Team studies beryllium-7 variations over Antarctic regions of the Southern Ocean‎

Beryllium-7 is a radioactive isotope of beryllium produced by cosmic rays in the atmosphere. A Japanese research team has explored, over space and time, how the beryllium-7 is transported from the atmosphere to Earth's surface. Their goal was to better understand the mechanisms of atmospheric mixing on Earth. Their research is published in the Journal of Geophysical Research: Atmospheres on October 14, 2025.
