Members of the German research organization GEOMAR Helmholtz Centre for Ocean Research Kiel were on a research expedition looking for deep-sea organisms in the Atlantic Ocean when they stumbled upon natural deposits of the rare earth metal manganese. The mineral accretes over millions of years into nodules that range in size from golf balls to bowling balls. Lead scientist Colin Devey explains the rarity of the find, "Manganese nodules are found in all oceans. But the largest deposits are known to occur in the Pacific. Nodules of this size and density in the Atlantic are not known."
