  1. Data standardisation and seafloor monitoring system interoperability: a further step toward the European seafloor multidisciplinary monitoring network Laura Beranzoli Istituto Nazionale di Geofisica e Vulcanologia

  2. Arctic Norwegian Margin Nordic Sea Porcupine Ligurian Sea Black Sea Marmara Azores Hellenic Eastern Sicily Iberian Margin ESONET EC Concerted Action (2002-2004) EC Network of Excellence (2007-2011) GOALS: Geohazards Global change Biodiversity ESONET

  3. LIDO- LIstening the Deep OceanESONET Demonstration Mission The objective of the proposal will be achieved through the extension of the present capabilities of the observatories working in the ESONET key-sites of • Eastern Sicily (NEMO-SN1) • Gulf of Cadiz (GEOSTAR in the NEAREST pilot experiment) by installing not-already-included sensor equipments related to Bioacoustics and Geohazards;

  4. Optical sensors Electronic vessels NEMO-SN1: The first real-time seafloor observatory of ESONET Established on the basis of an agreement between two major Italian research institutions: Istituto Nazionale di Fisica Nucleare (INFN) Istituto Nazionale di Geofisica e Vulcanologia (INGV).

  5. NEMO-SN1 Observatory layout

  6. Tyrrhenian Sea Ionian Sea Etna Calabria SN-1 Deep Ionian Basin Malta Escarpment Contribution to the seismicity knowledge earthquakes recorded only by SN-1 Sgroi et al., Geophys. J. Int., 2007

  7. SN-1 Background seismic noise Pressure Waves (wind) Micro- seismic band Infra-gravity waves noise notch Short period band ZSN1 (black) VAE (grey) The seismometer recordings at seafloor can be affected by noise induced by sea water circulation A three component single-point current-meter, with high sampling rate, is needed to assess the noise induced Before Etna eruption Noise in high and low sea current velocity (N-S component) Monna et al., Geophys. Res. Lett., 2005

  8. Earthquake recorded by SN-1 Sumatra September 12, 2007 – MW = 7.9

  9. NEARESTPilot Experiment: Gulf of Cadiz Highly populated and prone to devastating earthquakes and tsunamis (e.g., 1755 Lisbon earthquake) More than ten years of geological and geophysical investigations off SW Iberia (multibeam bathymetry, side-scan sonar, high-resolution and multichannel seismics, and sampling which probed the first kilometres of the upper crust at various resolution) Recognition and mapping of active tectonic structures likely to generate large earthquakes and tsunamis.

  10. LIDO – Scientific and Technological Objectives • improving the real-time and near-real-time detection of signals by a multiparameter seafloor observatory network at regional scale for the characterisation of potential tsunamigenic sources • allow real-time and near-real-time long-term acoustic monitoring of marine mammals at regional level, as well as noise propagation • development of the first nucleus of a regional multiparameter seafloor network of homogeneous observatories

  11. EC Projects GEOSTARGEophysical and Oceanographic STation for Abyssal Research 1995-2001 Beranzoli et al., PEPI, 1998; Beranzoli, Favali & Smriglio (eds.), Dev. Mar. Tech., 12, Elsevier, 2002

  12. LIDO – WP 2 Data Management • the data stream from Eastern Sicily and Gulf of Cadiz Observatory sites will be integrated into a common data acquisition and distribution service. 1. Proposal for a contribution to ANTARES Demo Mission: To include in the workplan an activity to achieve the data integration of ANTARES-DM and LIDO with in the same distribution service

  13. 2. Proposal for a contribution to ANTARES Demo Mission: To perform an experiment of acoustic communication with a novel modem and protocol between ANTARES and a remote seafloor module. The seafloor module could be developed within Italian regional technological and reseach projects.

  14. T IL07 Or SJB? Remote Seafloor module • Possible configurations: • One way: using one of the IL07 hydrophone properly configured • Two-way: installing on IL07 a twin modem like the one on the remote module

  17. Contribution to the expected impact of ESONET • to demonstrate the viability of the integration of existing infrastructures • to demonstrate the European capabilities of using a network of underwater observatories by implementing the first regional nucleus of multidisciplinary seafloor observatories in the Mediterranean Sea and the adjacent Atlantic
