Figure 5 in Harbor seal use of glacier ice and terrestrial haul-outs in the Kenai Fjords, Alaska

Figure 5. Comparison of numbers of mother-pup harbor seal pairs (MP) counted in Aialik Bay and Northwestern Fjord from 2004 to 2013 using multiple survey methods. Area charts indicate maximum annual counts of MP in Aialik Bay and Northwestern Fjord (light blue) and in Aialik Bay (darker blue). Maximum annual MP counts in Northwestern Fjord are indicated by the blue green line. White dots with 95% CI error bars show generalized linear model (GLM) mean estimate MP based on remote video observations in Aialik Bay during standardized favorable haul-out conditions.
