Have We Found Anything Yet?

Have we found anything yet? We sure have! One of the sediment cores contained a manganese nodule that was mixed in with the dark brown sediments. As you can see, the sediments contain a lot of water and the ruler provides a scale for determining size. Manganese nodules form on the seafloor by a very slow precipitation process. The nodules typically have a wide variety of metals in them, such as manganese, copper, cobalt, and others. Much of the Pacific Ocean seafloor is covered by them. One of our co-chief scientists, Steve D’Hondt, believes some areas are almost paved with them. His reasoning is that when you core areas close together, you almost always recover a nodule.
