DFO Uses OEI Hydrophone Arrays to Monitor North Atlantic Right Whales

Fisheries and Oceans Canada (DFO) researchers used Omnitech Electronics’ DASA-2591 hydrophone arrays for long-range acoustic monitoring of North Atlantic right whales in the Gulf of St. Lawrence, detecting calls at ranges of approximately 10–80 km and beyond.

During a 24-day deployment in August 2021, two 20-metre circular arrays surveyed a 3,600-square-kilometre area. Combining directional acoustic processing with deep-learning detection, the system detected 3,117 right whale upcalls and localized 30% within the arrays’ shared detection area.

Published in The Journal of the Acoustical Society of America, the study examines the system’s capabilities and operating constraints, including its performance under elevated human-generated underwater noise.

DEFSEC Atlantic 2026

Omnitech Electronics will be exhibiting at DEFSEC Atlantic 2026 from October 6–8 at the Halifax Convention Centre. If you’ll be at the show and would like to meet with our team, we’d be happy to arrange a time during the event or afterward. Please contact us to set something up.  

Hydrophone Arrays Delivered to JASCO

Omnitech Electronics Inc is pleased to announce that it has delivered a set of bespoke hydrophone arrays built on our LDHA technology to JASCO Applied Sciences , a world leader in underwater acoustics. The new arrays are designed to be deployed in Arctic waters, where it will deepen understanding of underwater acoustics in the region.

DEFSEC Atlantic 2025

Last week at DEFSEC, we discussed how our custom engineering solutions solve complex defence challenges. Great to connect with customers and partners and explore new opportunities to solve hard technical problems together. If we missed you at the show, we look forward to connecting soon.

OCEANS 2024 HALIFAX and DEFSEC Atlantic 2024

Omnitech Electronics will be exhibiting at OCEANS 2024 HALIFAX from Sep 23-26, and the Canadian Defence Security and Aerospace Exhibition (DEFSEC ATLANTIC 2024) from Oct 1-3 at the Halifax Convention Centre. If you plan to attend and would like to schedule a meeting during or after the show, please contact us.  

Omnitech Electronics Provides Unique Array

Omnitech Electronics has completed delivery of a unique underwater acoustic array. Designed in conjunction with the Swedish Defence Research Agency (FOI), the array will support Sweden's ongoing defence research goals in the underwater acoustic domain.
