  1. 8 floors 8 m bars, vertical dist. = 40 m, Htot = 450 m 32 OM, 18 hydrophones oceanographic instruments 4 OMs/floor 2 hydrophones The NEMO-Phase2 tower elements Final validation of the DU for Capo Passero The OM: 10” Hamamatsu R7081, Front End Module, Time Calibration, LED beacons Hydrophones: acoustic positioning and bioacustics 32 OMs, all fully tested and calibrated. 2 OMs equipped with piezo-hydrophones Erlangen, June 22-23, 2012 Antonio Capone

  2. Mechanical structure, including anchor and deployment tools ready at LNS All “offshore” electronic cards integrated and tested in their vessels, ready at LNS All “on-shore” electronic cards integrated and tested, ready at LNS Nemo-Phase 2 Status The Data Acquisition software ready, will be tested during July/August at Catania lab. All cables/connectors ready at LNS The Power Feeding system, the MEOC, the Junction Box ready at Capo Passero Erlangen, June 22-23, 2012 Antonio Capone

  3. Attività prevista (Luglio-prima settimana settembre) • Questa settimana • Test FCM, chiusura vessel di piano, test Vessel su camera iperbarica • integrazione backbone , break out e PMT su struttura meccanica • Integrazionepiani: • Si parte dal piano piu’ vicinoalla base • -collegamento OM-FCM • -collegamento FCM-break out di piano • -test con 4 OM oscuratisimile a quello di fase 1 (acquisizione fondo PMT, • misura margine ottico, ….. • -si passa al piano successivo • Test finale • Effettuato oscurando tutta la struttura come se la torre fosse in mare • Si utilizza tutta la on shoreelectronics

  4. - Trigger System Controller(TSC): monitors and serves the TriDAS - (1 GbE I/O) (to be finalized) • - Hit Managers (HM): receive optical data; prepare and distribute the Time Slice (TS) to the TCPU (DONE) • - TriggerCPUs (TCPU): apply the trigger logics to the assigned TS and transfer the selected data to the EM; • note: more than 1 TCPU process can run on a TCPU server (Quasi done: TriggerAlgos to be finalized) • - Event Manager(EM): receives the triggered data from TCPUs and build the Post-Trigger events data file (Started) 32 MBps sector 32 MBps NEED OF NEW SERVERS FOR THE Test Bench IN BOLOGNA

  5. Minilinea ANTARES per Capo Passero Provata la settimana scorsa dopo 1.5 anni di stop

  6. configurazione in via di definizione SJB#1 8 Outputs Capo Passero Termination Frame SJB#2 8 Outputs Primary JB STRING AND/OR TOWER SJB#3 8 Outputs • Capabilities: • 20 Optical Fibers G 655 • 10kV/375V DC-DC converter • up to 8.8 KW available off shore • 50 kW available onshore SJB#4 8 Outputs

  7. SEA operations – June 2012 Short summary report R. Papaleo 22 june 2012

  8. Scope of work Deploy SN1 underwater station and connect to TSN termination frame Deploy LIDO acoustic station and connect to NEMO JB Option: Make a visual inspection of the NEMO Mechanical Tower deployed 2 years ago

  9. The Catania Test Site: a multidisciplinarydeepsea-lab LIDO demo mission of ESONET-EMSO: Refurbishment of SN1 and OnDEobservatories Goals: Bioacoustics, oceanmonitoring,Tsunamiwarning. LNS-INFN Catania North Branch (SN1) 4 LBW hydrophones 2 LF hydrophones CTD, ADCP, Seismometers magnetometers pressure gauges GPS time stamping 100 Mbps Internet Radio Link 5 km 20 km 5 km NEMO JB South Branch (Onde2) 4 LBW hydrophones Underwater GPS time stamping LNS Test Site Laboratory at the port of Catania Infrastructure requested by UCL and CSIC for installation of deep-sea stations in 2013

  10. SN1 (TSN) installation and connection: 8 June 2012 MODUS Shuttle power failure. SN1 released 250 above seabed (1850 m). SN1 fallen upside down on the seabed SN1 deployed with the MODUS Shuttle (INGV standard operation) ROV and Certamen C/L Vessel joint operation: SN1 hooked and turned correctly above the seabed SN1 connected to the TSN cable termination. Switch on.

  11. First data from SN1 Hydrophones data Seismometer data Acoustic event, detected by SN1 hydrophones, acquired in time coincidence with a seismic event detected by INGV (June 15th, 6:28 UTC with GURALP seismometer) with intensity 3.8 M.

  12. OnDE 2 (TSS) a full NEMO Phase II floor • Mechanical vessel and interfaces • Cabling • Power Control and feeding System • DWDM optical data transmission system • Floor Control Module main board • Acoustic Boards • Compass • All electronics is sucessfully working • Underwater GPS data time stamping OK • Optical attenuationof the line • (including JB) 12 dB • Heading -8.5° North • Hydrophone data under analysis

  13. ONDE • Stato attuale: • il segnale dei 4 idrofoni e’ ‘affogato’ nel rumore. • Causa probabile: • Modifiche effettuate per estendere la banda verso • basse frequenze( 20 Hz) x terremoti e balene. • Soluzioni possibili • svolgimento cavo connessione • bypassare la JB

  14. Scope of work of the mechanicaltower Check deployment and releaseprocedures OK OK Check unfurlingprocedures Check behaviourof the towerafter the unfurlingprocedures OK

  15. dyneema dyneema BASE RECUPERABILE CATENA ANCORA

  16. Prossime Operazioni • Test operatività ROV a 3500 m previsto per seconda metà luglio • Deployment e connessione torre a Capo Passero previsto a settembre • Compatibilmente con la slot temporale disponibile ,si cercherà anche di intervenire sul sistema acustico (ONDE)
