SOFAR Sound Channel Ray Refraction Calculator
Deep ocean acoustics: Compute Snell’s law sound speed gradient ($dc/dz$), ray curvature radius, acoustic ray turning depths ($z_{\text{turn}}$), and SOFAR channel cycle skip distance.
SOFAR Channel Sound Speed Axis
Depth of minimum sound speed (typically ~1000 m)
Sound speed at channel axis
Thermocline cooling: negative dc/dz
Hydrostatic pressure: positive dc/dz (~0.017 s⁻¹)
Acoustic Ray Source Launch Parameters
Acoustic emitter launch depth
Angle relative to horizontal (0° = horizontal)
