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.
In additional to design services, eSonar’s product lines include sonar and acoustic systems, data-enabled marine LED lighting, and integrated trawl management (net monitoring) systems. The distinguishing feature of this technology is the capability to sense and acoustically transmit data from deployed equipment back to nearby vessels or platforms for display as easy-to-read, real-time information.
A critical part of our success is the reliable and extended life of eSonar’s power supply. Our engineers use the latest microprocessors to bring cutting-edge power management to subsea instruments. Our rugged design and power management reduces power demand to micro-watts, greatly extending the lifetime of each sensor.
A key feature of our subsea sensors is a synthetic pressure housing that is RF transparent. The advantage of this type of housing for underwater acoustics technology is that equipment settings can be modified and data can be downloaded without opening the sealed subsea enclosures (tested to 2000m submerged depth).
Our lighting division works with major marine lighting companies to deliver next-level solutions in data-enabled LED marine lighting. We transform marine luminaires into data platforms. These networks are connected and powered over Ethernet. This creates a distributed communications network on the vessel, allowing high-speed data access through the lighting system. Built-in sensors in the luminaire combine with the central Ethernet backbone to enhance control of the vessel.
At eSonar we offer advanced high-level and low-level software and firmware capabilities:
Low-level software capabilities include programmable logic, network processors and a specialization in Arm processor types.
High-level software capabilities include user interface, signal processing, instrument control, long term monitoring, data collection and storage, data display and bespoke visualization.
As a result of our focus and advanced knowledge, the acoustics and lighting technology products we have developed are used extensively by marine scientists and companies in Canada, the United States and internationally. Our engineers, software specialists, technologists and technicians are eager to work with you to deliver your next commercial design for subsea application.
OUR MANAGEMENT TEAM
GARY DINN, P. Eng.
Chief Technology Officer
Gary has more than 25 years’ experience in the marine sector in electronics and acoustics, electronic design, mechanical design and project management.
He has a solid record in developing products and technology for international markets. Much of this, he gained while operating his consulting company, M3 Sonar Inc. He was also a founder and director of Rutter Inc. And, more recently, he served as Vice-President of PanGeo Subsea Inc.
Gary holds a bachelor’s degree in Electrical Engineering.
DR. DAVID BUTTLE
David has more than 40 years’ experience in the design and manufacture of underwater acoustic systems.
He was a Design Engineer on remote control of high frequency radio transmitters and receivers for Racal Ltd. He worked on underwater navigation systems before starting Marine Acoustics Ltd., his own sonar design and manufacturing company. There he worked on naval sonar applications.
David holds a 1st class Honours Bachelor of Science Degree from the University of Reading in the UK and a PhD in sonar data telemetry from the University of Birmingham.
Brian has more than 30 years’ experience in the electrical engineering field as a hardware/software developer and project manager.
Before joining eSonar, Brian worked at NorthStar Technical as Vice-President R&D. In that role, he led the team in the development of marine electronics and underwater acoustics. In addition, he served as lead engineer in the development of marine navigation systems. Earlier in his career Brian served as Manager of Information Technology for a National Research Council laboratory. There he was responsible for the development of distributed data acquisition and processing systems.
Before becoming a shareholder in eSonar, Jim was Vice-President of Marport. Immediately prior to that he served as President of NorthStar Technical. Earlier in his career, he was extensively involved with the commercial fishing industry in Newfoundland and Labrador. During his time in the industry, Jim has gained a diverse range of sonar design and marketing expertise as well as significant international experience in marine technology.
Jim is a technology graduate from the Marine Institute of Memorial University.
After investing in eSonar in 2018, Chris became a member of the company’s board. From his base in New York, he worked with Google after it acquired and successfully integrated a start-up where he was employed. Today, as an ex-Googler, Chris is working on his own start-up in Ontario. Earlier in his career, Chris was active in advertising during that sector’s expansion from print into digital media.
Chris studied economics at Memorial University.
