2022-2023, University of St Andrews and Sea Mammal Research Unit and Scottish Oceans Institute, Marine Characterisation Research Project, Seal Tagging (WP13) series https://portal.medin.org.uk/portal/start.php?tpc=015_9d7b838a-0ee2-4078-a578-ddd03d272b05 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. WP13 will assess the use of the area within and surrounding the Morlais Demonstration Zone (MDZ) by grey seals (Halichoerus grypus). Twenty SMRU Instrumentation GPS Phone Tags were deployed on grey seals in July/August 2023 which collect GPS locations and dive data over a period of months. The tags were successfully deployed over a two-week period on both sexes and across age-classes of seals. Data collected will be analysed to provide an understanding of seal distribution and behaviour within the MDZ, and a quantitative assessment of dive data will be conducted to quantify the relative time spent in the at-risk depths of turbine rotor blades. GPS/GSM (Global Positioning System/Global System for Mobile communication) tags deployed on grey seals in the area surrounding the Morlais Marine Demonstration Zone around the coast of Anglesey to collect data on their distribution, movement, and behaviour. These tags record data on the at-sea locations and dive depths of seals. 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. 20250116T16:12:50 20231112T00:00:00
