Case stories

A 16-Year Legacy of Sustained Ocean ObservationSince January 2009, the University of Western Australia’s (UWA) IMOS Ocean Glider team has been at the forefront of autonomous ocean observation. With unwavering commitment, the team has launched or recovered ocean gliders every week for 16 years, culminating in the 400th mission in May 2025. This milestone marks a significant achievement in marine science, innovation, and collaboration, supported by the Integrated Marine Observing System (IMOS) and National Collaborative Research Infrastructure Strategy (NCRIS).Learn more >

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.Learn more >

On October 11, 2025, Redwing—a next-generation Slocum Sentinel Glider​—was launched into the Atlantic Ocean off the coast of Massachusetts. Guided by the rhythms of the sea and the promise of discovery, Redwing will collect ocean data, dodge fishing nets, and surf powerful currents, all without a human onboard. Its journey will span the Gulf Stream to Europe, south to Gran Canaria, onward to Cape Town, across the Indian Ocean to Australia and New Zealand, through the Antarctic Circumpolar Current, and eventually back to the Atlantic via the Falkland Islands, Brazil, and the Caribbean.The mission aims to revolutionize ocean data collection, improve weather forecasting and our understanding of the causes of extreme weather events, and inspire the next generation of ocean scientists and engineers.Learn more about the Sentinel Mission

The goal of this project was to establish a comprehensive library of images documenting the wrecks of two historically significant ships: the HMAS Sydney II and the HSK Kormoran. These images were intended to support the creation of multi-platform museum exhibitions, preserving the unique heritage value of these vessels for future generations and honoring the lives lost in what remains Australia’s greatest naval tragedy.Learn more>

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. Read the case study>

Teledyne Marine’s Sea of Solutions personified in the stunning images and important data collected by NEKTON’s First Decent mission. First Descent is a series of expeditions combining innovations in technology, AI, big data and communications, in a bold bid to accelerate the scientific exploration and conservation of the Indian Ocean, the world’s least explored and least protected ocean. How the Indian Ocean changes in the coming decades will profoundly affect the lives, livelihoods and wellbeing of 2.5billion living in the region. First Descent begins in the Seychelles and continues with other expeditions across the Indian Ocean. First Descent: Indian Ocean concludes with the State of the Indian Ocean Summit in 2022 in Oxford. Teledyne Marine supplies the expedition with Software and essential sonar, camera, light, and navigation technology. Learn more at https://go3.teledynemarine.com/NEKTON

Teledyne Bowtech’s Surveyor-HD-Pro cameras were deployed on the submersible vessels used during the research gathering stages of Nekton's NW Atlantic Mission (Summer 2016). The Surveyor-HDPro is an ultra wide angle HD colour zoom camera with water corrected optics. It is a unique combination of widest angle vision and compact engineering to produce an extremely dynamic and well engineered system. Excellent images can be obtained through the fused silica hemispherical window, some of which can be seen as part of the Nekton and Teledyne Marine collaboration video detailing this mission. Video surveying of unexplored ecosystems down to 300m was principal to Nekton’s research, and with operating pressures up to thirty atmospheres, low temperatures, very low ambient light and rugged terrain often surrounded by fast currents, the environment was one of the toughest and most challenging ever experienced. Nekton required only the most advanced and highly robust systems to operate and succeed with the research gathering.

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. Read the whole case story: http://www.teledyne-reson.com/news/monitoring-basking-sharks/

Traditionally, SeaBat deepwater sonars have been known for being quite difficult to move around, but that is about to change as Teledyne RESON has built a portable SeaBat 7150. The entire system is built into a container making it the world’s first portable SeaBat deepwater sonar system. This particular system was developed to plan routes for underwater cables and pipelines.- This is the latest member of the SeaBat 7150 sonar family and it is one quarter of the size of the first system we built. We have taken the high resolution portions of one of our deep water mapping systems and put it in a very portable system, explains Paul Jubinski.Contact us for more information>He adds that the aim was to make a multibeam system that you can take anywhere in the world without having to transit a multibeam-equipped vessel.  Equipping a vessel that already is near to the survey area can vastly change the budget for a small survey located far from the nearest multibeam-equipped vessel. Teledyne RESON has designed and built all of the sonar components and the electronics in the portable electronics enclosure.  Furthermore, the system uses the same standard sonar processor which is used in all the SeaBat 7150 sonar systems. So, even though it is a small compact system it has all the capabilities that teledyne RESON offers in even the largest of the 7150 sonar systems.A standard 20-foot shipping container was modified by Stabbert Yacht and Ship (a division of Stabbert Maritime, Seattle, Washington, USA) to produce a truck and ship portable van that can transport all of the sonar system components and then serve as a well-appointed lighted, air-conditioned work space on the deck of the survey vessel. The arrival of the containerized SeaBat 7150 can turn a suitably prepared vessel into a deep-water survey platform after a few days of mobilization dockside.
