Marine mammals

During the construction of offshore wind farms, bridges, pipelines or cable routes, humans interfere with the habitat of marine mammals such as harbor porpoise, harbor seals and grey seals in the North- and Baltic Sea. For example, uring foundation pile driving of wind turbines the created hydro-sound can disturb or damage the auditory organs of marine mammals. These interferences may have an impact on the behavior and distribution of marine mammels found in the area.
