Abstract:

A general expression for the curvature of the ray path in an ocean channel whose water mass is assumed to be moving with a three-dimensional mass velocity decreasing exponentially is derived. Furthermore, the speed of sound is assumed to decrease exponentially with depth. The ray data for the source of various depths of 100, 200, 300, 400, and 500 feet is calculated and presented. The results are compared for a motionless media, and for no horizontal variations of the water mass velocity. Author
