REGIONAL COORDINATION

The monitoring of this sub-programme is:  not coordinated.


PURPOSE OF MONITORING (Q4K)

Follow up of progress towards:

Baltic Sea Action Plan​ (BSAP)​ ​ ​​Segments

Hazardous substances
Biodiversity
Maritime activities

​Ecological objectives

​​Concentrations of hazardous substances close to natural levels
Natural landscapes and seascapes
Thriving and balanced commnities of plants and animals
No illegal pollution
Safe maritime traffic without accidental pollution

Marine strategy framework directive (MSFD) ​ ​​DescriptorsD10 Litter
​Criteria (Q5a)

10DC1 The composition, amount and spatial distribution of litter on the coastline, in the surface layer of the water column, and on the seabed, are at levels that do not cause harm to the coastal and marine environment.

Member States shall establish threshold values for these levels through cooperation at Union level, taking into account regional or subregional specificities.

​Features (Q5c)

Other features:
A description of any other features or characteristics typical of or specific to the marine region or subregion.

ASSESSMENT REQUIREMENTS

Monitoring requirements and gaps

Monitoring is to be carried out to fulfill assessment requirements of HELCOM ecological objectives that are specified through HELCOM core indicators. The requirements on monitoring can include number of stations, the sampling frequency and replication. 

Monitoring 
requirements

There is wide experience and data collected on litter in the seafloor and fishing gear/lost fishing nets in the HELCOM area. Seafloor litter collection is integrated to bottom trawling for fish stocks assessment, so therefore the selection of the sampling stations as well as frequency is associated to the casuistic of the species of interest. Finally, information provided from fishing for litter initiatives contributes to the assessment of the quality of the open water. 

​Gaps

National monitoring is ongoing in several Contracting Parties, although no coordinated monitoring programme is in force. 


Adequacy for assessment of GES (Q5d)

Monitoring should provide adequate data and information  to enable the periodic assessment of environmental status, and distance from and progress towards GES as required by MSFD under Article 9 and 11.

​Adequate data?​​Yes
Established methods for assessment?​No
​Adequate understanding of GES?No
Adequate capacity to perform assessments?​No
