Abstract
This report constitutes the second seasonal (January to March 2023) report outlining results from digital aerial surveys conducted in March 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 by two planes in a single day in March 2023, with no technical or safety issues. A total of 818 observations were recorded in March 2023, of which 374 were observations of birds and 444 observations of marine megafauna. APEM will continue to monitor the site for these species and others during the remaining seasonal surveys.
