In accordance with the advice given in Guidance 14 (Walmsley, S.F., Weiss, A., Claussen, U., Connor, D. 2017 Guidance for Assessments Under Article 8 of the Marine Strategy Framework Directive, Integration of assessment results. ABPmer Report No R.2733, produced for the European Commission, DG Environment, February 2017) no threshold is to be specified for D7C1: the status of the D7C1 criterion is therefore not reported. However, the assessment of the D7C1 criterion has provided a first estimate of the exposure indices for spatial areas potentially affected by a change in the current, tidal, wave, bottom nature, turbidity, salinity and thermal regime. Indeed, the results show that the pressures associated with a change in the current, tidal and wave regime do not affect the MRU-L200 (0% of the total area of the MRU). Pressures related to a change in bottom nature and turbidity regime potentially affect a very large area (96.5% of the MRU). It should also be noted that the exposure index calculated for the change in background nature is exclusively low. Finally, the pressures associated with a change in the thermal and salinity regime affect less than 1% of the MRU.

On the other hand, no threshold has been defined so far for the parameter "Extent" and therefore the status of D7C2 is not reported, but the assessment of D7C2 has provided a first estimate of the spatial extent of benthic habitats potentially subject to cumulative risks of alteration, based on the indices of exposure to hydrographic pressures generated by human activities. Thus, 45% of the area of "offshore circalittoral mud" habitat appears to be at medium risk and 55% at low risk.

In the absence of a threshold for the "Extent" parameter, the state of the habitat could not be provided. Furthermore, according to Decision 2017/848/EU, the results of the assessment of criterion D7C2 (estimated extent of adverse effects by habitat type in each assessment area) are used for the assessment of criterion D6C5. However, in the absence of an operational indicator at the level of Descriptor 6 - Benthic Habitats, these results could not be taken into account in the assessment of D6C5.

Description overall status
The assessment of D7, based on data on anthropogenic activities, highlighted significant variations in exposure to pressures:1/ The L200 zone is less subject than the coastal zone (MEC DCE) to exposure to the hydrographic pressures considered.2/ The modification pressures of "turbidity" and "bottom nature" present the largest potential areas of exposure (100% of the Celtic Sea marine sub-region). However, the exposure index remains mostly low, and for 90% of the major benthic habitat types, the area of habitat potentially subject to a medium to high risk of modification is greater than 30% of the total area of habitat, as a result of cumulative exposure to hydrographic pressures. Finally, it is important to specify that the incompleteness and uncertainties associated with the input data, as well as the use of expert opinion and subjective decision rules, imply a significant propagation of uncertainty throughout the treatment carried out. The results should therefore be taken with caution.

In accordance with the advice given in Guidance 14 (Walmsley, S.F., Weiss, A., Claussen, U., Connor, D. 2017 Guidance for Assessments Under Article 8 of the Marine Strategy Framework Directive, Integration of assessment results. ABPmer Report No R.2733, produced for the European Commission, DG Environment, February 2017) no threshold is to be specified for D7C1: the status of the D7C1 criterion is therefore not reported. However, the assessment of the D7C1 criterion has provided a first estimate of the exposure indices for spatial areas potentially affected by a change in the current, tidal, wave, bottom nature, turbidity, salinity and thermal regime. Indeed, the results show that the pressures linked to a change in the current, tidal and wave regime are relatively low (< 2% of the Celtic Sea marine sub-region) and fairly localised since they affect only coastal waters. It should also be noted that the exposure indices calculated for these pressures are mostly low. Pressures linked to a change in the nature of the bottom and turbidity regime potentially affect a very large area (100% of the MRU) although the exposure indices calculated for these pressures are mostly low (respectively >98% of the MRU and nearly 93% of the MRU). Finally, pressures related to a change in the thermal and salinity regime affect less than 1% of the MRU.

On the other hand, no threshold has been defined so far for the parameter "Extent" and therefore the status of D7C2 is not reported, but the assessment of D7C2 has provided a first estimate of the spatial extent of benthic habitats potentially subject to cumulative risks of alteration, based on the indices of exposure to hydrographic pressures generated by human activities. For example, the "Subtidal coarse sediment" habitat presents a high risk area of 8% of the total habitat area.

In the absence of a threshold for the "Extent" parameter, the state of the habitat could not be provided. Furthermore, according to Decision 2017/848/EU, the results of the assessment of criterion D7C2 (estimated extent of adverse effects by habitat type in each assessment area) are used for the assessment of criterion D6C5. However, in the absence of an operational indicator at the level of Descriptor 6 - Benthic Habitats, these results could not be taken into account in the assessment of D6C5.

Description overall status
The assessment of D7, based on data on anthropogenic activities, has highlighted significant variations in exposure to pressures:1/ The coastal zone is the most subject to exposure to the hydrographic pressures under consideration.2/ The modification pressures of "turbidity" and "bottom nature" present the largest potential areas of exposure (100% of the Celtic Sea marine sub-region). However, the exposure index remains mostly low, and for 90% of the major benthic habitat types, the area of habitat potentially subject to a medium to high risk of modification is greater than 30% of the total area of habitat, as a result of cumulative exposure to hydrographic pressures. Finally, it is important to specify that the incompleteness and uncertainties associated with the input data, as well as the use of expert opinion and subjective decision rules, imply a significant propagation of uncertainty throughout the treatment carried out. The results should therefore be taken with caution.

The assessment of D7, based on data on anthropogenic activities, has highlighted significant variations in exposure to pressures:1/ The coastal zone is the most subject to exposure to the hydrographic pressures under consideration.2/ The modification pressures of "turbidity" and "bottom nature" present the largest potential areas of exposure (100% of the Celtic Sea marine sub-region). However, the exposure index remains mostly low, and for 90% of the major benthic habitat types, the area of habitat potentially subject to a medium to high risk of modification is greater than 30% of the total area of habitat, as a result of cumulative exposure to hydrographic pressures. Finally, it is important to specify that the incompleteness and uncertainties associated with the input data, as well as the use of expert opinion and subjective decision rules, imply a significant propagation of uncertainty throughout the treatment carried out.

In accordance with the advice given in Guidance 14 (Walmsley, S.F., Weiss, A., Claussen, U., Connor, D. 2017 Guidance for Assessments Under Article 8 of the Marine Strategy Framework Directive, Integration of assessment results. ABPmer Report No R.2733, produced for the European Commission, DG Environment, February 2017) no threshold is to be specified for D7C1: the status of the D7C1 criterion is therefore not reported. However, the assessment of the D7C1 criterion has provided a first estimate of the exposure indices for spatial areas potentially affected by a change in the current, tidal, wave, bottom nature, turbidity, salinity and thermal regime. Indeed, the results show that the pressures associated with a change in the current, tidal and wave regime do not affect MRU-Z200 (0% of the total area of the MRU). Pressures related to a change in bottom nature and turbidity regime potentially affect a very large area (100% of the MRU). It should also be noted that the exposure index calculated for these pressures is exclusively low. Finally, pressures related to a change in the thermal and salinity regime affect less than 1% of the MRU.

In accordance with the advice given in Guidance 14 (Walmsley, S.F., Weiss, A., Claussen, U., Connor, D. 2017 Guidance for Assessments Under Article 8 of the Marine Strategy Framework Directive, Integration of assessment results. ABPmer Report No R.2733, produced for the European Commission, DG Environment, February 2017), the D7C2 assessment must be carried out for each habitat type that is affected by changing hydrographic conditions and the D7C2 results are not integrated.

In the absence of a threshold for the "Extent" parameter, the state of the habitat could not be provided. Furthermore, according to Decision 2017/848/EU, the results of the assessment of criterion D7C2 (estimated extent of adverse effects by habitat type in each assessment area) are used for the assessment of criterion D6C5. However, in the absence of an operational indicator at the level of Descriptor 6 - Benthic Habitats, these results could not be taken into account in the assessment of D6C5.

The assessment of D7, based on data on anthropogenic activities, highlighted significant variations in exposure to pressures:1/ The Z200 zone is less subject than the coastal zone (MEC DCE) to exposure to the hydrographic pressures considered.2/ The modification pressures of "turbidity" and "bottom nature" present the largest potential areas of exposure (100% of the Celtic Sea marine sub-region). However, the exposure index remains mostly low, and for 90% of the major benthic habitat types, the area of habitat potentially subject to a medium to high risk of modification is greater than 30% of the total area of habitat, as a result of cumulative exposure to hydrographic pressures. Finally, it is important to specify that the incompleteness and uncertainties associated with the input data, as well as the use of expert opinion and subjective decision rules, imply a significant propagation of uncertainty throughout the treatment carried out. The results should therefore be taken with caution.
