Ocean Infrasound

The ocean continuously radiates infrasound. The ocean processes that produce microseisms on seismometers and hydrophones produce microbaroms in the atmosphere. Breaking ocean waves also produce sound that scales with the breaker height and type. There is also a viable potential to use infrasound as a tool for identifying tsunamigenic earthquakes. What used to be a very specialized field of study (microbaroms) is recently beginning to expand into new oceanographic applications.
