Digital aerial surveys are our preferred surveying method, as technological advancements provide more accurate counts and are more cost-effective than traditional boat surveys. Aerial surveys are also less intrusive: as seabirds associate boats with fishing discards, they are more likely to surround a survey boat.
With ten years’ experience in offshore wind in the US, we are well versed to manage the whole surveying process from survey design through the survey flight(s) to data analysis. Using our own equipment, technology and techniques we have developed in house, we provide our clients with a permanent record that can be recalled and referred to at any point in the future.
An APEM Inc task specialist is on board every survey flight to constantly review the data captured, and make immediate adjustments if required to mitigate the risk of needing to fly another survey.
Able to fly day or night, we collect imagery at a range of resolutions starting at 1cm GSD (Ground Sampling Distance). Our custom-made specialist sensors and cameras, including LiDAR give us the highest confidence in our results. We provide our clients with accurate and precise flight heights, directions of movement, behavior and – where possible – age and sex of the birds.
We believe in producing reliable data that can be used for a multitude of purposes. As well as population modeling and collision risk modeling, our technical consultancy support includes advice and guidance on meeting legislative requirements in the marine environment and impact assessment to support permits relating to the federal National Environmental Policy Act (NEPA) and /or Endangered Species Act (ESA).
