    "description": "This report constitutes the first seasonal (October to December 2023) report outlining results from digital aerial surveys conducted in December 2023 within the Central North Sea under the POSEIDON project and commissioned by Natural England. Surveys were undertaken using APEM\u00e2??s high-resolution camera system to capture digital still imagery of birds and marine megafauna within the Survey Area. \r\n The survey was successfully carried out across two days in December 2023 with no safety issues. A total of 2,813 observations were recorded during the survey in December 2023, of which 2,715 were observations of birds and 98 were observations of marine megafauna. APEM will continue to monitor the site for these species and others during the remaining seasonal surveys.",
