 BELLHOP gaussian beam/finite element beam code
(M. Porter, Heat, Light, and Sound Research ,Inc.)

(updated 21 May 2008; BELLHOP now allows a range-dependent SSP)
Description of BELLHOP algorithm
General Description (A brief user's guide) (O. Rodríguez, University of Algarve)

 HARPO --- A 3D ray-tracing program for acoustic waves in the ocean
(R.M. Jones, J.P. Riley, T.M. Georges, National Oceanic and Atmospheric Administration)

 Ray (v.1.47) (J. Bowlin/Woods Hole Oceanographic Institution)
This code is apparently used by quite a few people but nobody is actively developing it further.
The master copy is from Arthur Newhall/WHOI.

 Ray tracing for Ocean Acoustic Tomography (Brian Dushaw/APL-Univ. Wash. and John Colosi/WHOI).
Describes a Fortran ray model which follows closely the Bowlin ray code (written in C).
