Hydrography (EO 7)

Alteration of hydrographic conditions does not adversely affect coastal and marine ecosystems.

Ecological Objective 7 (EO7) Definition:

Alteration of hydrographic conditions does not adversely affect coastal and marine ecosystems.

Key Messages:

  • The location and extent of the habitats impacted directly by hydrographic alterations (CI 15) reviewed existing information on marine habitats which may be affected or disturbed by changes in hydrographic conditions (currents, waves, suspended sediment loads) due to new developments. [...] 
  • The EO7 CI 15 considers marine habitats which may be affected or disturbed by changes in hydrographic conditions (currents, waves, suspended sediment loads) due to new developments. [...]
  • The national monitoring in Mediterranean countries regarding EO7 has not been initiated yet (except for the Contracting Parties that are EU member states, and their obligation of implementing Descriptor 7 of the Marine Strategy Framework Directive), or it is just being initiated. [...]
  • Assessments that estimate the extent of hydrographic alterations (knowing conditions before and after construction) and its intersection with marine habitats are currently rare in the Mediterranean, except for some local studies of Environmental Impact Assessment (EIA) /Strategic Environmental Assessment (SEA). [...]
