Multibeam and Imaging Sonar Demonstrations

Teledyne Odom Hydrographic and Teledyne BlueView will be performing demonstrations onboard the survey vessel Meon Surveyor during all three days of Ocean Business 2013 in Southampton, UK. Teledyne Odom will be demonstrating its new Dual Head MB1 Multibeam with integrated Hemisphere Heading RTK Positioning module, and Teledyne TSS DMS-05 Motion Sensor. Each MB1 multibeam installed on the Meon Surveyor features 120° swath width, 170 - 220kHz user selectable frequency range, 24-bit resolution, 60Hz ping rate and up to 512 beams. This new fully integrated model enables users to install and calibrate the system in a fraction of the time of... (read more)

Sonar Linked to Whale Strandings

The first data on how beaked whales respond to naval sonar exercises appears in a new report from an international research team. Their results suggest that sonar affects the behaviour and movement of whales.   Scientists have long been aware of a link between naval sonar exercises and unusual mass strandings of beaked whales. Evidence of such a link triggered a series of lawsuits in which environmental groups sued the US Navy to limit sonar exercises to reduce risk to whales. In 2008, this conflict rose to the level of the US Supreme Court which had to balance potential threat... (read more)

Tri-frequency Sidescan Sonar System

EdgeTech, USA, has released an AUV-based sonar system that provides three sidescan sonar frequencies as well as subbottom profiling capabilities in one compact and integrated system. One of the recently delivered EdgeTech 2205 tri-frequency systems was configured to operate at 230kHz, 540kHz and 1,600kHz. This configuration provides more flexibility for AUV operators and allows them to collect different sets of data for different missions without reconfiguration. The lower frequency provides a 450 metre swath while the higher frequency is suited for high resolution operations. The 1,600kHz frequency can provide across-track resolution of less than one centimetre. In the middle, the... (read more)

Tritech Side Scan Sonar Demonstrations

During Ocean Business, Tritech International will showcase on-water demonstrations of side scan sonars. The range of side scan sonars have been tailored to suit requirements for imaging in shallow and deep waters.   Building on the success of the advanced side scan sonar systems Tritech complete the family with the next generation model, the daddy of the family; The SeaKing Towfish SK150 DST. Specifically designed to fly at depths of up to 120 metres, the SK150 can be used for high resolution surveys at depths other lighter systems can't reach.   The demonstration sessions will be held on board Bill...

Sonar Used for Wreck Discovery

Adventure diver Ben Burville recently trialled Tritech's StarFish Side Scan Sonar off the UK's North-East coast. Ben scanned the seabed at the wreck site of the cargo ship SS Somali which sank under German fire in 1941 off Blyth.   The images provided detail 50m either side of the boat at a depth of 25-30m. Metal shows up white (as it reflects the sonar waves) and different densities give different shades of colour; objects proud of the seabed leave a shadow. Images are divided into port and starboard as it moves forward.Over the SS Somali, it helped pinpoint the location... (read more)

Forward Looking Sonar for Navigation

Safer Navigation with Wider Adoption of FLS
An increasing number of ships are venturing into areas where the only hydrographic data available do not meet the standard many of these vessels require for safe navigation. A number of recent and some not so recent marine casualties have resulted from encounters with uncharted, isolated seabed features (Russell, 2014). The situation is recognised by the IHO; but the necessary improvement to the hydrographic data will take years. Meanwhile, the informed use of Forward Looking Sonar (FLS) could contribute to safer navigation in inadequately charted areas. Present-day commercial FLS developed from its use by fishing vessels and for obstacle avoidance... (read more)

Echoscope Sonar for Dredging International

Unique Maritime Group of UAE has recently delivered two Echoscope 3D sonar to DI-MEDCO, a joint venture between Dredging International and Middle East Dredging Company, for the planned shore protection and harbour construction works of two artificial islands. The Echoscope, produced by CodaOctopus Products, is a sonar capable of producing real-time 3D imagery, enabling the operators of visualise underwater activity in 3D even in zero-visibility conditions. This latest delivery adds to Dredging International’s existing pool of Echoscope systems, further enabling the company to increase the efficiency of its operations. (read more)
