Seabed abrasion

Data source: MzIP


Topic seabed abrasion

  • 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


Shortcomings:

Seabed abrasion

  • Impact on seabed of littoralisation (constructing and activities)


Shortcomings:

Seabed abrasion

  • Impact on seabed of littoralisation (constructing/activities)

Data source: MzIP


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


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


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


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

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
