2002 Technology and Applications of Autonomous Underwater Vehicles  
A class of small (50 kg, 2 m length), reusable autonomous underwater vehicles capable of operating at speeds of 20-30 cm/s with ranges several thousand kilometers and durations of months has been developed and tested. The vehicles, essentially autonomous profiling floats with wings, execute sawtooth patterns between the surface, where they are located and communicate to shore, and depths of O(1000 m). These vehicles are commanded remotely and report results to shore in near real time. Different

These approaches are described and examples of completed scientific missions are given.
