Abstract
A variable buoyancy device has an inner region and an outer cavity. The outer cavity extends at least partially around the inner region and is adapted to contain fluids, such as a liquid and a gas, the relative proportions of which can be varied to vary buoyancy. The inner region provides an advantageous location for equipment, while the outer cavity provides a significant volume for achieving a wide range of buoyancy adjustments.
