RIMPAC 2008: Rutgers Glider MCM Operational
SupportPartners: ONR, Metron, WetLabs, and NAVO
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
Glider Specs.Length: 1.5 mHull Diameter: 21.3 cmWeight: 52 kg
Science Bay Specs.Length: 30 cmDiameter: 21.3 cmMax. Payload Weight: 4 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?
3-D Visualization of the Operational Area (Space and Time)
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?)
