Nuclear Tests from Cold War Left Bomb Carbon in Deep Sea

The cold war between the United States of America and the Soviet Union saw more than a few nuclear bomb tests in the ocean. Both of the countries were fighting hard in the cold war to establish the authority in nuclear space over the others. According to the new study by the scientists, the nuclear tests done by both the countries between the 1950s and 1960s have left the bomb carbon from the bombs dropped in the sea have settled in the deep sea. The water from the deep sea that the scientists have tested at the laboratories showed the traces of bomb carbon.

According to the tests and the research published in Geophysical research letters, amphipods, the creatures that feed on the microorganisms on the deep sea surface have found the traces of radiocarbon. Although naturally, radiocarbon takes thousands of years to reach down to the deep sea levels, with the sea creatures having access to the deep sea and the surface of the sea, the radiocarbon particles settle down on the deep sea surfaces pretty fast, in this case within 60-70 years.

Geochemists at the Chinese Academy of Sciences performed the tests with the deep sea water in the western Pacific ocean. The traces of radiocarbon, mostly the carbon-14 is found in the deep sea trenches of the Pacific ocean where the majority of the nuclear tests were done. Carbon-14 mostly appears naturally in the water, but the elevated levels suggest that the atomic bomb tests are the reason behind highly increased levels. In terms of the biological system, the surface creatures and deep sea creatures are pretty different, and both are interdependent. Any stupid human activity like nuclear tests can affect the biological system which is 11,000 meters below the sea levels.
