This new artificial intelligence application identifies micro-organisms, matter and contaminates from the bottom of lakes, rivers, harbors, streams and any other large bodies of water utilizing conveyor belts with and without embedded microscope slides, watertight containers, high definition lenses, drones, robots, artificial intelligence and machine learning algorithms. The AI application can be used below and above the surface of water. The AI command center utilizes a gorilla glass panel to manipulate by finger or hand to be viewed clearly by the human eye the matter, microbes and contaminates on the glass before and after they have been analyzed by the algorithms and servers.

A dredge head assembly is disclosed. The assembly includes: a shroud having a generally open bottom end and a top end; a screen structure covering the generally open bottom end of the shroud; a suction pipe with a first end connected to the top end of the shroud and a second end configured to be operatively connected with a pump which induces suction; a handle connected to and extending from the shroud and having at least one grasping portion; and one or more vacuum relief valve assemblies, each comprising a valve, at least one opening configured to be in communication with water, and an actuation mechanism positioned to be accessible to a diver. Dredging systems and methods of dredging are also disclosed.

A dredging system for the removal and cleaning of sediment in bays, port entrances, navigable channels, docks, watercourses, lakes or reservoirs, which is provided with means for excavating, dragging and removing the bottom of the waterway and means for regulation and support, the driving force for which is provided from land, which facilitates extraction of sediments directly onto the land, immediately leaving a planar surface on the sea bed. The aforesaid is achieved by controlling the excavator means and very closely controlling the cutting depth, all in a shorter period of time and at lower cost.

Systems and methods for recovering and concentrating rare earth elements from seabed sediment deposits using seabed excavators and shipboard processing systems.

A system and method of off shore mining for retrieval and extraction of heavy mineral concentrate from placer deposits or other suitable materials. The system comprises a dredge vessel and a barge, coupled in conjunction to the dredge vessel. The dredge vessel having thereon a dredging unit, at least one gravity separator and spiral separators for procurement of total heavy minerals from dredged sediment and debris. The barge is configured to acquire and process the total heavy minerals, wherein the barge has thereon at least one magnetic separator, electro-magnetic separators, and density separators for separation of desired minerals based on their physical properties. The system further comprises at least one discharge conduit for tailing of wastes, leftover after extraction and separation of desired minerals, back into water bodies.

A seafloor nodule concentrating system is provided. The seafloor nodule concentrating system has a surface vessel and an undersea steering vehicle secured to the surface vessel. The undersea steering vehicle is adapted to be towed by the surface vessel. The seafloor nodule concentrating system also has a nodule collecting apparatus connected to the undersea steering vehicle. The nodule collecting apparatus is located on the seafloor. The seafloor nodule concentrating system also has a position determination device adapted to determine the position of the nodule collecting apparatus and communicate position information of the nodule collecting apparatus to the undersea steering vehicle and surface vessel.

A floating filtering apparatus is used to separate solid material in a slurry by size, so that the filtered slurry and/or solid material that has been separated from the slurry can be further processed. The floating filtering apparatus comprises a filtering assembly, a first submergible tank, a first pump, and a receptacle for secondary material. The floating filtering system is contained in or supported by a vessel that floats on water and can move and/or be moved about on the surface of the water.
