Decades after the nuclear bomb tests of the Cold War, crustaceans found in the deepest trenches of the Pacific Ocean showed high levels of radioactive carbon in their muscle tissues, a study finds
Crustaceans found in the deepest trenches of the Pacific Ocean showed high levels of radioactive carbon in their muscle tissues, according to a study published in the journal Geophysical Research Letters in April. The"bomb carbon" found its way into their molecules from nuclear tests performed in the 1950s and '60s -- and it's been found miles down into the ocean where these creatures live.
The conditions in these trenches are harsh -- the creatures that live there must adapt to extreme cold, high pressure and a lack of light and nutrients. The crustaceans scavenge and rely on dead organisms that fall to the ocean floor for food. When researchers carbon-dated the crustaceans, they found the levels of carbon-14 in their muscle tissues were a lot higher than the levels of carbon found naturally in the deep ocean.
