Since 2009 we have pursued our mission to improve mariners’ access to marine and subsea environmental data. Our focus is on highly reliable underwater acoustic technology for the marine and subsea industries. We recently expanded our activity to include multi-element listening arrays for marine mammals.

​

eSonar improves access to subsea environmental data with advanced sonar and underwater acoustics knowledge to help improve the fishing success rate for targeted species while protecting endangered marine mammals, saving fuel, and reducing time spent trawling with real-time monitored gear. Our knowledge-based products are used by fisheries scientists and fishing companies in the USA, Canada and internationally. We provide 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 engage in continuous R&D with an aim 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, acoustic releases, and monitoring buoys.

​

We work closely with researchers at Memorial University in St. John’s NL to design and develop technological solutions for industry-specific applications and for cross-industry applications such as autonomous underwater vehicle navigation. 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 our extended development team design services, eSonar’s product lines include sonar and acoustic systems, integrated trawl management (net monitoring) systems, and transducer design. The distinguishing feature of this technology is the capability to dynamically sense and reliably 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 Li-ion power systems. Our engineers use the latest microprocessors to bring cutting-edge power management to subsea instruments. This rugged design methodology combined with power management reduces demand to micro-watts, greatly extending the deployed persistence of our gear.

​

A key feature of our subsea sensors is the RF transparent synthetic pressure housing. This allows equipment settings to be modified, and data downloaded without requiring underwater connectors or opening of the sealed subsea enclosures (tested to 2000m submerged depth).

​

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 Linux development, 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 products and related engineering services we offer 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.
