Rapid increase of benthic structural and functional diversity at the , offshore test site wind turbine constructions into the marine environment was the aggregation and production of marine biota on the submersed structures, resulting in a substantial increase of the structural and functional biodiversity of the benthic system.

Underwater construction and operational noise at ,SCI. During the installation of a tripod, a prototype noise mitigation (Small Bubble Curtain) system was tested and evaluated. Measurements of operational noise were made in May and June 2011. This was the first operating noise measurement on wind turbines in the 5 MW class; until then, only smaller turbines had been evaluated.

Marine mammals and windfarms: Effects of , on harbour porpoiseslteration to the habitat where foundations were erected. Visual surveys and stationary acoustic monitoring showed a strong avoidance reaction during pile-driving while during the operational period results were inconclusive. In future, these impacts must be seen in a larger framework to predict the biological significance of cumulative effects.
