| Mysterious Radioactive Anomaly Discovered Deep Under The Pacific Ocean
Nature
14 February 2025
ByCarly Cassella
A strange radioactive 'blip' has been detected deep beneath the Pacific Ocean.
Analyzing several thin layers of seafloor crust, scientists in Germany have identified a sudden surge in the radioactive isotope Beryllium-10 sometime between 9–12 million years ago.
The beryllium-10 blip was detected in the seabeds of the Central and the Northern Pacific, but the authors behind the study, led by physicist Dominik Koll of the Helmholtz-Zentrum Dresden-Rossendorf research institute, say the anomaly could be present throughout the Pacific, maybe even the world.
It's unknown where the sudden surge came from, but researchers have a few ideas.
Beryllium-10 is a radioactive isotope that is continuously produced by cosmic rays interacting with Earth's atmosphere. When it rains from the atmosphere and settles in the ocean, the isotope becomes incorporated into the extremely slow growth of some deep metal-rich crusts.
