2012-12-11With the location of a suitable mining site, the ocean floor is ready to be harvested. Two technologies being considered for commercial mining of the ocean floor are continuous line bucket system CLB and hydraulic suction systems. CLB is the preferred method and transfers the mud up to the ship in a conveyor belt type system
