State-decoded locations recorded by six belugas between July 2018 and June 2019. The long-distance movement phase analysed includes all locations not bounded by the summer or winter residency area polygons. ‘Uncertain*’ locations (probability of < 0.9 of being in either the ARS or Transit state), when present, shown in zoomed inset panels only. Zoomed inset panels a-d show examples of state-decoded beluga tracks, with the corresponding dive profiles colour-coded by state shown in the lower panels. (a) beluga LC2018#3, 1st -2nd Sep 2018, (b) beluga LC2018#3, 13th -14th Sep 2018, (c) beluga LC2018#1, 6th Sep 2018 (d) beluga LC2018#8, 6th Sep 2018. Black bars above dive profiles denote periods with missing depth data. All times are given in UTC. Zoomed inset panels only show the track of the individual beluga referred to for that period. Seafloor depth is denoted by brown shading when within the range of depths shown on the y-axis
