The parameter weights for depth were very high across all categories during spring (females, 1; males, 0.9; juveniles, 0.9; Table 4), and for the autumn/winter the scores were slightly lower for males and females (0.86 for both; juveniles: 0.99; Table 5). The predictive graphs (Figure 4) show that this is an important variable for all three groups when it comes to annual habitat selection. In spring, juveniles prefer depths of 0–600 m, males >600 m, and females the range of 200–1200 m. In autumn/winter, juveniles use areas with depths from 750 m while females used areas with depths from 600 m and deeper.SST
