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.

Autonomously Surveying England’s Only Loch

Thu, 23 Jan 2025 15:10:00 GMT

Recently, Teledyne Marine joined forces with Maritime Robotics and DEEP to survey DEEP’s quarry lake, affectionately referred to as Loch Lyr, a unique site in the Wye Valley.

Loch Lyr serves as the centrepiece of DEEP Campus, a cutting-edge facility developed by the visionary company DEEP, whose mission is to “make humans aquatic.”

Spanning 50 acres, this former National Dive Center offers an unparalleled environment for testing subsea equipment, developing methodologies, and training personnel in controlled conditions. The loch itself stretches 500 meters in length, up to 125 meters in width, and plunges to an impressive 80 meters of depth. Its water quality is pristine, maintained by innovative measures such as perimeter curtains designed to limit debris from entering.

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.

SeaBat T-Series v2.0 update. Introduction and demo

Fri, 27 Nov 2020 10:28:11 GMT

SeaBat is the world’s leading sonar brand in seabed mapping.

A SeaBat sonar is specifically designed to provide the best performance possible. It is designed to solve the task as quickly, effortlessly, efficiently, accurately and as user friendly as possible.

Measuring a distance may sound easy, but transmitting mechanical wave fronts (sound) from a non-stationary platform (boat), into a dynamic and highly absorbent medium (water) and very accurately detecting and analyzing extremely weak sound signals that return, in real-time, is an incredible engineering challenge that only very few companies master – and a SeaBat sonar does this up to several millions times per minute.

TM Academic Grant Winner - Christian Armstrong - Teledyne RESON SeaBat T50-R...

Thu, 30 Jul 2020 17:20:00 GMT

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.
