Capabilities, In the Field
Real Clairwave outputs across the world's key waters — each capability, shown working.
Physics-based transmission loss, sonar-performance, and source-level modeling — anywhere on Earth, in near real time and up to 10 days ahead. Range-dependent PE and ray-trace propagation over real bathymetry and forecast sound-speed fields, sonobuoy-field coverage analysis, and hydrophone-validated results — all in one browser-based platform.
Dual-use maritime acoustics — physics-based, hydrophone-validated, deployable anywhere on Earth.

Real Clairwave outputs across the world's key waters — each capability, shown working.
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.
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.
Wales-Heitmeyer spectral model estimates broadband source level per vessel from ship class, speed, length, and draft.
RAM parabolic equation solver with real GEBCO bathymetry computes range-dependent propagation loss per vessel bearing.
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.
Lay DICASS / DIFAR sonobuoy fields and compute detection footprints — signal-excess coverage and optimized layouts over real bathymetry.
Interactive terrain, vessel markers, and volumetric propagation overlays — run in any browser, no install.
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.
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.
AIS-linked source levels decompose the soundscape into individual vessel contributions — who, how much, and why.
Model the acoustic field before a contact arrives. Evaluate sensor placement, speed, and depth scenarios in seconds — not after the fact.
Built on peer-reviewed propagation codes (RAM, Bellhop, OAST) and benchmarked against recorded hydrophone measurements — transparent, reproducible physics you can audit.
The same range-dependent propagation physics — PE and ray-trace transmission loss over real bathymetry and measured/forecast sound-speed fields — underpins both civil ocean-noise assessment and defense maritime acoustics: sonar-performance and detection-range prediction, sonobuoy-field (DICASS / DIFAR) coverage planning, and acoustic situational awareness. Built on open science and benchmarked against recorded hydrophone data, Clairwave runs anywhere on Earth from a browser, with on-premises and air-gapped deployment available.
