Abstract: An autonomous submersible vessel employs ambient wave energy to both propel itself and to generate required onboard electrical power. The vessel combines a ballast stabilized stator portion and a wave orbit driven rotor portion. Controlled resistance to their relative rotation occurs only when the horizontal component of wave orbit motion coincides with the desired direction of navigation, so increased hydrodynamic drag at that time acts to pull the vessel forward. The vessel incorporates a means to collect and preserve plankton samples. The vessel design enables alternate operation as an oceanographic glider to also navigate in deep water and in calm seas.
