Manganese Nodule Study 



Approximately 25 percent of the deep ocean floor is paved 

 with manganese nodules. Where these nodules contain signifi- 

 cant amounts of copper and nickel, they become economically 

 important. Major mining companies and several nations are 

 actively investigating the possibility of mining these deposits. 

 All evidence suggests that a burgeoning new industry is emerg- 

 ing. However, occurrence of these nodules at great depths 

 (greater than 10,000 feet) and beyond the 200-mile limit of 

 any nation introduces legal, technical, and environmental prob- 

 lems. One of the problems, the origin, distribution, and metallic 

 content of the nodules, is the object of field investigations and 

 studies by scientific laboratories and institutions. Technological
