Environmental Sonar Systems

Improve access to subsea environmental data. eSonar’s advanced underwater acoustics technology provides fisheries scientists and fish harvesters with data on the geometry, depth and loading of trawls and seines. Our acoustic systems can also provide important information on detected marine mammals, water temperature, angle of deployed gear, and detected sonar noise.


Marine Carbon Intensity Measurement

Continuous measurement of carbon intensity on marine vessels is made possible by instrumenting carbon inputs, emissions parameters, and direct engine output via propellor thrust.


This capability provides vessel owners with real-time assessment of their energy efficiency and the effect of actions taken to reduce carbon emissions. The combination of this joint Canada-UK capability provides game changing support for managing vessels’ carbon emission, reducing energy intensity and carbon-
footprint of shipping.

Advanced Marine Lighting Systems

Vessels equipped with eSonar’s LED lighting, get much more than a reliable and trusted marine lighting system—they also get a robust data platform that allows high-speed data access via the lighting network.

eSonar’s advanced marine luminaires use Power-over-Ethernet to add high-speed data connectivity to shipboard lighting. Built-in sensors in the luminaire, combined with a central monitoring and data backbone, enhance vessel control.

Our Products
Corporate Profile


Since 2009 we have pursued our mission to improve mariners’ access to marine and subsea environmental data. Our focus is on underwater acoustic technology for the marine and subsea industries. We recently expanded our activity into high-tech marine lighting.


eSonar improves access to subsea environmental data with advanced sonar and underwater acoustics knowledge to help improve the fishing rate for targeted species, protect endangered marine mammals, save fuel, reduce time spent trawling, and monitor gear. Based on our knowledge we take action to create products that are used extensively by fisheries scientists and fishing companies in the USA, Canada and internationally. By providing real-time information on the trawl and seine deployment—shape, depth and catch rate plus more specific data such as water temperature, angular data and sonar around the deployed position.

Our team of sonar engineers and signal-processing experts are engaged in continuous R&D. Their aim is to add new capabilities and improve our products in response to the changing needs of our customers. Applying our knowledge of advanced underwater acoustics technology, eSonar provides solutions for the challenges of operating subsea equipment such as trawls and monitoring buoys.

We work closely with Memorial University in St. John’s NL. Together we design and create technological solutions for industry-specific applications and for cross-industry applications such as autonomous underwater vehicles. We work directly with the fishing industry. We work with shipboard marine industries. We work with offshore oil and gas. And we work with the aquaculture industry.
