The impact of the physical environment on the foraging energetics of shearwaters and the consequences for breeding success (SHEAR) project from 2022 to 2025 to study manx shearwater (Puffinus puffinus) breeding on two colonies (Bardsey Island and the Calf of Man) within the Irish Sea, to understand the impacts of future climate change. The data collected includes manx shearwater tracking data to study foraging movements. TechnoSmart AxyTrek tags were used to record location (latitude/longitude), tri-axial acceleration, and pressure, which has been converted to depth (in metres). Data were generated by converting files downloaded from the loggers using the tag manufacturer's software. Prey field data were also collectedusing an echosounder. The data collected from this project were funded by the NERC Discovery Science grant NE/W001217/1, awarded to principal investigator Dr Line Cordes at Bangor University.
