East Anglia ONE Offshore Windfarm Generation Assets Monitoring Plan
September, 2016
33.
Depending on the answers to these high level questions, more specific ones will be considered, such as:
• Over what distance do gannet show avoidance behaviour of the wind farm? • Over what distance do gannets show avoidance of individual turbines (assuming they enter the wind farm)? • What height do gannets fly outside and inside the wind farm? • Over what distance do species of auk avoid turbines? • How does turbine avoidance distance translate into rates of wind farm displacement?
34.
Note that the above list is not intended to be comprehensive but to demonstrate that the monitoring methods being proposed have been designed to enable consideration of these types of questions.
3.1.1.3 Survey area 35.
The proposed survey design (Figure 1) meets the following requirements as specified in Section 4.2 of the Aerial Survey Power Analysis report which was reviewed and discussed and agreed in principle with Natural England during a meeting on 15th April 2016 (Appendix A):
• Eight surveys, 2 each in October and November, 1 each in December to March; • Primary transects (n=14) will be orientated approximately east-west with a bearing of c. 81° (Figure 1), while additional transects (n=4) will cross the wind farm approximately north-south at a bearing of c. 4.5°, aligned with turbine locations;
• Transect width will be 463m; and, • East-west transects will be spaced at 2.7km and north-south transects at 2km, giving an overall coverage of approximately 22%.
