Figure B-2. Predicted average density (AveDens), standard error (SE(Dens)), and lower and upper lognormal 90% confidence limits(Lo90% and Hi90%) based on the final ETP models for: (a) offshore spotted dolphin (Stenella attenuata), (b) eastern spinner dolphin (Stenella longirostris orientalis), (c) whitebelly spinner dolphin (Stenella longirostris longirostris), (d) striped dolphin (Stenella coeruleoalba), (e) rough-toothed dolphin (Steno bredanensis), (f) shortbeaked common dolphin (Delphinus delphis), (g) bottlenose dolphin (Tursiops truncatus), (h) Risso’s dolphin (Grampus griseus), (i) Cuvier’s beaked whale (Ziphius cavirostris), (j) blue whale (Balaenoptera musculus), (k) Bryde’s whale (Balaenoptera edeni), (l) short-finned pilot whale (Globicephala macrorhynchus), (m) dwarf sperm whale (Kogia sima), (n) Mesoplodon beaked whales (including Mesoplodon spp., Mesoplodon densirostris, and Mesoplodon peruvianus), and (o) small beaked whales (Mesoplodon beaked whales plus “unidentified beaked whale”). Grid cells for each of the individual survey years were averaged across all years to calculate average species density; standard errors and upper and lower lognormal 90% confidence limits were calculated from the grid cell averages and variances using standard formulae. Predicted values were then smoothed using inverse distance weighting (see Section 3.5.1 for details). 192
