Listen underwater, process sound at the sensor, and move the data into monitoring workflows. Ocean Sonics builds smart digital hydrophones and acoustic systems in Nova Scotia.
Operating context
Ocean Sonics supplies icListen smart hydrophones for recording, streaming and networked underwater sound measurement. Sensor-side digitization and configurable bandwidth, storage and communications make the deployment architecture important alongside the hydrophone itself. A January 2026 research paper provides a substantial Arctic reference: icListen HF measurements at Cambridge Bay supported analysis of May and August soundscapes across 2015–2024, with instrument and pandemic gaps. The work includes noise from small vessels, aircraft and snowmobiles, extending the picture beyond conventional shipping indicators. Ocean Sonics also participates in Oneka’s C$4.1 million wave-powered desalination and AI-monitoring consortium; that is the total project value, not revenue allocated to Ocean Sonics. These sources support environmental acoustic monitoring and integration discussions without establishing a tactical target-classification system.
Canadian footprint
Ocean Sonics has a documented Canadian operating presence in Truro Heights, Nova Scotia, Canada. Its public organization and capability evidence should be read at that location and national scope only where the cited sources explicitly support it.
Truro, Nova Scotia is the published city-level context for Ocean Sonics. It does not imply a street address or exact facility location.
icListen combines hydrophone sensing, digitization, processing, recording and Ethernet streaming. The current full specification sheet distinguishes 200 kHz HF variants from 13 kHz AF variants, with different maximum sample rates. It lists 24-bit conversion and 1 TB storage, while the 2025/26 guide specifies software and firmware compatibility. Ocean Networks Canada documents scientific deployments and hardware-dependent orientation measurements. This supports environmental monitoring and instrument integration, without establishing tactical classification performance.
Evidence of maturity
Commercial hydrophones with observatory documentation. Current variants and historical hardware revisions differ; RB9 is marked discontinued on the downloaded sheet.
Commercial availability
Available as hydrophones and deployment configurations. Confirm exact sensor variant, firmware/software compatibility, calibration, power and storage before quoting endurance or network capability.
Core features
HF and AF variants with different bandwidth and sampling limits
24-bit conversion and 1 TB onboard recording
Ethernet streaming and synchronized-array integration
Lucy II and Marco compatibility tied to firmware version
Recorded applications

Questions for a first conversation
01
Which sensor bandwidth, deployment depth, power and communications package fits the monitoring objective, and what labelled data would support any proposed event-classification performance?
Adds long-term Arctic research evidence and a clearly bounded industrial consortium role.
Original sources 11 linked records
These records support the organization, its owned capabilities and their reviewed connections. A source count is not a count of independent confirmations.
True North Map derives this first-conversation question from the documented Ocean Sonics capability, current evidence and the decision gap that remains.
Ocean Sonics's public evidence establishes its current role and offering, but it does not answer every access, configuration, eligibility, maturity or buyer question needed for a first business-development conversation.

A January 9, 2026 peer-reviewed study uses icListen HF data at about 8 m depth in Cambridge Bay, analysing May and August samples across 2015–2024 with instrument and pandemic gaps. It examines contributions from snowmobiles, aircraft and small vessels as well as shipping. This is long-term Arctic soundscape evidence, not uninterrupted coverage or a validated defence classifier.
