Webb Slocum Glider AUV Technical Achievements

• 10 days autonomous operation
• Over 5,200 CTD casts
• Held position and communicated during storm
• Control switched from Tuckerton, NJ to Falmouth,
  MA
• Navigation tests, with and without current
  correction
• Onboard data processing changed during mission
• Data transmitted to shore every 45 minutes

Conclusions

• Long-range CODAR sensitivities studied and
  coverage optimized.
• Bistatic CODAR concept demonstrated, tests
  ongoing.
• Glider AUVs operated for 10 days, transmitting
  CTD and current
• information.
• Ocean color data accessed from Chinese FY1-C.

• Concerns
• Transition from Research to Operational Support
• Training of a new generation of Operational
  Oceanographers.
