  1. Tagged belugas that transmitted for < 4 days were not included due to early tag failure or uncertainty about tag performance. Other tags not programmed to collect time-series depth data or underway location were also excluded. Displacement distance and proportion of time in surface 2.5 m only calculated for belugas that occupied the spatial polygon for ≥ 3 days. Calculations from the spatial polygon are from June 29 (earliest deployment date) to July 31
