What would a hydrogen bomb do to the Pacific Ocean?

The explosion would send radioactive particles flying through the air and into the water. Wind could carry the dangerous particles over hundreds of miles.

The smoke from the blast site could block out sunlight and hinder life forms at sea that depend on photosynthesis to survive. The exposure to radiation could cause severe health problems for nearby marine life. Radioactivity is known to damage cells in humans, animals, and plants by causing changes in their genes. The changes could lead to crippling mutations in future generations. The eggs and larvae of marine organisms are especially sensitive to radiation, according to experts. Affected animals could pass the exposure up the food chain.

The test could also have damaging and long-lasting effects on humans and other wildlife if the radioactive fallout reaches land. The particles could contaminate air, soil, and water supply.
