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.

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.

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.

Reefs captured with the RESON SeaBat T51-R Multibeam echosounder

All the images of the artificial reefs are captured with a SeaBat T51 at 800 kHz. For your survey this gives you:

Improved decision making: The frequency flexible 700-800kHz sonar array for up to seven times water depth efficiency - this gives you an extreme resolution that captures all the details you need.
350-430kHz sonar operation for traditional and extended range survey requirements maximising your sonar usage
Hands-free: This model comes with Autonomous Sonar Controls – allowing the operator to focus on other tasks than controlling the sonar
