Infinity and its advanced fleet of 6,000 meter rated autonomous underwater vehicles (AUV) equipped with EdgeTech 2205 Side Scan Sonars. The ARA San Juan was imaged by the EdgeTech sonar operating at a frequency of 230kHz and a 400-meter range scale.EdgeTech&r

Artificial Intelligence Aids Subsea Object Detection

A developer of real-time 3D sonar technology and real-time subsea intelligence has launched a new product that uses artificial intelligence (AI) to automatically detect and recognize distinct underwater objects.Coda Octopus announced Tuesday that it is launching the initial product of its AI-based Automatic Object Detection (AOD) software product series, the Survey Engine Automatic Object Detection Package (SEADP), which enables geophysicists to automatically accomplish the previously painstaking and costly task of manually sifting through data to identify, tag and report on boulders within a seabed

Sonardyne’s growing portfolio of underwater acoustic positioning, inertial navigation, wireless communications and sonar technology systems are extremely well placed to serve and support these evolving, growing and important markets,” Paull said.Sonardyne’s systems are already established in the offshore renewables market, where its Ultra-Short Baseline (USBL) technologies are used in areas including unexploded

CCOM at UNH Partners with FarSounder

The Coastal and Ocean Mapping (CCOM) at the Joint Hydrographic Center at the University of New Hampshire has added 3D forward-looking sonar technology expert FarSounder as a partner in its Industrial Associates Program.Students in the CCOM program are working toward becoming experts in the field of ocean mapping. With the addition of FarSounder’s technology, the students have the opportunity of hands on experience with this unique technology and the potential to apply the data collected to their research.In addition to providing students the benefit of identifying obstacles ahead of the ship

SES Orders Teledyne Odom Singlebeam Echosounders

Marine said it has scored a significant order from Texas-based Survey Equipment Services (SES) for a number of its new singlebeam echosounders, the Teledyne Odom Hydrographic Echotrac E20.The Echotrac E20 is the next generation of Odom Hydrographic’s singlebeam echosounders, built on new sonar technology at the factory in Denmark, Teledyne Marine’s Sonar Technology Center of Excellence.Designed for ease of use and portability, the Echotrac E20 is a dual channel survey echosounder operating from 10 to 300 kHz operating frequency and from 0.2m to 6km depth range, delivering precise depth
