Shallow water propagation incorporating both bubble plumes and sea-surface roughness
The effect of including a range dependent bubble layer and a suitable sea surface spectrum in modeling shallow water propagation is analyzed. Propagation is simulated through a hrghly accurate model based on a modified PE algorithm which handles surface roughness via conformal mapping. The bubble layer rs modeled as a collage of bubble plumes and is included through a complex index of refraction. Propagation at 5 kHz in a 30 m isovelocity waveguide is analyzed in detail.
