A buoy position monitoring method includes a buoy positioning step, an unmanned aerial vehicle receiving step and an unmanned aerial vehicle flying step. In the buoy positioning step, a plurality of buoys are put on a water surface. Each of the buoys is capable of sending a detecting signal. Each of the detecting signals is sent periodically and includes a position dataset of each of the buoys. In the unmanned aerial vehicle receiving step, an unmanned aerial vehicle is disposed on an initial position, and the unmanned aerial vehicle receives the detecting signals. In the unmanned aerial vehicle flying step, when at least one of the buoys is lost, the unmanned aerial vehicle flies to a predetermined position to get contact with the at least one buoy that is lost.

The various embodiments herein provide a safety device for anticipating and detecting a potential incident in a water body. The safety device comprises a sensor unit, a processing unit, a data transceiver and a computer readable program. The sensor unit is installed over a surface of the safety device to monitor a human and a water vehicle activity and assess a water condition in a device's vicinity. The processing unit is a core module connected to the sensor unit within a housing to receive, process and transmit a data in a real time. The data transceiver is connected to the processing unit through a bidirectional channel to a monitoring authority. The computer readable program is installed in the safety device and runs over the processing unit. The computer readable program acts as an interface between the safety device and the monitoring authorities.

A weather mitigation assembly for reducing the surface temperature of the ocean to mitigate developing oceanic weather systems includes a buoy that is floated on the ocean. An air pump is coupled to the buoy and a plurality of tethers is each coupled between the buoy and the ocean floor for keeping the buoy in a selected spot. A network of bubble pipes is each laid along the ocean floor. A supply pipe is fluidly coupled between the air pump and the network of bubble pipes. In this way the air pump can pump air into the network of bubble pipes. Each of the bubble pipes releases air bubbles upwardly toward the surface of the ocean urge cool water on the ocean floor upwardly toward the surface of the ocean. In this way the surface of the ocean can be cooled thereby reducing thermal energy available for developing weather systems.

The present invention relates to profiler systems and methods for observing and sensing aspects of a body of water at a plurality of depths. A water profiler is disclosed comprising, generally, a vessel body connected to an external mooring mechanism via an attachment mechanism, a drive mechanism for maneuvering the vessel body longitudinally about the mooring mechanism; an articulating mechanism; and a sensor array capable of measuring a parameter for study wherein the vessel body is capable of articulating about the mooring mechanism. In alternate embodiments, the articulation allows the vessel body to be placed in relation with the three dimensional current such that at least one sensor is positioned into the current so as to sample or measure undisturbed water. In alternate embodiments, hydrofoils or wings are mounted to the vessel body that can be manipulated to harness the current force and maneuver the vessel body.

An underwater positioning system comprises a plurality of underwater beacons. A beacon, in response to a signal sent by an underwater vehicle, responds with a signal comprising one or more characteristics to identify the beacon. Components of an access algorithm are provided to the underwater vehicle. The access algorithm determines a location of the beacon based on the beacon's identity. A position of the vehicle is determined based at least in part on the location of the beacon.

A floating device having active stabilization and a method for actively stabilizing a floating device employs a floating device that operates underwater and which may be tethered to the floor of the body of water. The floating device having active stabilization includes an internal sensor assembly which measures angular velocity and generates a real time output corresponding to a measured angular velocity and a counter-rotation assembly which generates in real time mechanical energy in the form of rotation in response to the real time output of the sensor assembly that causes a counter-rotation torque on the device body that opposes the measured angular velocity. The counter-rotation torque may be imparted by accelerating a flywheel as a reaction wheel in the opposite direction of the desired counter-rotation torque, thereby achieving stability of the device body in the form of minimizing rotation.
