What effect does a deep underwater burst have compared to other bursts?

A deep underwater burst creates unique effects due to its interaction with water and the surrounding environment. The explosion occurs beneath the surface, which limits the visual effects typically associated with surface or aerial bursts. Instead of a dramatic fireball or large mushroom cloud, the deep underwater burst generates a shockwave that propagates through the water and can create a phenomenon known as cavitation, where bubbles form and collapse rapidly.

This type of burst can lead to significant contamination of the surrounding water due to the dispersal of radioactive materials and other debris into the ocean or any body of water. While there may not be as much visual spectacle, the potential for widespread contamination makes this scenario particularly concerning for marine life and ecosystems. Overall, the reduced visual effects are offset by the serious environmental impacts that result from the contaminants released into the water.
