Ever since they were discovered in 1873, scientists have been trying to find out the origin of the millions of potato-sized metal balls that carpet the world's oceans. 

Known as manganese nodules, these lumps contain valuable metals that scientists someday hope to harvest from the sea floor.

Now German scientists could be closer to solving the mystery of their origin after stumbling on the largest patch of manganese nodules ever found in the Atlantic.

The R/V Sonne, a research ship, was several hundred miles east of Barbados when a net meant to capture marine life instead captured manganese ore nodules.

A remote camera later revealed that the seafloor was littered with these metal rocks ranging in size from golf balls to bowling balls.
