2023-2024, Ocean Science Consulting, Marine Characterisation Research Project, Surface (WP3) and Underwater (WP4) Imaging series https://portal.medin.org.uk/portal/start.php?tpc=015_872210fd-0e3b-4c78-8074-eb03780783b5 This data series was collected for the Marine Characterisation project (MCRP) which forms part of the Morlais tidal energy project, managed by Menter Môn and funded by the European Regional Development Fund and The Crown Estate. This series consists of data collected from a camera system, consisting of a subsea RGB camera and associated computers and power supply, developed and deployed on a buoy at the Morlais Demonstration Zone (MDZ). This subsea camera collected data and ran a custom Machine Learning (ML) detection algorithm in real-time. Data were successfully recorded over a four month and 16-day period during four deployments. These data have been collected to investigate the feasibility of surface (data from 2023, Ocean Science Consulting ltd, Marine Characterisation Research Project, Surface Imaging (WP3)') and underwater cameras to detect marine fauna, with the aim of providing an automatic detection and classification system for marine animals to enable the automatic triggering of deterrents on a tidal turbine energy site in Wales. This series also contains the surface imagery collected through shore-based surveys to record diving seabird presence and behaviour within demonstration zone of tidal turbine site in Wales, up to 5 km from land. Nest surveys also conducted to calculate trip duration of adults from nests during breeding season. Access to the MCRP data is strictly subject to the MCRP Data Terms of Use. Please ensure that you read and understand the Terms of Use prior to using any of the data as you will be bound to comply with the same. The MCRP Terms of Use are the prevailing Terms of Use and supersede that of Marine Data Exchange Terms of Use in relation to MCRP data. 20250116T16:13:30
