The effects of current on the ray geometry, spreading loss, boundary loss and phase shift, and travel time of individual continuous-wave CW arrivals, as well as the effects on the total acoustic field, are analyzed for three distinct ocean channels one with constant sound speed and spatially uniform current, one with linear depth-dependent sound speed and spatially uniform current, and one with constant sound speed and linear depth-dependent current. When possible, the theory is compared with actual acoustic-field observations. Author
