The Teledyne Marine Slocum G3 Glider and the newest addition, the Slocum Sentinel Glider, are the flagships of Teledyne Marine’s glider fleet and the future of autonomous submersible technology. Set up for continuous, energy-efficient data collection, the Slocum G3 Glider and the Sentinel Glider are all-purpose platforms that are changing how scientists, researchers, and businesses observe and learn about our world’s oceans.

A Workhorse for Modern Oceanography

The Teledyne Webb Slocum G3 Glider has long been a trusted instrument for self-contained ocean observation since 1979, and its data has been used in everything from climate monitoring to fisheries management. With the addition of Kongsberg’s EK80 broadband echosounder, the Slocum G3 will set the tone for underwater data collection, with unrivaled possibilities for scientific and commercial operations. Teledyne Webb Research’s collaboration with Kongsberg Maritime is a step forward in oceanographic technology. The Slocum G3 Glider is a proven, durable, energy-saving, versatile instrument, and the perfect candidate for the Kongsberg EK80. This broadband echosounder provides operators with detailed images, a range of frequencies, and exceptional sensitivity, providing high-resolution data. The integration of the EK80 with the Slocum G3 Glider combines the best of two industry-leading technologies. This system empowers researchers to monitor marine ecosystems with unprecedented precision and efficiency.

Combining the Kongsberg EK80 with the Slocum G3 Glider shows the need for autonomous ocean science becoming ever more pressing. Acoustic surveys using conventional methods are usually time-consuming and carried out using large vessels, making them expensive operations. The glider system, on the other hand, provides an affordable, scalable solution for monitoring over time in the remotest and most challenging of marine settings. Because it reduces noise and disruption, the glider and EK80 setup captures reliable, quality data without disturbing marine life. As the need to make real-time decisions with high-quality data in dynamic marine environments increases, equipment such as the Slocum G3 and EK80 will be vital in defining the future of the ocean. Not only does this alliance confirm the need for cooperation in technological innovation, but it also inaugurates a new era of innovation in ocean exploration and protection.

Teledyne Marine’s Slocum Sentinel Glider, the newest addition to the fleet, is a marvel of engineering. An autonomous subsea vehicle that can extract high-quality ocean data in some of the most remote environments for extended periods. Its proprietary buoyancy-driven propulsion allows it to pass freely through the water column, wasting as little energy as possible and prolonging mission time. Such technology makes it a beneficial instrument for scientific research, environmental monitoring, and commercial applications.

The Sentinel Glider is a breakthrough in marine exploration thanks to the extensive range of technologies it offers for oceanographic surveys and surveillance. But the most astonishing is that it can run autonomously on a mission for weeks or months. This durability makes the glider a good candidate for long-term research and data collection, following the seasons, ocean currents, or marine ecosystems over time with little or no human intervention.

Its sensor flexibility is another significant aspect, as the Sentinel Glider can be equipped with many different sensors based on mission needs. The Sentinel Glider is the next generation of autonomous ocean gliders – this ultra-long endurance uncrewed vehicle allows for over a year of persistent ocean monitoring. It has the size and energy to address the broadest range of oceanographic missions. The wide array of sensors available creates a flexibility that allows the glider to produce high-resolution, multi-dimensional data for climate change studies, aquatic life, and environmental health. Its buoyancy-powered propulsion system uses little power to cover vast distances and gather data. Such a design allows the Sentinel Glider to be used when conditions are harsh or far from shore. It gives scientists a stable vehicle for missions over long periods that would not be feasible by traditional techniques.

Beyond being durable and efficient, the Sentinel Glider is also very flexible in operation thanks to modular construction and easy-to-use software. The modular layouts allow operators to tailor the glider to any job, from coastal inshore surveys to deep-sea exploration. The easy-to-use software interface simplifies mission planning and data analysis, and the Sentinel Glider is open to all users — from university researchers to government agencies to private industry.

Together, these features make the Slocum Sentinel Glider a powerful and flexible platform for today’s increasing demand for high-quality data collection. Its use in climate change monitoring, fisheries, and commercial and military applications illustrates its value and flexibility.

A New Answer to Problems Around the World

With the global environment and geopolitical tensions growing, more accurate and timely oceanographic information is needed than ever before. It is that demand for information in real-time that the Slocum G3 equipped with Kongsberg EK80 Echosounder and the Sentinel Glider is uniquely positioned to provide the highest quality data for climate change, resource use, and marine biodiversity degradation. Whether used for polar research, coral reef surveys, or oceanographic mapping of offshore power stations, the Slocum G3 and Sentinel Gliders clearly show the changes occurring in the dynamic ocean environment. That is why it is a necessary resource for governments, universities, and the private sector alike.

Charting a Sustainable Future

The Slocum Glider fleet is a technology that can empower ocean knowledge and care. In a world where the well-being of the marine environment has become as important as the planet’s well-being, equipment such as the Slocum G3 and Sentinel Gliders can only help make a long-term difference. The Teledyne Marine Slocum G3 and Sentinel Gliders will advance the frontier of discovery just as Doug Webb did, uncompromising in its quest for discovery and innovation. With the Slocum Glider fleet, Doug Webb’s visionary tenacity continues to drive oceanography in its next generation.
