Ecosystem overviews

Bay of Biscay and the Iberian Coast ecoregion

Pressure: Other pressures

​​​​​​​​​​​​​​​Other relevant pressures in this ecoregion are:

  • Underwater noise, caused by activities such as shipping, tourism and recreation, and renewable energy installations, which may affect marine mammals, fish, and other organisms using sound or pressure senses.
  • Introduction of non-indigenous species happens primarily through shipping and aquaculture and may affect the benthic community and foodwebs.
  • Introduction of contaminating compounds, due primarily to coastal discharges and maritime transport (shipping). This pressure can affect all ecosystem components but may accumulate in the foodweb, having an effect in particular on higher trophic levels (mammals and birds). Some of these compounds may be very stable and remain in the ecosystem for many decades after their introduction.​
