Passive acoustic analytics · Pilot partners welcome

Hear the whales.
Know your range.

V15ION turns underwater sound into decisions: near-real-time orca presence alerts, detection-range maps that update as ocean noise changes, and defensible estimates of how many animals are present. Built on wave physics, array processing and acoustic imaging.


The Problem

An endangered population, and gaps in how we listen

Operators and regulators need clear answers to two questions: is a whale here now, and how much of the area can we actually hear?

~76
Southern Resident killer whales remaining, one of the most endangered marine mammal populations on Earth
1,500 m/s
Speed of sound in seawater, over four times faster than in air. Whale calls carry for kilometres, so the ocean is best monitored by listening
Hourly
How often detection range can change as vessel, wind and rain noise rise and fall. A fixed "listening radius" can badly over- or under-state coverage
24/7
Vessel traffic in critical habitat never stops. Timely presence information lets operators slow down or change course when it matters most

Services

What we deliver

Four services built on one idea: before you trust a detection, or the absence of one, you need to know how well you could hear.

Presence alerts
Near-real-time orca detection from hydrophone networks, with call-type classification, and a location on the map where arrays allow.
Detection range and coverage
Hour-by-hour maps of how far each hydrophone can actually hear, measured from the recordings themselves as noise changes.
Density and abundance
Estimates of how many animals are present, derived from acoustic data, with the uncertainty stated.
Noise and soundscape assessment
Calibrated underwater noise levels, vessel-noise contributions and propagation modelling for environmental assessments and permit monitoring.

How It Works

From ocean sound to actionable intelligence

A five-stage pipeline, from raw hydrophone audio to decisions.

01 — CAPTURE
Hydrophone Capture
Continuous hydrophone audio is ingested together with each sensor's calibration and position.
Real-time or archived
02 — MEASURE
Noise Measurement
Audio is filtered to the band each species uses, and ambient noise is measured in calibrated units, minute by minute.
dB re 1 µPa
03 — DETECT
Detection & Classification
Machine-learning models find calls and sort them by type, separating biological signals from vessel noise, rain and flow.
Validated on local data
04 — LOCATE
Localization & Range
Where hydrophones are time-synchronized, calls are placed on the map. Each sensor's detection range is updated from the measured noise.
Time-difference of arrival
05 — REPORT
Alerts & Reports
Detections stream to a dashboard and API within minutes. Coverage, noise and abundance summaries are delivered as reports.
Streamed alerts, API, reports

Who We Serve

Built for the people who share the water

Starting in the Salish Sea, with methods that transfer to any hydrophone array and any vocal species.

Whale Watching Operators
Know where Southern Residents are so you can keep regulated approach distances, and plan trips with less idle time and fuel.
Shipping & Ferry Operators
Near-real-time alerts support slowdowns and route choices when whales are present, reducing strike risk and underwater noise.
Offshore & Construction
Documented detections, measured noise levels, and a record of how far your monitoring could actually hear, which is the question regulators increasingly ask.
Government & Conservation
Acoustic density and abundance estimates with stated uncertainty, plus long-term soundscape records for recovery planning and protected-area management.

Technology

Wave physics, applied to marine life

Six capabilities, each grounded in published methods and tested on real field data.

Passive Acoustic Monitoring
Continuous, non-invasive listening with calibrated hydrophones. Nothing is transmitted, so no noise is added.
Signal Processing & Noise
Filtering, spectral analysis and calibrated noise measurement tuned for busy coastal waters, where vessel noise often dominates.
Machine Learning Classification
Neural networks classify calls, whistles and clicks. Published models of this class report high accuracy on their own test sets; we measure precision, recall and false alarms per hour on local recordings before relying on them.
Localization & Array Design
Time-difference-of-arrival localization, drawing on inverse methods from seismic and ultrasonic imaging. We also help design array layouts; a single hydrophone gives presence, not a position.
Coverage & Abundance
Detection probability is measured from the array itself, then combined with established cue-counting methods to estimate density, with uncertainty stated.
Real-Time Data Infrastructure
Streamed detection events, API access and a hosted dashboard, typically within minutes of a call depending on the data feed.

Who We Are

Engineering a future for our oceans

V15ION was founded by a PhD geophysicist with industrial experience in acoustic imaging, fields where pulling faint signals out of noisy wavefields is the daily work. Listening for whales is the same physics: a wave, a medium, an array of sensors, and an inverse problem to solve.

"The ocean is defined by energy, pressure, and sound. As physical scientists, we look past the surface — bridging wave mechanics, signal processing, and marine biology to turn a lifelong passion into precise, scalable technology."

We bring that discipline to marine conservation: calibrated measurements, stated uncertainty, and methods that stand up to scientific review.

Acoustic Engineering
We design monitoring arrays and analysis pipelines that track marine life through complex, noisy soundscapes.
Applied Physics
We model how sound travels through the water to understand how vessel noise, sonar and construction affect marine habitats.
Conservation Technology
We turn acoustic data into timely, usable information for operators, regulators and researchers.

Mission

Conservation and commerce, finally aligned

Protecting endangered marine mammals and enabling safer maritime operations are not competing goals — they are the same goal, solved by the same technology.

  • Passive listening only. V15ION adds zero acoustic energy to the ocean. Our hydrophones listen — they never transmit.

  • Built on published science. Our methods follow peer-reviewed practice, and we report accuracy the way scientists do: precision, recall and false alarms per hour, on local data.

  • Uncertainty, stated. Every estimate we deliver comes with its uncertainty and the assumptions behind it, so you know how far to trust it.
