18 Σεπ 2020 · The sound speed minimum in the ocean acts as an acoustic waveguide. Many different sources can generate acoustic waves. These include explosions, earthquakes, or perhaps even whale song. Rays emanating from the source at different angles cycle between different depths on their way to the receiver.
Understanding Ocean Acoustics emphasises such applications and issues relevant to studies of the ocean environment and aquatic life. Its focus is therefore environmental research and development using low frequencies relevant to fish and sea mammals.
The depths of the ocean can be a dark and noisy place. While the darkness can make it difficult to extract visual information, the noise can be used to help us learn more about the ocean’s physical structure. UVic professor emeritus Ross Chapman has dedicated his career to developing methods to turn noise into information and put it to good use.
