Summary of distance sampling analyses.

Results of distance sampling analyses of a polar bear aerial survey conducted in northern Foxe Basin, Nunavut, Canada during August – September, 2012. Highly supported models (ΔAICc<3) are presented. In the column Model, the key function is followed by adjustment terms or covariates (VIS =  visibility; poor/fair (e.g., glare, light fog or rain) or excellent; LIGHT =  light conditions; overcast, mostly cloudy, or partly cloudy/clear). ESW =  Effective strip width (meters). p =  Detection probability.  =  Abundance estimate. Goodness of Fit metrics: C-S =  Chi-squared; K-S =  Kolmogorov-Smirnov; C-vM =  Cramér-von Mises.
