Topics
• Description of core system• Lessons Learned• Work that Remains
PICO Big Picture: Operations Concept
Concept Test: F/V Sea Falcon
PICO Mooring Diagram
Standard:-Vaisala WTX-520 (ATRH, Wind,BP, Rain)-Inductive link-Iridium coms
Optional:-Carbon, Tsunami, etc
Prawler :SBE pumped CTDCTD cycle depth ~3-500mRealtime command/control
ETD Deployment Locations to Date
R&D Tsunami Tsunami (DART) R&D Climate (PICO)
Australia-BOMTsunami +realtime MET, SST
Additional spin-offs
• Carbon Buoys (shallow water)• Industry collaboration:– Single continuous composite mooring line (patent)– New commercial low-power SBE CTD– Tech & know how transfer– Shark-bite resistant mooring lines
-Mooring have survived strikes in GOM, Hawaii-Unique bite resistant armor
PMEL Mooring Line Testing
Mooring Line “Prawler” (Profiler+Crawler)

Lessons Learned
• Get “Operations” involved early: Design for Operations...however, x-fer funding usually not included.
• Clear understanding of data “Quality vs Cost”• Discipline of Integration: making wise choices• Spin-offs are valuable developments• Additional tool, not a ‘silver bullet’• Partnerships required
Near Future

Program Sponsors: CPO, NWS Tsunami, OER
Summary:•A multidiscipline, easy-to-deploy platform has been developed that incorporates O&M concerns
•Sensors have been successfully adapted on that can enhance 4D datasets.
•O&M costs are lower compared to using large ships and traditional methods, especially in ‘remote’ areas.
