Underwater Explosions as Acoustic Sources

1960
Pay-walled Journal Article

Proceedings of the Physical Society

Weston, D. E.,

The manner in which underwater explosions differ from low-amplitude point sources of sound is considered theoretically, especially effects due to cavitation near the sea surface. Some...
