Seagliders are a range of autonomous underwater vehicles (AUV) or underwater gliders developed for continuous, long term measurement of oceanographic parameters. Rather than an electrically driven propeller, these vehicles uses small changes in buoyancy and wings to achieve forward motion. The system's pitch and roll are controlled using adjustable ballast (the vehicle battery).
Presently three different versions are available - see data sheets (below) for details:

Seaglider C2 - Max depth: 200 m
Seaglider - Max depth: 1000 m
Seaglider M6 - Max depth: 6000 m

A Novel Propulsion Method

The vehicle moves through the water in a saw-tooth like pattern and surfaces often to determine its position. Navigation is accomplished using a combination of GPS fixes while on the surface and internal sensors that monitor the vehicle heading, depth and attitude during dives. External sensors are constantly scanning the ocean to determine environmental properties.
