Presentation Transcript


  1. ALOHA Cabled Observatory • Will use components from the earlier ALOHA-MARS Mooring project at APL-UW • Seafloor secondary node • Bottom instrument package with science isntrument interface module (SIIM) and sensors (CTDO2, BB2F) • Cables and connectors • Underwater video camera

  2. ALOHA-MARS Mooring • Implemented only on short scale – 30 m high in Puget Sound • For ACO – use seafloor secondary node and bottom instrument package • And cables Bottom instrument package Bottom instrument package Secondary node

  3. Seafloor bottom instrument package • Here set up to goat base of mooring, on mooring line

  4. AMM Secondary seafloor node • Test tank at MBARI • Orange is syntactic foam to make near neutrally buoyant to facilitate ROV moving it on seafloor • 5 ROV-mate Receptacle cables

  5. AMM Secondary node and SIIM • Without syntactic foam (simple deployment Puget Sound • Bottom instrument package/SIIM hard connected behind

  6. Bottom instrument package • SIIM (left) • 2 CTDO2 • 1 BB2f fluorometer/backscatter (black unit) • Syntactic foam to get near neutral buoyancy • Green Falmut cable connecting to secondary node

  7. Science Instrument Interface Module (SIIM) • 8 channels for sensors • Industrial ethernet • One ROV plug cable • Titanium pressure case 6000 m

  8. Electro-optical (EO) converters • For seafloor cable, 1.5 km here (black) • Converts electrical Ethernet to optical for long run, and back • Runs off 48 V from local node • Has a ROV-mate plug cable at each end
