Mean bathymetric depth ratio (left), mean depth (top right), and bathymetric depth ratio 80th percentile prediction interval width (bottom right) of Chinook salmon from random forest regression model. For bathymetric depth ratio, zero represents the surface and one the seafloor. Predictions are conditional effects of spatial processes, with year day fixed to 211 (i.e., July 30) and dynamic oceanographic variables fixed to estimated values for July 30, 2020. All other temporal and biological variables are fixed at median values or 0.5 for dummy variables
