The aerial surveys are designed to meet the requirements of the Marine Licence1 granted in respect of the wind farm.

For the internal QA, images were assessed in batches with a different staff member responsible for each batch. Each bird image was reviewed and checked by APEM's own dedicated QA manager, ensuring that 100% of birds found in the images were subject to internal QA. The QA manager, an experienced ornithologist, is responsible for maintaining and updating the image library and also provides advice and guidance to the image processing staff. Upon completion of the internal QA, 20% of the birds located in each survey were subject to external QA by an independent organisation. The appointed auditors for seabirds are the British Trust for Ornithology (BTO). The images for external QA were selected at random using a random number generator. The selected images were provided to the BTO along with information on measured body lengths and wingspans of the birds. All identifications were conducted 'blind' by the external analyst. For marine mammals, all images containing such animals were sent for external ID. The appointed auditors for marine mammals are the Sea Mammal Research Unit (SMRU Ltd). Upon return of the SMRU identifications, the data was updated accordingly with any improvements on the level of identification already achieved by the image analysts and ornithologists at APEM.
