ABSTRACT:
A method and apparatus for harvesting the ocean floor is disclosed. A sled connected to a vessel is towed over the ocean floor. The sled is supported by spaced apart runners that mount an upwardly open container in which particles to be harvested are collected as the sled is drawn forwardly by the vessel. A cable extends from the vessel to the container and is driven in a forward direction. Buckets are mounted to the cable and have a forwardly directed open end. The cable is guided so that the buckets are moved through the container of the sled to thereby pick up the particles and convey them to the vessel. The sled includes means for dislodging the particles to be harvested from the ocean floor, and for separating from the particles silt and other undesirable contaminants of a size smaller than the particles.
