1. An air pressurization buoy, comprising:
a buoyant structure adapted to float adjacent to an upper surface of a body of water, and having an inner fluid reservoir;
a hollow tube depending from the buoyant structure, which, when the buoyant structure floats adjacent to an upper surface of a body of water, has an approximately vertical orientation, the hollow tube comprising;
an aperture at a lower end through which water may flow between the body of water and an interior of the hollow tube;
an inflow valve adapted to fluidly connect an interior of the hollow tube to the atmosphere when a pressure of the hollow tube falls below the atmospheric pressure;
an outflow valve adapted to fluidly connect an interior of the hollow tube to the inner fluid reservoir when a pressure of the hollow tube rises above a pressure of the inner fluid reservoir; and
wherein the inner fluid reservoir contains an aperture through which fluid may flow between the inner fluid reservoir and the body of water.
