Abstract: An underwater cable burial mechanism including a nozzle disposed in front of a plow blade wherein the nozzle is configured to spray a jet of water onto the sea floor in an intended path of the plow blade to bury a cable in the sea floor. In an embodiment, the underwater cable burial mechanism may include two or more straight flow nozzles disposed in front of the plow blade at various angles and heights. In an embodiment, the underwater cable burial mechanism may be a component of an array burial vehicle, the array burial vehicle further including a pump to provide water to the nozzle(s), cable pack to hold a cable array, at least one ski configured to ride along the sea floor, and at least one thruster configured to propel the array burial vehicle along the sea floor.

Abstract: An apparatus for extracting oxygen from sea water in which a plurality of hollow gill members carry on oxygen extracting heme and are positioned within a diffuser. A flow of oxygen bearing liquid, such as sea water, passes through the diffuser and around the gill membranes. The gill membranes are angled with respect to the flow of sea water. The diffuser has a reduced section intake and outlet, and is divided into a number of channels, with the result that the drag force is reduced while maintaining adequate oxygen extraction. Propellers compensate for drag force losses.
