The oceans are largely opaque to electromagnetic radiation, and transparent to sound, as is evidenced by the advanced auditory systems of ocean organisms. Oceanographers too are learning how to use sound to sense the ocean environment. This seminar will provide an overview of the many applications of ocean sound to the study of the physics, biology, and geology of the worlds oceans. Examples include acoustic thermometry to monitor ocean climate change, acoustic sensing of ocean internal waves and mixing, acoustic monitoring of seismic activity, and bio-acoustic sensing of marine life.
