  1. Leon Gosar Seabed abrasion Data source: MzIP

  2. Seabed abrasion is a Pressure as a Physical damage because of: • littoralisation (constructing/activities) • commercial fishing • marine traffic • anchoring • etc. • MSFD Descriptor 6: Sea-floor integrity is at a level that ensures that the structure and functions of the ecosystems are safeguarded and benthic ecosystems, in particular, are not adversely affected. • DMS Deskriptor 6: Neoporečnost morskega dna je na ravni, ki zagotavlja zaščito strukture in funkcije ekosistemov ter preprečuje škodljive vplive zlasti na bentoške ekosisteme. Topic: Seabed abrasion

  3. Shortcomings: Seabed abrasion • Impact on seabed of littoralisation (constructing and activities)

  4. Shortcomings: Seabed abrasion • Impact on seabed of littoralisation (constructing/activities) Data source: MzIP

  5. Shortcomings: Seabed abrasion • Impact on seabed of comercing fishing: • different fishing tools • fish boats routing • seabed area affected by comercing fishing – pressures not known • impacts on benthic habitats is not known • Impact on seabed of marine traffic: • resuspension of sea bottom sediments – pressures and impacts not known

  6. Shortcomings: Seabed abrasion • Impact on seabed of anchoring : • physical damage is not known • impacts on benthic habitats is not known Data source: Ministry of defence

  7. Shortcomings: Seabed abrasion • Impact on seabed of anchoring : • physical damage is not known • impacts on benthic habitats is not known Data source: Ministry of defence

  8. Actions: Seabed abrasion • Monitoring and impact assessment: • Resuspension of sediments and impact assessment on biological processes • Physical changes at sea bottom and impact assessment on biological processes Multibeam sonar scanning Data source: Harpha Sea, d.o.o. Koper

  9. Possible projects: Seabed abrasion • Possible projects: • Establish monitoring of resuspension of sediments and impact assessment on biological communities at sea bottom (natural and anthropogenic) • Determine geo-morfologic characteristics at sea bottom – remote sensing of physical anomalies • Impact assessment of physical anomalies at sea bottom - remote sensing of anomalies caused by marine related activities • Impact assessment of extent and distribution of habitat types and biological communities - remote sensing + field work for biological assessments Multibeam sonar scanning Data source: Harpha Sea, d.o.o. Koper
