Metadata: 2022–2023, APEM Limited, UK Celtic Sea Survey Area, Baseline Digital Aerial Surveys
Abstract:
Celtic Sea Power Limited commissioned APEM Limited to undertake a programme of four seasonal Digital Aerial Surveys across the UK Celtic Sea Survey Area, commencing in August 2022. The surveys were designed to provide baseline information on the distribution and abundance of seabirds and marine mammals, supporting regional density and distribution modelling and understanding of potential overlap with floating offshore wind development in the Celtic Sea. The surveys were undertaken as part of the Cornwall FLOW Accelerator (CFA) project, led by Celtic Sea Power Limited in partnership with the University of Exeter, University of Plymouth, and the Offshore Renewable Energy Catapult (OREC). The CFA project was funded by the European Regional Development Fund (ERDF). Surveys used a transect-based high-resolution digital aerial survey method, with observations georeferenced and internally quality assured.

| Title | The title is used to provide a brief and precise description of the dataset such as 'Date', 'Originating organisation/programme', 'Location' and 'Type of survey'. All acronyms and abbreviations should be reproduced in full. | 2022–2023, APEM Limited, UK Celtic Sea Survey Area, Baseline Digital Aerial Surveys |
| File Identifier | The File Identifier is a code, preferably a GUID, that is globally unique and remains with the same metadata record even if the record is edited or transferred between portals or tools. | 20896ab4-fb50-42c8-9d9b-cafdb7864d21 |
| Resource Identifier | This is the code assigned by the data owner. | TCE-4621 |
| Resource type | The resource type will likely be a dataset but could also be a series (collection of datasets with a common specification) or a service. | series |
| Start date | This describes the date the resource starts. This may only be the year if month and day are not known | 2022-08-27 |
| End date | This describes the date the resource ends. This may only be the year if month and day are not known | 2023-05-24 |
| Frequency of updates | This describes the frequency with which the resource is modified or updated i.e. a monitoring programme that samples once per year has a frequency that is described as 'annually'. | notPlanned |

| Lineage | Lineage includes the background information, history of the sources of data, data quality statements and methods. | The dataset was produced from four seasonal Digital Aerial Surveys undertaken by APEM Limited for Celtic Sea Power Limited between August 2022 and May 2023. Surveys used a transect-based method with APEM’s high-resolution digital camera system mounted in a twin-engine aircraft. Imagery was collected at approximately 1,700 ft altitude and 120 knots, with a ground sample distance of approximately 2 cm and greater than 5% coverage of the sea surface. Images were analysed to identify and enumerate birds and marine mammals to species level where possible. Observations were georeferenced and subjected to APEM internal quality assurance, including checks for missed targets and species identification. The supplied observation data represent raw counts and have not been extrapolated to abundance estimates. |
