Original provider:\nInstitute of Marine Research\n\nDataset credits:\nInstitute of Marine Research\n\nAbstract:\nThis dataset contains high-resolution (0.2 Hz) biologging data collected with pop-up satellite archival tags (Wildlife Computers, miniPAT-348) externally deployed on four basking sharks (Cetorhinus maximus) in the Northeast Atlantic for a full year between 2022 and 2024. The data underpin the study: "Wide-ranging, year-round breaching behaviour of basking sharks revealed by long-term biologging". The data include georeferenced occurrence records and associated environmental and behavioural measurements (e.g., water temperature, depth, light intensity, triaxial acceleration). These data support analyses of seasonal and spatial patterns in breaching behaviour.\n

Physically recovered tags recorded water depth, temperature, light level, and triaxial acceleration at 0.2 Hz.\n\nLocation estimates were derived from a gridded hidden Markov model implemented in the R package HMMoce. This uses convoluted spatial likelihoods based on light level, bathymetry, sea surface temperature and ocean heat content with a diffusive movement kernel to generate daily posterior location probabilities and most probable tracks via the Viterbi algorithm. Position uncertainty was quantified using the x and y dimensions of the daily 95% Utilization Distribution contour as a bounding box.
