Scientists Discover Rapid Chages In Earth’s Core
Effects on the magnetic field
In a recent paper published in Nature Geoscience (*), the geophysicist Mioara Mandea from the GFZ German Research Centre for Geosciences, Potsdam and her Danish colleague Nils OLSEN from the National Space Institute/DTU Copenhagen, have shown that motions in the fluid in the Earth's core are changing surprisingly fast, and that this, in turn, effects the magnetic field of our Planet.
Scientists from the Helmholtz Centre GFZ and other institutions are currently involved in the ESA Swarm mission, which will follow on the CHAMP achievements. The Swarm constellation consists of three CHAMP-type satellites, which will measure the Earth's magnetic field even more accurately than before.
