Yellow submarine: Unmanned sub studies ocean

This undated handout photo provided by Rutgers University shows a little yellow remote-controlled submarine in the Atlantic Ocean. "The big advantage is, it's totally unmanned. It's very efficient and can be used to obtain the same kind of data we gather from ships," explained Conrad Lautenbacher, head of the National Oceanic and Atmospheric Administration, a sponsor of the glider developed and operated by Rutgers University.
