The report first describes impacts from offshore windfarms on marine mammals and defines the spatial and temporal scope of investigations in order to detect impacts on marine mammals. Impacts from offshore windfarming occur at very different spatial and temporal scales: Construction work, especially pile driving, may result in short-termed but long ranged impacts, whereas the operation of windfarms is expected to result in local but long-lasting impacts. The report reviews the standard methods used in studies on marine mammals in relation to offshore windfarms. Statistical power of line transect surveys using aircrafts and ships and Static Acoustic Monitoring using T-PODs is analysed from datasets obtained in German studies.

The report should aim to describe a variety of methodologies in detail and indicate the benefits and difficulties of each methodology in order to be able to assess their relative benefit. An estimate of the relative costs of implementing methodologies should also be provided. The objectives of the project are to: Indicate a practical, statistically robust and cost effective methodology (or choice of methodologies) using evidence based reasoning that will provide evidence of the impacts (or lack of impacts) of construction, operation and decommissioning of offshore windfarms on marine mammals. If applicable, identify areas where further research or development of methodologies is required due to a current lack of adequate information.
