The OCEAN Project’s Vision for Safer Navigation

Tue, 11 Nov 2025 13:53:17 GMT

Collisions between vessels and whales are increasingly recognized as a preventable threat to both marine life and maritime safety. As global shipping traffic expands, critical whale habitats, especially migration and feeding corridors, have become high-risk zones for accidental strikes. Every year it is estimated that thousands of whales are injured or killed by vessel strikes.

The OCEAN Project (Operator-Centered Enhancement of Awareness in Navigation), a three-year European Union and United Kingdom initiative, is addressing this challenge head-on by integrating advanced hydroacoustic technology and artificial intelligence as one solution to help ships detect and avoid whales in near-real time.

Peterhead Port sonar data flythrough

Wed, 03 Sep 2025 14:00:10 GMT

Peterhead Port, located on Scotland’s northeast coast, is home to one of the UK’s most historically significant maritime structures: two large vertical outer breakwaters totalling 1300m in length, in depths of up to 20mCD. Constructed between 1892 and 1956 to form a harbour of refuge, these breakwaters protect the Port from the full impact of the North Sea. With portions now over a century old, the structures remain critical to day-to-day port operations, and their preservation is essential to ensuring the port’s continued functionality and success.

Vertical detection mode for SeaBat

Wed, 03 Sep 2025 13:49:17 GMT

Traditional multibeam sonar systems have historically struggled with accurately detecting vertical structures, often facing issues such as multipath interference, which can degrade data quality. The typical bottom detection algorithms are not designed to handle the complexity of these environments effectively. However, with the introduction of Vertical detection mode, Teledyne Marine has redefined the standard for vertical-structure surveys, delivering exceptional accuracy and improving data quality, particularly in environments challenged by multipath interference from structures like sheet pilings.

Vertical detection mode is engineered to conquer these challenges with a 'purist' approach. Each detection is processed to stand on its own merit, independent of adjacent beams or historical data. This ensures that true features are captured without compromise, maintaining the integrity and detail of the vertical structures.

Tracker Ensures Clean data and Efficient Mapping

Wed, 28 Aug 2024 10:13:01 GMT

See how the SeaBat T-Series tracker option can instantly improve your survey data. In this example, the outer beams are too weak (marked with blue), resulting in noisy data. The range is too long, leading to low ping rates. With Tracker enabled, the appropriate range settings are automatically identified. We also observe that the beams provide a stronger seabed response (marked with green), reducing the risk of false detections. Finally, you'll notice the swath angle opens up. Here Tracker detects that more data is available, producing a larger swath and ultimately saving ship time.

Tracker Automatically Adjusts Short Range Settings

Wed, 28 Aug 2024 10:12:49 GMT

This is a classic case where the range is set too short, causing the outer beams to be out of range of the seabed. The result is noisy data, extensive data cleaning, reduced coverage, and lost ship time. This scenario can easily occur when the depth changes without the operator noticing. With the SeaBat T-Series Tracker option enabled, less monitoring is needed as it will ensure the range is adjusted correctly whenever the depth changes.

Tracker Rescues Poor Data and Swath Coverage

Wed, 28 Aug 2024 10:12:24 GMT

This example first demonstrates poor data quality. Not only is there significant noise due to poor detections, but there are also data gaps (Holidays) leading to reduced swath coverage. Ultimately, this results in extensive manual cleaning, tighter line spacing, and repeated survey runs. In all cases, users spend more time on their surveys to get it right. The cause of these poor data is inadequate sonar settings. This often occurs with inexperienced users, or users unable to continuously monitor sonar settings, or in uncrewed operations where uninterrupted focus on sonar settings is challenging. Once the user enables the SeaBat T-Series tracker option, the settings are automatically adjusted within a few pings, allowing clean data to be recorded at the maximum possible swath width.

Adaptive Gates Follow Complex Seabed Terrain

Wed, 28 Aug 2024 10:12:13 GMT

Gates aid in bottom detection by minimizing false detections. Any gate can follow a flat seabed, but the SeaBat T-Series comes with unique adaptive gates. As seen in this example, the gates follow both flat terrain and steep cliffs. This is one of the ways the SeaBat T-Series produces the best data and the widest swaths.

Normalized Backscatter Maintains Data Integrity

Wed, 28 Aug 2024 10:11:57 GMT

In this example, you will observe that while the user adjusts sonar settings such as power gain, absorption, and spreading, the backscatter remains unaffected. The SeaBat T-Series sonar accurately measures the seabed response because the normalized backscatter is adjusted to account for these sonar settings. Normalized backscatter allows users to adjust sonar settings without compromising the quality or integrity of backscatter data. This flexibility in data collection ensures that changes in parameters such as gains do not influence the measurement of backscatter strength, ultimately facilitating more accurate analysis and interpretation of underwater features.

Tracker Prevents Oversaturation in Backscatter Data

Wed, 28 Aug 2024 10:11:47 GMT

In the SeaBat T-Series sonar wedge, the beams are now color-coded by intensity. Red/orange beams indicate that the signal is reaching saturation levels, which should be avoided as it leads to poor backscatter. Once the SeaBat T-Series Tracker option is enabled, the settings are adjusted almost instantly to match the seabed response. You will notice that the beams turn green, indicating an adequate response level. Some outer beams are blue, showing that the signal is too weak. Subsequently, Tracker will adjust those so that the beams are just right. SeaBat T-Series Tracker ensures that good backscatter data is collected by avoiding weak or oversaturated beams.

Tracker Optimizes Swath Width for Maximum Efficiency

Wed, 28 Aug 2024 10:11:12 GMT

Here, the T-Series SeaBat tracker option controls the swath width, which was initially set very narrow. Tracker determines that a larger swath is possible and begins to open up the swath angle. This allows users to operate hands-free, confident that the SeaBat sonar is achieving the most efficient swath coverage, avoiding any loss of survey time.

Surveying Artificial Reefs with a SeaBat T51

Tue, 25 Jun 2024 10:50:59 GMT

Artificial reefs make a great playground to produce stunning data when passed over with a SeaBat T51 at 800 kHz. But aside from that they have a more meaningful purpose.

Artificial reefs allow for sea life to recover from a decline in habitat. These reefs act as a recruitment, growth and resting zone for fish species and other sea life.

Artificial reef structures come in all shapes and sizes; giving species places to hide, allowing to live off the seafloor from predatory species, or providing a substrate to grow on.

Surveying the wreck of the HMS Hood (1891)

Tue, 23 Apr 2024 11:35:47 GMT

See how Teledyne Marine surveyed the wreck of HMS Hood with the Teledyne RESON SeaBat T51 800 kilo hertz multibeam echosounder.

In August 2023, Teledyne Marine set out to survey the wreck of HMS Hood (1891). The purpose of the survey was to document the status of the wreck with the latest in high resolution sonar technology.

The wreck is located at the entrance of Portland Harbour, Dorset, UK. HMS Hood was built in 1891 with an impressive length of 125 meters. In 1914, after 20 years of service, she was deliberately sunk to act as a “blockship,” to stop U-boats or torpedoes from entering the port.

Still faithfully resting at the harbour entry, the wreck of HMS Hood, once a popular dive spot, is deteriorating with age and it is understood, no longer safe to dive on.

By using the Teledyne RESON SeaBat T51 800 kilo hertz multibeam echosounder with the full swath and the smallest available receiver beamwidth, Teledyne Marine determined the status of the ship – delivering detailed, and accurate images of this largely forgotten piece of local naval history.

Scottish Association for Marine Science (SAMS).

Product grant: Teledyne RESON SeaBat T50-R Multibeam Sonar / INS

The project's aim is to assess the physical stability of the seafloor in the extremely energetic tidal flows of western Scotland, UK: The Gulf of Corryvreckan and the Falls of Lora, Loch Etive.

The nature of the seabed beneath extreme tidal flows (flow speed > 4m/s) has been little studied, mainly due to the obvious operational challenges posed by the area's hydrodynamics. However, these regions are now receiving research attention due to their value for renewable energy and the insights into turbulent flows that they can bring.

As a student researcher, I am working with a team from the Scottish Association for Marine Science (SAMS) on plans to develop survey techniques for mobile bedform analysis. By comparing two bathymetric data sets (one collected in 2012, and one using Teledyne equipment scheduled for 2020), bedform migration rates and thence the physical stability of the seabed can be quantified.

v2.0 update for SeaBat T-series by Uni Bull

Mon, 30 Mar 2020 14:09:25 GMT

Contact marine-supportDK@teledyne.com with your License-ID today to get your new free valuable SeaBat v2.0 update to enhance your SeaBat capabilities and survey experience.

Teledyne Marine is pleased to announce several new features to our world leading multibeam echosounders the SeaBat T20 and SeaBat T50 - the free of charge SeaBat v2.0 update and now the ability to purchase for your T20 our unique Normalized Backscatter. The SeaBat v2.0 update is applied to your SeaBat by our easy-to-use SeaBatUpdater, so you can easily update your existing SeaBat T-series hardware with these valuable features.

The SeaBat T-series v.2.0 update launches 1024 beams and Sonar UI visualization enhancements at no extra cost, and now has availability for you to acquire Normalized Backscatter for your SeaBat T20.

With the new v2.0 update Teledyne Marine now introduces 1024 true beams, as well as always having 1024 Soundings, for all single head SeaBat T-series products. The increase from 512 to 1024 beams gives you improved target detection capability due to the extremely high data density, leading to more precise surveys and shorter survey time.

For projects where you need to have a minimum of counts in a grid cell, 1024 beams make it possible to fulfil that requirement, increasing your possibilities to win more projects.

Another significant improvement in the SeaBat v2.0 is the visualization feature update to the Teledyne Marine Sonar User Interface (SUI). Adding color by depth, to the already intuitive wedge history display, takes the operator to the next level, making the experience even more intuitive. The real time interpretation of the seabed helps you faster identify your survey area aiding productivity.

In the SUI you are now able to save the raw S7K files directly to your available drives - this function has been moved from the back end to the SUI - so giving you an easy and time saving set up by avoiding going out of the SUI to save your files.

Finally, the v2.0 update for the SeaBat T-series enables our unique Normalized Backscatter output to also cover the surface based SeaBat T20-P and SeaBat T20-R. When you purchase this license, you will have the possibility to increase the use of your existing SeaBat T20 with multiple deliverables from a single survey. The backscatter is compensated for the effects of sonar settings which enables you to collect improved bathymetry data and true backscattering estimations at the same time, thereby reducing survey time and costs.

Using Multibeam SONAR Technology Through the Life of Marine Construction...

Mon, 20 Jan 2020 09:07:29 GMT

In marine construction projects, work is often done “in the blind”. Using multibeam SONAR technology can aid this process in all phases of the project. Pre-construction scans can provide a base line look at an area. This can help put real numbers on quantities as well as highlight any anomalies in the project area that may have otherwise gone unnoticed. This additional information increases the accuracy of estimates and the effectiveness of planning. During the construction phase, multibeam SONARs mounted on construction barges can provide real-time progress updates allowing the operator to work with the most up to date information. The SONAR data integrates seamlessly with marine construction machine guidance software to create a total solution package. In the Post-construction phase, multibeam SONARs can be used to create As-Built surfaces of the finished product as well as validate that build specifications were met. This presentation provides recent, real-world examples of multibeam SONAR use during marine construction project phases as described.

The Technological Evolution of Dredging

Wed, 15 Jan 2020 13:10:31 GMT

From its inception in the late 1800's, the hydraulic, or pipeline, dredge has been the dominant machine used for near-shore and in-shore sediment transportation in the United States. These dredges were initially deployed to maintain sufficient channel depths to facilitate river navigation, port access and development. Infrastructure development after World War II created an inland market for sand and gravel mining dredges used in the production of concrete and asphalt. This material dredging market is at least an order of magnitude larger than the navigational dredging market in the US. Other public and consumer concerns, such as environmental remediation and coastal restoration, have created niche dredging strategies and equipment.

Learn more about Teledyne Marine dredge and construction solutions>

Hydraulic dredges have evolved from steam powered, manually controlled devices to sophisticated, energy efficient machines designed to present minimal negative effects on the environment. The equipment being manufactured today incorporates advanced algorithms to predict pipeline lengths, elevations, particle grain size, and required transport velocities. Many of these machines assist the operator in controlling the dredge's navigational path and speed as well as the production rate. In the next several months, several dredges in North America will be deployed with autonomous capabilities that include artificial intelligence and real-time sub-surface imaging and mapping with the primary goal of increased efficiency with less risk.

Teledyne RESON SeaBat T-Series Multibeam Sonars and Turbidity in Real-Time...

Fri, 10 Jan 2020 15:14:10 GMT

During most dredging operations, survey verification of having met grade and other contract requirements comes after the dredge has completed its work in a designated work area and hence moved on. What if the post-dredge survey reveals that the dredge has not fully met contract obligations? When this happens, the additional time, effort and expense to get the dredge back into position to remove what was missed can undermine the success of a project. What if the dredge operator could have “eyes under water” and confirm that grade requirements have been met before moving on?

During dredging operations, the material on the bottom is disturbed and released into the water column. Turbidity is a measure of the presence of suspended particulates. The more suspended solids in the water column, the higher the turbidity. High turbidity can create issues for sonar performance in that the suspended solids act as an acoustic reflector.
As barge mounted sonars are being used in the marine construction industry more frequently, dredge operators are considering the use of sonar to provide information in advance of post-dredge surveys. The “As-Building” benefits can be substantial but there is a concern over the effect turbidity can have on the acoustics.

Utilizing the Teledyne RESON SeaBat T-Series advanced bottom tracking abilities in various dredging operations, with varied levels of turbidity, we have begun to both demonstrate the value and quantify the limits of sonar usage during dredging operations. This presentation presents our results thus far.

Experimental verification of underwater noise localization based on...

Wed, 20 Mar 2019 13:58:27 GMT

To improve the stealthiness of underwater vehicles, or reduce impacts of vessels on the marine environment, it is necessary to identify their noise sources. Furthermore, the proper acoustic control and management of underwater noise radiation of vessels is critical during the intended upgrades and operational service.

Near-field acoustic holography (NAH) is a technology that acquires sound pressure in the vicinity of the hull, which can be back-propagated to locate the hot-spot on the hull and forward-propagated to predict the far-field radiated noise of the vessel. With OROS Underwater Holography software, which is the only underwater NAH solution in the market, the use of NAH for noise localization and far-field prediction will be presented through the findings from an experimental study on a large scaled model. Considering the typical shape of underwater vehicles, cylindrical NAH is adopted to provide the highest accuracy. A partial circular array consisting of 25 RESON hydrophones is placed in the vicinity of the hull to measure sound pressure. A shaker excited at random is mounted in the hull to simulate a source, whose location is known. The acoustic maps generated from the experimental measurements show good correlation between the hot-spot location and the known source location, verifying the correctness and efficiency of NAH technology in naval applications.

The California Aqueduct is the principal water-conveyance structure of the California State Water Project. From the Sacramento River delta east of San Francisco, it runs south 444 miles (715 km) and is the world’s largest water-conveyance system. Channel sizes vary along the aqueduct, varying from 40 feet (12 meters) to 150 feet (45m) wide at the base, with 30 feet (9 meters) average depth of flow. Additionally, with its unique mixture of over chutes, under chutes, and utility crossings, it has a height clearance limit of 24 inches (0.60cm). Constructed starting in 1960, there are concerns that fluctuating land-surface elevations due to subsidence and uplift in the valley could cause serious operational-maintenance and design construction problems for the California Aqueduct surface-water delivery system. As a result, the California Department of Water Resources has undertaken this study to develop a greater understanding of the location, extent, and magnitude of subsidence along the California Aqueduct, as well as to help understand the relationship of groundwater levels and land subsidence. Since 2005, there have been three unsuccessful attempts to field test a vehicle capable of transiting the canal system with minimal need to recover the vehicle, while having the ability to carry high-resolution multibeam and LiDAR sensors. In December of 2017, Seafloor proposed the development of a 15 foot (4.5m) catamaran vehicle, capable of 8 hours endurance, less than 60cm in overall height, and capable of carrying an IDH T-50 multibeam and high resolution LiDAR sensor. This presentation will produce the results of that program.

Current and future applications of acoustic scanning in marine engineering...

Tue, 15 Jan 2019 08:29:01 GMT

The study highlights the advantages of using acoustic scanning in the survey of key walls, piles, defensive and other civil marine engineering structures, addresses existing and potential problems with this method and suggests a direction for future improvement. It is based on the summary of 25-year experience of marine engineering surveys by GT Corporation SE (Estonia) and its partners, with 10-year experience in acoustic scanning. The key distinction of mentioned application is in very rigorous quality requirements for engineering surveys, very small size (0.5-2cm) of details required, as well as technical problems of scanning vertical structures with high reflective capabilities due to high inclusion of metal components. An additional difficulty are the weather conditions and water qualities specific to the Baltic Sea. To solve this task, the company and its partners use multiple Teledyne products, including PDS software, Seabat T20, Seabat T50, Blueview scanners, all of which will be mentioned during the report with examples of use. Based on the multiple use cases, potential future applications, and expanding engineering survey market it can be seen that a specialized new scanner product type specifically designed for engineering surveys can be used to provide even more informative and higher quality data to potential customers.

Combined Multibeam and LIDAR survay 2017

Tue, 13 Mar 2018 14:25:21 GMT

A video from a survey to monitor changes in a historical structure over time. The breakwater, which is between 200 and 300 years old and stretches for two kilometres, has suffered damage during storms many times over this period. Annual surveys will create a record of the structure as it currently stands and comparisons between datasets will enable detection of sub-centimetre movements over time.

The survey combines LIDAR and Multibeam scans to produce a single model of above and below water.

Difference models show

Erosion (scour) or deposition of sediment.
Displacement of rock armour
Subsidence of structures
Ross of material.

LiDAR scans were done above water with minimum possible water level to ensure maximum survey area coverage.

Laser Scanning of:

Rock armour revetments
Vertical masonry walls
Masonry and concrete paved areas
Slipway
Lighthouse

Multibeam scans were done below water level, at suitable tidal level to allow overlap of results with above water laser scan survey.

Sonar Scanning of:

Vertical walls,
Slipway,
Rock armour revetment,
seabed bathymetry and features.

The surveys were compared at all locations. The comparison has been done between the original survey (2015) and the current survey, using either:

Point Cloud comparison (distance Cloud to Cloud)
Mesh comparison (After modelling the point cloud into a surface),
Profile section across the seabed and the structures

Why Would You Put a Multibeam Sonar on a Construction Barge?

Fri, 19 Jan 2018 15:45:56 GMT

Abstract:

How can I use GPS – I need results in the field. I can't use RTK GPS because it's not accurate enough. Multibeam SONAR systems will never be affordable to anyone but government agencies. Why would you put a GPS unit on a bulldozer? These are all comments and questions commonly heard by and asked of the author, over the course of his career, and in their initial years of introduction, for what have all become truly transformative technologies.

Fortunate in having been exposed to each of these technologies as they were outliers at the left-hand side of the Technology Adoption Curve (TAC), otherwise known as “Innovators", the author presents a broad overview of the development and user implementation timeline of GPS and SONAR technologies. As he fills the area under the TAC with anecdotal recollections of Early Adopter, Early and Late Majority and, let's not forget – the Laggards.

Interesting enough, the technologies as referenced herein, have collectively returned to the Innovator portion of the Technology Adoption Curve. The author now hears the question, “Why would you put a SONAR on a construction barge?" Reference cases of multibeam SONAR installations on construction barges are given showing that the Early Adopters have begun filling in their “area under the curve" and the days of the Early Majority users are soon to follow.

Perspectives on the State of Ocean Science

Tue, 14 Nov 2017 09:51:10 GMT

Keynote presentation by Margaret Leinen

The value and role of ocean science and innovation increasingly has been the focus of both international and domestic forums on climate science, sustainability, and defense. Now in its second century of exploration and research, UC San Diego's Scripps Institution of Oceanography is rising to meet new challenges to understand and protect the planet, through interdisciplinary and cross-sector collaborations and a continued focus on developing innovative technology to observe the planet.

Scripps shares its science at international forums such as the United Nations ocean and climate conferences to advise, contextualize and strengthen the efforts of nations, NGO's and policymakers that set and meet standards for sustainable use of the oceans. The United States Navy is also in the midst of assessing the global state of ocean science and technology via Task Force Ocean, and has engaged US academic institutions including Scripps to ensure cutting-edge ocean science is applied to its oceanographic infrastructure, technologies, and technical workforce so that the Navy maintains its global competitive advantage.

In her keynote, Dr. Margaret Leinen will describe these international forums, Scripps role, how Scripps scientists are innovating to meet these global demands in ocean science and technology, and the state-of-the-art research facilities, centers, and education that will shape the future of ocean and climate science.

The Next Great Odyssey of Human Endeavour Exploring the Deep Ocean

Thu, 09 Nov 2017 14:55:25 GMT

Keynote presentation by Oliver Steeds

Humankind is poised to make the next giant leap – into the deep ocean. We now have the technology available to us to discover more of our planet in the next 10 years than we have in the last 100,000.
Throughout human history, exploration has always driven our progress. Lief Ericson's journey to North America (1001 AD), the discovery of the New World (1490s), Magellan's first circumnavigation (1519) and space exploration (1957-) have all pushed back the frontiers of our knowledge, unlocking immense opportunity and changing our relationship to our planet and ourselves.
But since 1969, we've been looking up when we should have been looking down. The most important part of our planet, the deep ocean, remains the least known part of our planet.
The ocean is the heart of our planet. It's 99% of the planet's biosphere[1], regulates our atmosphere and climate and produces 50% of the oxygen we breath[2]. It captures heat and carbon dioxide which dramatically reduces global warming and provides a primary source of protein for 3 billion people[3]. The ocean is everybody's business. How it changes affects us all. The problem is that we don't know how the deep ocean functions, how healthy it is, how resilient it is and how the development of a sustainable blue economy can drive our growth.
The ocean remains the last great unknown frontier on our planet. We've only biologically sampled 0.0001%[4] and mapped an area equivalent the size of Tasmania to the same kind of detail that we have mapped the entire orbs of the Moon and Mars[5].
From Autonomous Underwater Vehicles (AUVs) to Remotely Operated Vehicles (ROVs), from seabed mapping systems and chemical sensors to the initial library of DNA sequences of marine animals, technological developments now unlock extraordinary new research capabilities. We now have the ability to discover more of our planet in the next 10 years than the last 100,000 of human history.
New areas of economic activity such as renewable energy and marine mining are on the horizon. Millions of new species are to be discovered that can propel human medicine. Resources to be unearthed that will drive our sustainable economic development. Even the origins of life on Planet Earth are to be found.
To engage the world in our all of our work, we should be looking to the space community to learn how to improve our story-telling – engaging our audiences with stories that are positive, forward looking and about a brighter future; that are Mission based and trigger the imagination, communicating danger and building on narratives of exceptionalism, patriotism, exploration and the collective human achievement.
Together, as an industry, we are already leading the exploration of the deep ocean, the last, great unknown frontier on Planet Earth.
The Apollo Missions, polar exploration, Jacques Cousteau's adventures, even Felix Baumgartner's space jump captivated the world with their human drama, battles against adversity, and above all, the unknown. We need the unknown. It is the sense of mystery that gives us imagination and makes us human. Our work is the next positive epic story of human endeavor that can inspire humanity.

Data images from the Multibeam Survey of the HMS Hampshire wreck site

Wed, 24 May 2017 10:45:55 GMT

Earlier this year Teledyne RESON was invited by Seatronics to assist with the mapping of HMS Hampshire.

HMS Hampshire sank on the 5th June 1916 when she struck a mine laid by German U-Boat U75. The wreck is located in approximately 60 meters of water off the west coast of Orkney and sank while en-route to Archangel in Russia. She was transporting Lord Kitchener, Secretary of State for War, to a meeting with Tsar Nicholas II.

Many sailors perished that day and as such the wreck site is considered a war grave and restricted area for shipping and diving. In the run up to the centenary of the loss of the HMS Hampshire permission was given to carry out a condition survey and map the extent of the wreck site.

Sandra Henry continues: “This survey is being undertaken as a mark of respect and remembrance for those who lost their lives aboard, and all those who lost their lives at sea during the First World War.”

Equipped with a SeaBat T-50-P the wreck site was mapped in great detail. The imagery confirmed previous findings that HMS Hampshire capsized as she sank and lies with an upturned hull on the seabed in approximately 60m of water. The superstructure itself is compressed and the hull is damaged in places throughout the length of the vessel. The data was recorded and processed with Teledyne PDS.

Dago

Tue, 28 Mar 2017 09:43:46 GMT

The steamship Dago was built in England in 1912 as a cargo ship. The ship was taken into use by the Russian navy during WWI, and was rebuilt as an armed minesweeper carrying the bow number 4. Dago was anchored West of Osmussaar island on 23 October 1915 due to bad weather, when she was attacked by the German submarine U-9. The torpedo was shot from a short distance and hit the minesweeper right in the center. The vessel foundered immediately.

7 Seven crew members were killed.

Monitoring Basking Sharks in the waters of Coll in the Inner Hebrides of...

Wed, 04 Jan 2017 14:58:35 GMT

Biologists from Aberdeen University wanted to find out if sonar equipment could be used to learn more about the movements of basking sharks. Most of the current knowledge about basking sharks is based on what is visible at the surface and, as such, an investigation was sought to determine if surface observations matched what was happening below the surface. In particular, the scientists were interested to know if the sharks were 'stacking', and whether there was evidence of young sharks.To support this research, Teledyne RESON supplied Aberdeen University with a SeaBat 7128 forward-looking multibeam imaging system. The project was carried out from 7-9 August 2012 off the waters of Coll in the Inner Hebrides of Scotland. Basking sharks are known to reside here and sightings are particularly common at this time of year.

Combined Laser/Multibeam Sonar Survey of Sydney Harbor

Fri, 06 May 2016 10:34:02 GMT

By Dario Conforti - Teledyne Optech

Combined Laser/Multibeam Sonar Survey of Sydney Harbor

Teledyne Optech has been a world leader in the design, development and manufacture of advanced lidar instruments for 40 years. In the last few years Teledyne Optech and its sister company Teledyne RESON developed a full and seamless integration between their sensors, the motion-compensated ILRIS-3D laser scanner and the SeaBat 7125 Sonar System, through the PDS 2000 software. The ILRIS Motion Compensation (MC) option was developed to let surveyors use the normally static ILRIS dynamically by combining it with a Position and Orientation System (POS) and Global Positioning System (GPS) receivers. The resulting system is integrated into a mobile mapping system and enables much more effective mapping in wide and complex terrain. This type of mobile laser scanning is now at the cutting edge of coastal survey technology because it allows surveyors to easily survey coastlines directly from a boat and is particularly useful for mapping long or inaccessible coastal areas. This presentation will explain the integration of the ILRIS and SeaBat sensors and showcase several applications in the last few years from Europe to North America to Australia. The survey in Sydney, Australia is the most recent survey made and shows the perfect match between the underwater data from the sonar and the shore data collected from the lidar scanner.

The history of the SeaBat Sonar

Wed, 02 Dec 2015 09:47:04 GMT

Uni Bull, Senior Product Manager at Teledyne RESON, guides you through the evolution of the SeaBat sonars, starting with the first commercial forward looking sonars from the early 90′s to the newly released SeaBat T-series multibeam echosounders.

Uni Bull describes the sonar evolution like this:
“The early sonars were good then, a bit like the commodore 64 computers, but compared to the technology of today, they have a hard time.”

SeaBat 7130 Sonar

Thu, 19 Nov 2015 20:36:46 GMT

We conducted the first demonstrations of the SeaBat 7130 together with Teledyne PDS at the Teledyne Marine Technology Workshop in San Dieo, October 4-7. The SeaBat 7130 is our most advanced sonar providing long range 3D forward looking bathymetry at 200kHz, and high resolution 2D imagery at 635kHz.

First demonstration with Teledyne PDS Software

This was the first ever demonstration utilizing Teledyne PDS software for processing and visualizing 3D forward looking bathymetry in real-time.

The 3D bathymetry mapped features such as sand waves and rock structures on the sea floor, and the 2D high resolution imagery was visualized as a geo-referenced overlay on top of the generated bathymetry provided a new and unique perspective on the underwater environment.

More details

The SeaBat 7130 is a High-Resolution Forward-Looking Sonar System designed specifically for 12 ¾ inch (approx. 324mm) AUVs/UUVs. The SeaBat 7130 operates at 200 kHz and 635 kHz illuminating a wide, 120° horizontal sector ahead of the Sonar Head Assembly. The high frequency 635 kHz provides high-resolution classification functionality, whereas the lower frequency 200 kHz provides long-range detection capability.

The 200kHz array consists of 3 distinct sub-arrays, distributed in the vertical direction, which is processed in the real time enabling vertical height discrimination of targets ahead of the sonar.

The SeaBat 7130 is primarily intended for use on AUV/UUVs, but also applicable to ROVs and small submarines – and is depth rated up to 3,000m
