• Description of core system• Lessons Learned• Work that Remains

PICO Big Picture: Operations Concept

Concept Test: F/V Sea Falcon

PICO Mooring DiagramStandard:-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

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

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.
