Abstract
This report constitutes the fourth seasonal (July to September 2023) report outlining results from digital aerial surveys conducted in September 2023 within the South-West Celtic Sea under the POSEIDON project and commissioned by Natural England. Surveys were undertaken using APEM’s high-resolution camera system to capture digital still imagery of birds and marine megafauna within the Survey Area.
The survey was successfully carried out across two days in September, with no technical or safety issues. A total of 993 observations were recorded in September 2023, of which 646 were observations of birds and 347 observations of marine megafauna.
