Dust in ice cores leads to new knowledge on the advancement of the ice before the ice age

Working with the ice core ReCap, drilled close to the coast in East Greenland, researchers wondered why the dust particles from the interglacial period -- the warmer period of time between the ice ages -- were several times bigger than the dust particles from the ice age. The research led to the invention of a method able to map the advancement of the glaciers in cold periods and the melting in warmer periods.
