Deep Sea Investment Co.,Ltd Program Description

The deep sea, is the lowest layer in the ocean, existing below the thermocline, at a depth of 1000 fathoms (1800 m) or more.The greatest unexploited mineral resources on earth are on the deep-sea floor, including manganese nodules; cobalt-rich manganese crusts that contain nickel, copper, cobalt, and manganese; and hydrothermal deposits that contain copper, lead, zinc, gold and silver. Deep-sea mineral resources are found in specific areas. Manganese nodules are half-buried in comparatively flat deep-sea sediment at a depth of 4,000-6,000 meters. Cobalt-rich manganese crusts cover the slope or top of seamounts like asphalt at a depth of 800-2,400 meters. Hydrothermal deposits consist of heavy metal sulfides derived from hot water that vented from the seafloor at a depth of 1,500-3,000 meters.
