E. A Small Ocean Glider with Far-Reaching Goals

Narrator: This is Science Today. Oceanographer Russ Davis of the Scripps Institution of Oceanography at the University of California, San Diego seemed to turn an early childhood hobby into a scientific career.

Davis: I grew up making model airplanes and now I'm making model airplanes that go under the water.

Narrator: This so-called underwater model airplane that Davis refers to is actually an autonomous underwater vehicle, or AUV, which is called Spray. Davis helped design Spray, which recently made history crossing the Gulf Stream from Massachusetts to Bermuda. Davis says Spray's voyage may some day even benefit national interests.

Davis: I was at a meeting where the Navy is looking into how to use these technologies for measuring what the sound speed profiles are in the ocean to tell what sound propagation is like. To maybe even listening for targets.

Narrator: The current goal is to see if Spray can make a round-trip voyage from Massachusetts to Bermuda. For Science Today, I'm Larissa Branin.
