The offshore exploration and production (E&P) industry requires comprehensive and accurate ocean acoustic models for determining the exposure of marine life to the high levels of sound used in seismic surveys and other E&P activities. This paper reviews the types of acoustic models most useful for predicting the propagation of undersea noise sources and(More)
We study simulation of underwater communications using acoustic signals impaired by attenuation and multipath propagation. Attenuation is sensitive to the source-receiver separation distance, sound speed profile and signal frequency. Multipath propagation is affected by reflection and refraction due to the environment boundaries, sea surface and seabed, and(More)
