Abstract
This report constitutes the first seasonal (October to December 2022) report outlining results from digital aerial surveys conducted in January 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 in in a single day in January 2023, with no technical or safety issues. Due to weather delays, it was not possible to carry out the survey by the end of December 2022. A total of 746 observations were recorded in January 2023, of which 658 were observations of birds and 88 observations of marine megafauna. APEM will continue to monitor the site for these species and others during the remaining seasonal surveys.
