Predictive Underwater Acoustics

Physics-based sonar performance, transmission loss, and source-level modeling — anywhere on Earth, live and up to 10 days ahead. Real bathymetry, forecast sound-speed fields, hydrophone-validated.

Dual-use: civil ocean-noise & defense maritime acoustics — cloud, on-premises, or air-gapped.

How It Works

Clairwave runs a complete underwater-acoustic prediction loop — from contact position and source level, through range-dependent propagation over real bathymetry, to received level and detection footprint — benchmarked against recorded hydrophone data.

📡

AIS Vessel Tracking + Time Machine

Live positions, speed, type, and dimensions for every vessel in view — plus an AIS time machine to scrub back and replay any historical window and run acoustics on past traffic.

🔊

Source Level Model

Wales-Heitmeyer spectral model estimates broadband source level per vessel from ship class, speed, length, and draft.

🌊

PE Transmission Loss

RAM parabolic equation solver with real GEBCO bathymetry computes range-dependent propagation loss per vessel bearing.

🧮

Multi-Solver Engine

Pick the physics for the problem: RAM parabolic equation, Bellhop ray tracing, OAST wavenumber integration, or CUDA GPU solvers — matched to frequency, range, and bathymetry.

📡

Sonobuoy Field Coverage

Lay DICASS / DIFAR sonobuoy fields and compute detection footprints — signal-excess coverage and optimized layouts over real bathymetry.

🗺️

3D Visualization

Interactive terrain, vessel markers, and volumetric propagation overlays — run in any browser, no install.

Predictive — up to 10 days ahead

Clairwave couples 10-day forecast ocean conditions (GIOPS) with vessel transit prediction: draw a track, skew a contact forward in time, and run tomorrow's acoustics today — future position and future sound-speed field, together in one simulation.

Why Not Just Use Hydrophones?

Hydrophones measure total noise. They can't tell you which vessel is responsible, how much noise it would make at a different speed, or what will happen when the next ship arrives.

Per-Vessel Attribution

AIS-linked source levels decompose the soundscape into individual vessel contributions — who, how much, and why.

Predictive, Not Reactive

Model the acoustic field before a contact arrives. Evaluate sensor placement, speed, and depth scenarios in seconds — not after the fact.

Validated, Not Black-Box

Built on peer-reviewed propagation codes (RAM, Bellhop, OAST) and benchmarked against recorded hydrophone measurements — transparent, reproducible physics you can audit.

Use Clairwave from your AI assistant

Clairwave is an open MCP server (Model Context Protocol). Connect it once and Claude, ChatGPT or Grok can run propagation physics, pull sound-speed profiles and seabed parameters, look up live ships and estimate their noise — and hand you a link that opens the result in the platform. No account, no API key.

Connect

Then just ask

Thirteen tools; every location accepts a place name. Each prompt opens pre-filled in the assistant you pick (connect Clairwave there first).

  • “What is the sound speed profile 50 km west of Gibraltar in March, and where is the sonic layer depth?”
  • “How far could a 150 Hz, 170 dB source at 20 m be heard by a receiver at 100 m outside Halifax, bearing 150?”
  • “What ships are within 15 km of the Strait of Hormuz right now, and how loud is the largest one?”
  • “Run a 3D transmission-loss volume at 400 Hz off Vancouver and give me the link.”

Bathymetry, seasonal sound speed, seabed, RAM and Bellhop solvers, live AIS and vessel noise models — each answer carries its run id and a link that opens the run visualized here.
