A joint team of scientists from the Woods Hole Oceanographic Institution and the California Institute of Technology observed evidence of high levels of helium-three in rocks on Baffin Island—potential evidence that the Earth's core is leaking. In their paper published in the journal Nature, the organization describes their observations of helium-3 and helium-4 in the Canadian Arctic Archipelago.

Early researchers saw helium-3 elements in lava flows on Baffin Island, suggesting a possible leak from the Earth's core. This is due to the fact that it is an old isotope - it changed conditions over time as the Earth formed and was trapped in the core. But due to its nature, helium-3 that makes its way to the ground quickly escapes into the atmosphere and disappears into space. Thus, helium-three is rare. If it is found on the surface, the percentage is high enough that it has made its way out of the centre.

Intrigued by the possibility that the Earth's core might be leaking, the research team went to Baffin Island and began monitoring the massive lava flow. They observed higher levels of helium—three times higher than those found in previous studies—higher than anywhere else in the world. They also found high levels of helium-3 in helium-four (a rare isotope) - the best ever measured in Earth's rocks. Such extreme estimates, the researchers suggest, are everything that suggests that helium-three comes from the core.

The research team notes that locating such high levels of helium-3 at a terrestrial web site is a large deal, because if it can be proved that the fabric is indeed leaking from the middle, it will provide scientists with a way to take a look at core cloth, which has in no way been completed earlier than. That could screen extra approximately the middle than previously notion feasible. They observe that if the helium-3 is coming from the centre, then the alternative fabric round it needs to be as well, offering similarly bodily examples of centre fabric.
