Scientists at the Woods Hole Oceanographic Institution (#WHOI) have made a fascinating discovery in the Arctic. They have found that ancient #lava from #BaffinIsland in #Canada's #Arctic Archipelago have highest ratios of #helium-3 (#3He) to helium-4 (#4He). This suggests extremely high levels of 3He in these lavas might come from #Earth's core. This groundbreaking finding could potentially rewrite our understanding of history of ancient elements in center of our planet. https://www.vice.com/en/article/93kgwd/earths-core-appears-to-be-leaking-in-the-arctic-and-scientists-dont-know-why
