Harbour Porpoises in the Southern North Sea - Analysis of Potential Influences of Alpha Ventus in the Context of General Distribution Trends

Abstract

Research Questions:

  • Seasonal and spatial distribution of harbour porpoises?
  • Behavioural reaction related to pile-driving?
  • How far are porpoises displaced? For how long? Return to pre-disturbance levels?
  • Effects of the operation period?
  • Possible to evaluate effects incorporating external anthropogenic pressures and environmental factors?
