FREE digital book: DOSITS Book II: Science of Underwater Sound.
An airgun is a tool used to examine layers of the seafloor to study the Earth’s history and locate subsea oil and gas deposits.
Mapping the Seafloor
How is sound used to map the seafloor?
How is sound used to study coral reefs?
Acoustic characterization and monitoring of underwater soundscapes have become a major interest because of the importance of sound to many marine species.
Sounds of hurricanes
Hurricanes (also known as typhoons) can generate a loud sound underwater that can be heard in the local region. The sounds generated by a hurricane have rarely been recorded by a hydrophone.
How does sea ice affect how sound travels?
In regions covered by sea ice, the interaction of sound with the ice affects transmission loss. With changes to Arctic sea ice, its effects on how sound travels can be expected to be significantly different now
Submarine volcanic eruptions
Scientists use underwater acoustics to map, monitor, and evaluate the eruptions of submarine volcanoes.
