Results from the generalized additive model (GAM) showing partial effects of spatial, temporal, and environmental variables on MHIA bias: (a) depth, (b) distance offshore, (c) day of year, and (d) year. Solid lines represent the smoothed model fits and grey shaded regions show the 95% confidence intervals. In (d), 2011 was used as a baseline to which all other years are compared.
