Description overall status |
This assessment has considered the activities, dredging and disposal of dredged spoil, which have caused permanent changes to the hydrographical conditions during the assessment period. The level of pressure from these activities causing hydrographical changes to the seabed and water column within Irelands MSFD area was very low overall between 2014 and 2018, at 533 km2 or 0.109% of Irelands MSFD area. Ireland has achieved Good Environmental Status for the spatial extent and distribution of permanent hydrographical changes within its maritime area.
The permanent alteration of hydrographical conditions during the period 2014 to 2018 is limited to 0.109 % of the Irish Marine Strategy Framework Directive area. The impact from these alterations was localised with respect to hydrographical conditions and the short-term water quality impacts experienced during the dredging and disposal activities. The adverse impacts on the marine ecosystems are minimal from the very limited hydrographical changes which have occurred.
