Deep-Sea Mining versus Land-Based Mining: A Cost Comparison

  • Rolf Dick


During a Pacific voyage of the British Research Vessel “HMS Challenger” in 1876, nodular polymetallic structures containing large amounts of manganese were discovered on the ocean floor. One hundred years later, the planned mining of these manganese nodules became the central topic of debate at the Third UN Law of the Sea Conference. The main points at issue at this conference were the conditions under which deep-sea mining can be carried out1, the organization of the seabed supervisory authorities, the production quotas, the transfer of technology, and the taxation of deep-sea mining2.
