  4. AC9 AC9 Biofouling Sediments Optical background NEMO Site Selection Activity > 25 sea campaigns since 1998 • light transmission propertiesof deep sea water(AC9 transmissometer) • optical background(custom devices) • deep sea currents(RCM11 and RCM8 current metre) data analysisOGS • nature and quantity ofsedimenting material(Sediment trap) dataanalysis IBM • seabedcharacteristics (cores and bottom profile) dataanalysis CEOM-ENI Other sites explored Lake Baikal, in collaboration with BAIKALsite evaluation group Toulon(ANTARES site), in collaboration withANTARESsite evaluation group V. Balkanov et al. NIM 2002 KM3NeT kickoff meeting

  5. Oceanographic data measured in Capo Passero Two current metres and a sediment trap are moored in Capo Passero Region since 1998. Current metre 2900 m Sediment trap 3000 m Current meter 3050 m Seabed 3350 m KM3NeT kickoff meeting

  6. Capo Passero: sedimentation rate Etna eruption July 2001 KM3NeT kickoff meeting Sediment samples collected over more than 3full years: Aug 1999-May 2000 and July-December 2001(analysed). Other periods under analysis
