Ferromanganese crusts record past climates

The onset of northern hemispheric glaciation cycles three million years ago has dramatically changed Arctic climate. Scientists of the GEOMAR Helmholtz Centre for Ocean Research Kiel, Germany have now for the first time reconstructed the history of Arctic climate based on records archived in ferromanganese crusts. The study, a collaboration with the United States Geological Survey and the Swiss Federal Institute of Technology Zurich, has now been published in the journal Earth and Planetary Science Letters.
