MARIUS: an autonomous underwater vehicle for coastal oceanography

An autonomous underwater vehicle (AW), named MARIUS, has been developed under the MAST Programme of the Commission of the European Communities. The primary envisioned missions of the prototype AW are environmental surveying and oceanographic data acquisition in coastal waters. The authors describe the design and implementation of the AW systems for vehicle and mission control, and report the results of the sea trials conducted with the vehicle in Sines, Portugal.
