Atlantic bluefin tuna (ABFT; Thunnus thynnus) is a highly migratory species. To investigate the migrations and vertical behaviours of ABFT migrating to Nordic waters, we deployed pop-up satellite archival transmitting tags on 25 ABFT off Norway (Curved Fork Length: 228-292 cm). We obtained 16 full-year migrations, which differed between individuals, and physically recovered 13 tags, which provided 4,699 days of archival depth and temperature data. ABFT occupied waters from the Arctic Circle to as far south as Cabo Verde, Africa, and occupied depths down to 1190 m and temperatures from 0.5 to 27.8 °C. During their annual migrations, ABFT spent, on average, 68 days in Norwegian waters, 65 days in the Newfoundland Basin, 35 days around the Canary Islands and 33 days in the West European Basin. Most ABFT entered the Mediterranean Sea with a mean entry date of May 13th and visited known spawning grounds, staying, on average, 44 days. All ABFT with full-year deployments returned to Norwegian waters. ABFT displayed ... : # PSAT tag data from Atlantic bluefin tuna tagged off Norway from 2020 to 2022 [https://doi.org/10.5061/dryad.547d7wmg5](https://doi.org/10.5061/dryad.547d7wmg5) This repository contains pop-up satellite archival transmitting (PSAT) tag data (i.e., location, temperature and depth) as well as code used to generate figures and tables in "**Atlantic bluefin tuna tagged off Norway show extensive annual migrations, high site-fidelity and dynamic behaviour in the Atlantic & Mediterranean Sea**" published by Ferter, Pagniello et al. (2024) in Proceedings of the Royal Society B. ## Files The following files are included: 1. META.csv, which contains metadata listed in Table 1 associated with each PSAT tag, 2. SSM.csv, which contains daily locations of tagged Atlantic bluefin tuna derived using a Bayesian state space model described in Block et al. (2011), Jonsen et al. (2005), Teo et al. (2004) and Wilson et al. (2015), 3. PSAT.csv, which contains temperature and depth timeseries of recovered PSAT tags, and 4. ...
