A method for detecting and locating a carbon dioxide leak in a submarine environment includes operating autonomous underwater vehicles (AUVs) in the submarine environment, where the operating includes obtaining, with each AUV of the AUVs, measurements of an attribute indicative of carbon dioxide, communicating, while operating the AUVs, the measurements from the each AUV to other AUVs of the AUVs, mapping, while operating the autonomous AUVs, carbon dioxide concentration in the submarine environment, and guiding the AUVs toward a highest concentration of the carbon dioxide concentration based on the mapping.

A submersible vehicle for collecting material from a seafloor includes a chassis. A module may be supported on the chassis, the module including an electric power supply. A drive system may be supported on the chassis, the drive system including a battery, and a propulsion assembly, the battery in electrical communication with the electric power supply and the propulsion assembly, and the propulsion assembly operable to locate the chassis relative to a seafloor. A power tool may be coupled to the chassis, the power tool operable to collect material from the seafloor. A reactor may be supported on the chassis, the reactor defining a reaction chamber. A valve assembly may be actuatable to move a hydrogen-containing gas from the reaction chamber and direct the hydrogen-containing gas to one or more of the electric power supply or the power tool.

A docking system has flat funnel and a slotted ramp at the end of the flat funnel. The slotted ramp has a plurality of inclined planes, each on a respective side of the slot. A docking adapter, fitted over an underwater vehicle, includes a guide plane and a mask. The flat funnel guides the guide plane to the top of the ramp during docking, so that the underwater vehicle may be charged. Another aspect of the invention is a highly maneuverable glider including a forwardly mounted buoyancy module followed a pitch module, followed by a processing module, followed by a roll module, mounted concentrically with respect to each other. The glider may be attached to any docking system, not just that of the present invention. When used in conjunction with the docking system of the present invention, the glider may be attached to either the flat funnel or the docking adapter of the docking system of the present invention.

Embodiments include enclosures for protecting electronics such as circuit board and battery assemblies in high-pressure environments. Customized pressure distribution structures are positioned around the electronics. The pressure distribution structures include cavities that are sized to distribute pressure across the electronics in a predetermined manner based on known pressure tolerances of components or portions of the electronics. The pressure distribution structures may include various features such as vias for enhancing thermal conductivity. The enclosure may be sealed and surrounded by an envelope. Methods for manufacturing such enclosures are disclosed.

Disclosed are an automatic stable posture seabed base and a releasing method, belonging to the technical field of ocean observation. The automatic stable posture seabed base includes an accommodating body with an inner cavity for accommodating the first observation device and a seawater, and the accommodating body has first through holes for the seawater to enter and outflow the inner cavity; plugging members blocked at the first through holes to close or semi-close the first through holes; and a buoyancy body installed at a transducer of the first observation device, and a buoyancy of the buoyancy body is larger than a mass of the first observation device, so that the first observation device may float in the cover body after the cover body is filled with water, and a posture of the transducer in the cover body always keeps vertically to the sea surface.
