Radioactive carbon from nuclear bomb tests found in deep ocean trenches

Radioactive carbon released into the atmosphere from 20th-century nuclear bomb tests has reached the deepest parts of the ocean, a new study in AGU’s journal Geophysical Research Letters finds. Crustaceans in deep ocean trenches have incorporated this ‘bomb carbon’ into the molecules that make up their bodies.
