Figure A-1 Predicted yearly and averaged densities based on the final CCE models for: (a) striped dolphin (Stenella coeruleoalba), (b) short-beaked common dolphin (Delphinus delphis), (c) Risso’s dolphin (Grampus griseus), (d) Pacific white-sided dolphin (Lagenorhynchus obliquidens), (e) northern right whale dolphin (Lissodelphis borealis), (f) Dall’s porpoise (Phocoenoides dalli), (g) sperm whale (Physeter macrocephalus), (h) fin whale (Balaenoptera physalus), (i) blue whale (Balaenoptera musculus), (j) humpback whale (Megaptera novaeangliae), (k) Baird’s beaked whale (Berardius bairdii), and (l) small beaked whales (Ziphius and Mesoplodon). Predicted values were smoothed using inverse distance weighting (see Section 3.5.1 for details). Black dots show actual sighting locations. 107
