Spatial predictions of stop-over behaviour for narwhal undertaking the nearshore migration route. A Color indicates median predicted move-persistence (γt) as a function of environmental covariates (ice concentration, bathymetry, and slope) throughout October and November. Lighter yellow colors indicate stop-over sites (γt < 0.5). Bounding polygon indicates the 70% kernel density estimate for the extent of all location data used by narwhal migrating nearshore (n = 8). Zoomed-in view of example narwhal tracks that exhibited stop-over behaviour in B Buchan Gulf and Scott Inlet as well as C Home Bay. D For each track, the total period (days) using each stop-over was calculated as the number of 4-h time-steps in each colored ellipse. Broken grey lines indicate individual trajectories of stop-over behaviours during migration
