HELCOM Expert Network on dredging and subsequent depositing operations at sea (EN DREDS)
Dredging and depositing of dredged material have an impact on the marine environment, especially on the integrity of the seafloor and on benthic communities. Hazardous substances released in consequence of dredging activities can also be of concern.
Based on the HELCOM Recommendation 36/2 on the management of dredged material at sea, the HELCOM Expert Network on dredging and subsequent depositing operations at sea (EN DREDS) was initially established in 2017.
The HELCOM Expert Network on dredging and subsequent depositing operations at sea (EN DREDS):
- supports reporting and validation of data on dredging/depositing operations at sea;
- facilitates the work of the Pressure Group in terms of assessment of environmental pressure caused by dredging/depositing operations at sea;
- cooperate with HELCOM Intersessional Network on Benthic Habitats and Biotopes to ensure consistency of data utilized for the assessment of environmental pressure caused by dredging/depositing operations at sea and impact of these activities on benthic communities.
The HELCOM EN DREDS will
- follow up the implementation of HELCOM Recommendation 36/2 including reporting formats and providing suggestions on updates of the documents when it is relevant;
- review and verify the annually reported data on dredging/depositing activities at sea according to HELCOM Recommendations 36/2 and an established verification procedure;
- provide support for the regional consolidated reporting on depositing of dredged material at sea to LC/LP;
- provide methodological support for the development of the HELCOM information resources on dredging/depositing operations at sea (development pending availability of resources);
- guide the assessment of environmental pressures caused by dredging/depositing operations at sea with the use of the agreed methodology and based on reported data;
- suggest further developments of the methodology to assess environmental pressure caused by dredging/depositing operations at sea with the aim to contribute to the work on developing threshold values for the adverse effects of anthropogenic physical disturbance and physical loss;
- contribute to elaboration of measures to reduce physical disturbance and loss caused by dredging/depositing operations;
- implement any other specific tasks related to the expertise of the group by requests of the HELCOM Pressure Group;
- coordinate their activities with corresponding reporting and assessments activities of OSPAR, with the Contracting Parties members to the two RSC serving as a liaison and utilizing information exchange between the secretariats, as well as with ICES and EMODNET.
