Figure 4 in Quantitative assessment of species identification in aerial transect surveys for ice-associated seals

Figure 4. Observed species, age class, and confidence level probabilities for four species of ice-associated seals in the Bering Sea. True species and age classes include spotted seal pup (SDP), spotted seal nonpup (SDN), ribbon seal pup (RNP), ribbon seal nonpup (RNN), bearded seal pup (BDP), bearded seal nonpup (BDN), ringed seal pup (RDP), and ringed seal nonpup (RDN). Observed species classifications include spotted seal (red), ribbon seal (green), bearded seal (yellow), ringed seal (blue), and unknown seal (white). Observed age classes include pup, nonpup, and unknown. For observed species classifications, darker shades indicate greater confidence (e.g., light red = spotted seal guess, red = spotted seal likely, and dark red = spotted seal positive). For observed age classes, the relative density of hash lines indicate greater confidence (e.g., low density = guess, medium density = likely, high density = positive). Solid colors with no hashing indicate unknown age classification. Top panel (a) includes results from an analysis with no observer effects on model parameters. Bottom four panels (b) correspond to four different observers from an analysis including observer effects.
