Proposed location but vibrations from glider
contaminated acoustic signals

• June 06 URI visits Rutgers with hydrophone
• August 06 Hydrophone attached to glider for 15
  minute segment
• Sept. 06 Hydrophone attached to glider for 14
  day mission
• April 07 URI visits Rutgers for two days of
  experiments to test beam forming capability

Final configuration with hydrophone towed behind
glider with no rigid connection between the two

• Conclusions
• Glider Development Accelerated through NOPP-style
  Partnerships
• Gliders are now being flown worldwide supporting
  science operations
• Gliders are now being used as an educational tool
  at the undergraduate level
