Rutgers University(Largely support) • Provided 3-100m Slocum Coastal Electric Gliders to NAVOCEANO • On-site logistical support in case of emergency recoveries/redeployments • Off-site support for NAVOCEANO (glider configurations, science payload sampling, etc.) • QA/QC and dissemination of Inherent Optical Properties (IOPs): • bb(λ): Optical backscatter (470, 532, 660nm) • c(λ): : Optical attenuation (532nm) • NAVOCEANO took the lead on Slocum glider field operations
The Slocum Coastal Electric Glider Science Bay Specs. Length: 30 cm Diameter: 21.3 cm Max. Payload Weight: 4 kg Glider Specs. Length: 1.5 m Hull Diameter: 21.3 cm Weight: 52 kg
Science Payload Sensors(Modular, Swapable) • CTD – hydrography (Temperature, Salinity, Density) • Optical Sensors – • Eco bb3 pucks (blue, green and red light backscattering) • AUVB (green light attenuation)

How Does this Array/Sampling Regime Help Visual the Battlespace?
Glider/Software Issues • Glider Configuration: • Payload configurations: • Instrument specific calibration coefficients for some instruments reside on the glider • Other instruments require application of calibration coefficients on shore and further processing. • Sampling configurations: • Flight controller is heavily burdened with flight, navigation and communication priorities • Glider sampling directives must be fine tuned to achieve optimum data collection. • FUTURE: all science data logged on science controller, which should eliminate many (if not all) of these issues. • Shore-Side Processing: • FTP of raw glider data files to Rutgers • Processing at Rutgers • FTP profile data back to NAVOCEANO/NRL Long data pipelines = lag time between measurement and application of measurement for MCM operations!
Field Issues • Working across 5 timezones – lag between when you want something done and when it is actually done! • Damage as a result of Deployment/Recovery in heavy seas • Final Data Collection (making sure all data is shore-side before wiping flash cards)
What Did We Achieve? • Successful transfer of AUV control from Rutgers University to NAVOCEANO for 24-hour Operations • Successful characterization of the Operational Area using a fleet of AUVs deployed outside the area of interest
Future Recommendations • NAVOCEANO – more deployments, more deployments, more deployments! • Shore-side data QA/QC (NAVOCEANO, NRL?) • Data visualization tools (TWRC, NAVOCEANO, NRL?)
