USVs Developing into Versatile Tools

Extending the Boundaries of Hydrographic Surveying
Unmanned surface vehicles (USVs) are gaining terrain in hydrographic surveying. They combine the advantages of small survey vessels with those of unmanned survey platforms, giving them a range of applications that is likely to expand even more. They enable hydrographic surveys in a greater number of areas, both inland and offshore. Due to the size of some USVs, they can access waters that are either too shallow for a regular survey vessel or difficult – even dangerous – to access to allow mobilisation of a manned survey vessel. This makes them the survey platform of choice for inshore and coastal areas like... (read more)

Kongsberg Unveils New-generation Multibeam Echosounder

Kongsberg Maritime has released the EM 304, the third generation of its de facto industry-standard 30kHz multibeam echosounder system, which is used for high-resolution seabed mapping from depths of 10 metres to beyond the continental rises, deeper than 8,000 metres. Developed as a low-noise echosounder with state-of-the-art electronics, the EM 304 delivers high-quality data that requires minimal post-processing. In addition to offering increased range and resolution performance, the EM 304 introduces a broad range of functionality and new features that serve as a significant upgrade to the current generation EM 302 system. EM 302 Replacement As part of a new... (read more)

Fugro to Bring Survey Expertise to Search for Lost WWI Submarine

Fugro is to join a campaign to find the First World War Australian submarine, HMAS AE1. From its survey vessel, the 'Fugro Equator', skilled survey personnel from Fugro will use a multibeam echosounder to conduct a bathymetric survey as well as an autonomous underwater vehicle for close examination of the search area. The expedition will be led by the not-for-profit-company Find AE1 Ltd and supported by Fugro, the Australian National Maritime Museum and the Submarine Institute of Australia. The Silentworld Foundation, a not-for-profit organisation with a focus on Australasian maritime archaeology, and the Royal Australian Navy are the major sponsors... (read more)

Forth Ports to Use NORBIT Multibeam Echosounder

NORBIT has supplied Forth Ports, one of the UK’s largest port groups, with multibeam survey capability for the River Forth and the River Tay. The NORBIT iWBMSh is in place with QPS QINSy and Qimera software, along with associated sensors and training with an investment by the port business exceeding GBP250,000. NORBIT has also supplied the integrated iLiDAR system to Forth Ports, facilitating an integrated survey system allowing both bathymetric and terrestrial spatial data to be simultaneously collected by a single source system. Alan McPherson, Chief Harbour Master commented that as the statutory River Authority for the River Forth and... (read more)

Greenland Climate Research Centre Invests in Multibeam Echosounder

The Greenland Climate Research Centre will be taking delivery in early 2018 of a Teledyne RESON SeaBat T50-R extended-range high-resolution multibeam sonar. The sonar will be hull-mounted on R/V 'Sanna'. R/V 'Sanna' operates as a research vessel on the West Greenland coast, collecting valuable data about Greenland’s marine resources and oceanographic environment. The Greenland Climate Research Centre is a part of Greenland Institute of Natural Resources, and the researchers will utilise the Seabat T50-R ER capabilities to map seabed topography and marine habitats in the 200-800m deep waters of the Greenland shelf. The SeaBat T50-R Extended Range builds on the market leading SeaBat T-series, which is designed... (read more)

Offshore Geophysical Survey Underway for AQUIND Interconnector

MMT has commenced an offshore geophysical survey for the AQUIND Interconnector project. The work will involve a geophysical survey of the proposed cable corridor between the landfall areas near Portsmouth in England and near Dieppe in France. MMT will utilise two vessels: M/V Franklin for offshore works and M/V Seabeam for nearshore works. The vessels are equipped with survey technology including multibeam echosounders, sidescan sonars and sub-bottom profilers. AQUIND, MMT and their representatives maintain ongoing contact with UK and French fisheries, which may be affected by the survey, in order to mitigate any potential impact on their fishing activities. The... (read more)

Teledyne Gavia Awarded Contract for 6,000m-rated AUV

Teledyne Gavia has recently been awarded a contract for the supply of a 6,000m-rated AUV for deep water search and recovery applications for delivery in 2018. The newly designed SeaRaptor AUV will incorporate a broad range of Teledyne content. The payload will be including acoustic modems, a flight data recorder beacon locator and sub-bottom profilers (Teledyne Benthos, Falmouth, MA, US), multibeam echosounders and obstacle avoidance sonars (Teledyne RESON, Denmark), Doppler Velocity Log (DVL) and Current, Temperature, and Depth sensor (CTD) (Teledyne RD Instruments, San Diego, CA, US),  and on-board processing software (Teledyne Caris, New Brunswick, Canada). In addition, the vehicle... (read more)

Portable Remotely Operated Singlebeam Survey Boat

The Teledyne Oceanscience Z-Boat 1250 is a remotely operated hydrographic survey boat that is sturdy enough for tough terrain but light enough to be one-person portable. It is outfitted with a singlebeam echosounder and is suited for inland waters such as streams, rivers and lakes. Teledyne Oceanscience Z-Boat 1250’s trimaran style boat has a lightweight hull manufactured from ABS plastic. The 1250 is IP67 rated, which makes it suited to survey in most water conditions. Thanks to its collapsible sliding crossbar, the new Z-Boat 1250 is easily transported by a single operator making surveys in remote areas possible.  The new... (read more)

Acoustic Zooplankton Fish Profiler (AZFP) for Ecosystem Research

The US Naval Research Laboratory has purchased an Acoustic Zooplankton Fish Profiler (AZFP) autonomous echosounder to conduct observations of small zooplankton for ecosystem research. The internally powered scientific echosounder will store acoustic backscatter data. It will be mounted to an apparatus that will move the instrument up and down the water column in order to observe the dynamic behaviour of zooplankton. The technology employed by this echosounder uses multiple high frequencies to ensonify the small particle sizes of the zooplankton. The Navy will use the instrument to support ongoing research in coupled, ecosystem-circulation modelling, underwater optics and remote sensing.   (read more)

High-resolution Mapping of Deep-sea Vertical Walls Using AUVs and ROVs

A study published by the National Oceanography Centre (NOC) combines autonomous underwater vehicle (AUV) and remotely operated vehicle (ROV) mapping and imaging methodologies to reveal the complex 3D terrain of deep-sea vertical cliffs and the diversity of species associated with them. AUVs and ROVs can get much closer to the seafloor and generate higher-resolution maps than would be possible with ship-mounted multibeam echosounders. Deep-sea cliffs associated with submarine features such as canyons and escarpments, can host a wide range of species including a particularly high number of ecologically important cold-water corals. The complex habitat created by these corals provides other animals with living... (read more)
