SONAR: Sub-Oceanic Networked Acoustic Resonance

SONAR is an ambitious project to create a live, interactive soundscape and concert from the deepest, most hostile environment on Earth: the hydrothermal vent fields of the Juan de Fuca Ridge. A fleet of custom hydrophones will be deployed by a remotely operated vehicle (ROV) at depths exceeding 4,000 meters, capturing the hiss of superheated water, the crackle of mineral deposits, and the occasional whale song. A second ROV will be transformed into a musical instrument—its manipulator arm tapping and rattling against vent chimneys, its thrusters humming in F#. On the surface ship, musicians (didgeridoo, cello, modular synth) will improvise alongside the live subsea feed, mixed in real time with Ableton Live and Max/MSP. The entire performance will be broadcast via satellite as a continuous webcast. Critically, the project partners with the Makah Tribe, whose traditional knowledge of ocean currents and whale migration routes will guide the site selection and whose water songs will be woven into the mix. For accessibility, a tactile bench equipped with Buttkicker transducers will allow deaf audience members to feel the low-frequency vibrations of the ocean floor. All equipment designs will be open-sourced to enable similar projects.

The deep ocean is humanity's most acoustic frontier, yet we have almost no real-time, immersive experience of its soundscape. Existing recordings are static, often done by oceanographers for science, not art. Meanwhile, indigenous coastal communities have centuries of water-based sonic traditions that are largely absent from contemporary experimental music. There is no live music performance from the deep sea—because it's technically brutal and logistically insane. This project scratches the itch to connect audiences directly with an alien, sublime environment, while centering indigenous voices and ensuring accessibility for the deaf community.

• Deploy six custom hydrophones at 4,000m depth on the Juan de Fuca Ridge for continuous live audio capture.
• Secure a co-creation agreement with the Makah Tribe, incorporating their water songs into the performance and giving them editorial control over their cultural material.
• Develop a tactile listening bench that translates subsonic and low-frequency ocean sounds into physical vibrations for deaf and hard-of-hearing audiences.
• Stage a 24-hour live-streamed concert from a surface ship, with musicians playing along to the subsea feed, and the ROV performing as an instrument.
• Release an album of three curated one-hour mixes from the live streams, with proceeds shared with the Makah Tribe.
• Publish complete technical blueprints for hydrophone arrays, waterproof electronics, and tactile playback systems.

• Not a scientific expedition—no oceanographic data collection beyond what's needed for the sound project.
• Not a commercial venture—no advertising, sponsorships, or pay-per-view.
• No permanent installations—gear will be recovered after the performance.
• Not a one-off event—the project is designed to be an annual series, with new locations and collaborators each year.
• No exclusion of amateur musicians—the surface ensemble will include both professionals and community members from the Makah Tribe.

Hydrophones: Sound Devices 3D-shaped omni hydrophones (rated to 6000m) + custom low-noise preamps with 20Hz-20kHz range. ROV: VideoRay Pro 4 with manipulator arm and additional contact mics bolted to its frame. Contact mics: C-Ducer seismic pickups for tapping vents. Surface mixing: Ableton Live 11 and Max/MSP 8 on a ruggedized laptop, with satellite uplink via Iridium Certus. Tactile bench: Buttkicker Gamer 2 transducers driven by a Crown XLS 2502 amp, embedded in a 4-seat wooden bench. Power: Lithium-ion batteries (48V, 100Ah) + methanol fuel cells for the ship. All electronics housed in oil-filled enclosures for pressure compensation.

The system has two physical stages: the subsea array and the surface performance ship.

Subsea: Six hydrophones are placed in a hexagon ~100m apart around a vent field by the ROV. The ROV itself stays on site, piloting to tap vents with its arm, creating percussive sounds. Hydrophone signals are digitized (24-bit/96kHz) in pressure-tolerant housings and sent up a fiber-optic tether to the ship.

Surface: The ship's onboard mixing station receives all six channels plus the ROV's contact mics. Musicians play in a soundproofed room listening to a mix of the subsea feed; their instruments are miked and mixed back in. The master mix is spatialized (6.1 surround) for on-ship audiences and downmixed to stereo for streaming. The tactile bench receives a separate subwoofer feed (0-80Hz) with heavy compression for vibration feel.

Software chain: Max/MSP runs the spatialization and an 'ocean randomizer' that modulates reverb and delay times based on current pressure readings. Ableton Live acts as the main DAW for recording and mixing. The satellite stream is encoded via OBS Studio at 1080p/96kbps audio (Opus).

• Equipment failure from extreme pressure (400 atm) or hydrothermal temperatures (up to 400°C near vents). Mitigation: pressure-test all cases to 600 atm; use titanium housings for hot zones.
• Communication latency: 1-2 second delay from deep to surface. Mitigation: musicians monitor the direct subsea feed with a metronome synced to shipboard GPS time; the surface mix is delayed to match for streaming.
• Permitting delays: NOAA, tribal, and international waters. Mitigation: start permit process 18 months in advance; hire a full-time regulatory consultant.
• Cultural appropriation accusations. Mitigation: full co-authorship contract with Makah Tribe, veto power over any use of their songs, and 50% of all revenue from sound recordings.

• Can the ROV's manipulator arm maintain precise rhythm while dealing with unpredictable vent thermals? Might require a custom 'drumming' algorithm.
• How to handle the extreme heat of the vent chimneys: contact mics will melt. We're considering sacrificial sensors that last only a few minutes.
• Is satellite bandwidth enough for 6-channel high-res audio plus video? Tests with Iridium Certus show ~700kbps uplink—enough for 6 channels of 96kbps Opus, but video may need to be low-res.
• How to ensure the Makah Tribe feels genuine ownership—should we have a tribal elder as co-producer with equal say on artistic direction?
• The tactile bench: what frequencies are most meaningful for deaf participants? We'll run a workshop with the local deaf community before the build.

The project got through feasibility studies and even built a prototype hydrophone array, but the lead engineer took a faculty position in a different field, and the NSF grant we were counting on shifted priorities. The tribal partnership was nearly finalized, but new regulations required additional environmental impact statements we couldn't fund. It remains a beautiful plan on the shelf—maybe one day.

The hydrophone prototype is currently sitting in a lab at the University of Washington. Some of the tactile research was repurposed for an art installation at the Smithsonian. I still get emails from people who want to help. If you have a submersible and a dream, call me.
