SeaGlide is a miniature underwater glider designed to be built by high school students. It moves by changing its buoyancy, taking in or expelling water. This change in buoyancy causes the glider to rise and sink in the water. As the glider travels up and down, its wings generate lift, which propels the glider forward.
Full scale underwater gliders deploy for months at a time to collect valuable data about the world’s oceans. SeaGlide can't run for months at a time, but it can collect temperature and pressure data as it flies through the water.
