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)

Kongsberg M3 Sonar on Teledyne Seabotix Observation Class ROV

The Kongsberg M3 Sonar system can be mounted on the Teledyne Seabotix vLBV Observation Class ROV. The M3 Sonar is a 2D multibeam echosounder system with sophisticated imaging and profiling capabilities. It provides high-resolution and easy-to-interpret images by combining the rapid refresh rate of conventional multibeam sonar with image quality comparable to a singlebeam sonar. The M3 Sonar integration package developed by Teledyne Seabotix enables detection of small objects at distances of more than 150 metres combined with a 120° to 140° field of view, allowing the operator to see the complete underwater picture in real-time. It features multiple modes... (read more)

UKHO Ensures Safe Arrival of Aircraft Carrier into Portsmouth

The United Kingdom Hydrographic Office (UKHO) supported the safe arrival of HMS 'Queen Elizabeth' into Portsmouth on 16 August 2017 by providing specialist marine geospatial and hydrographic expertise and data capabilities. Following initial dredging operations to make Portsmouth’s navigation channel and entrance deeper, hydrographic data was collected by the survey launch HMS 'Gleaner' using multibeam echosounder technology to confirm the available water depth. As well as providing advice during data collection, the final dataset was then validated by the UKHO to ensure it was the to the highest Category Zone of Confidence - a criteria used to determine the accuracy...

Canadian Coast Guard Expands Northern Mapping Capability

The Canadian Coast Guard has chosen Kongsberg Maritime to provide high-resolution EM 712 multibeam echosounders to the Canadian Coast Guard’s medium icebreakers, CCGS Pierre Radisson and the CCGS Des Groseilliers. Gathering critical hydrographic data can be a challenge in the Canadian Arctic. The retractable design of the EM 712 echo sounder systems optimises performance of the sounder when deployed and protects it when the vessel is breaking ice. When deployed, the high-resolution EM 712 collects navigational and scientific data from otherwise inaccessible parts of the planet and is capable of mapping a swath of the seabed up to 3,000 metres...

EchoBoat Used for Delta Levee System Survey

The SEAFLOOR EchoBoat USV is on the job for the California Department of Water Resources (CADWR) and R.E.Y. Engineers surveying the fragile delta region levee system. The EchoBoat is Seafloor’s 1.8m remotely controlled survey platform, which is also capable of autonomous and semi-autonomous operation. Integrated to the vehicle are a Norbit iWBMSc multibeam echosounder and a Velodyne Puck Lidar sensor. The laser-multibeam combination allows the customer to scan the levee structure for integrity above and below the water line simultaneously. Since 1900, there have been over 160 levee failures in the Sacramento-San Joaquin River Delta. These numbers include multiple failures... (read more)

French Bathymetric Survey Vessel Renovated and Refurbished

Located on the western border between Basque Country and Gascony, the harbour of Bayonne belongs to the region Nouvelle-Aquitaine, which is under obligation to provide information to the various harbour operators about the depths in the areas of the harbour. MacArtney France supplied the multibeam solution for the bathymetric survey vessel Ingénieurs Lesbordes and is the integrator of the various steps of modification that were imperative to the successful adaptation of the vessel to the prevailing IHO survey standards. The bathymetries produced are essential for navigation (permissible draft, obstacles) and dredging operations (decision support, control) and they are also necessary for the... (read more)

World Hydrography Day 2017 for HSB: Looking behind the Dikes

Hydrography is important to visualise the water floor. This can be done in various ways, from using a sounding stick to a remotely controlled singlebeam echosounder or a survey vessel manned 24/7. On Tuesday 20 June 2017, the worlds of dredging and hydrography were united at the offices of Waternet in Amsterdam, The Netherlands, most importantly to learn from each other during the Hydrographic Society Benelux (HSB) workshop. World Hydrography Day was also celebrated during a social event at the RIC Rowing Club. When do you apply which technique? How can you best map the depth and structure of the... (read more)
