Habitat suitability predicted from the gradient boosted model and spatial accuracy maps for whales displaying foraging behaviour in the North West of Western Australia (April to September). Shown are a continuous (0–1) relative habitat suitability, b thresholded suitable habitat (pink) and validated suitable habitat (red; suitable habitat restricted to areas with spatial AUC and spatial Kappa > 0.4) overlaid with geomorphologic features [32], c spatial distribution of model accuracy (spatial Kappa) and d spatial distribution of model accuracy (spatial AUC). Black dotted contours represent the 200 m bathymetry (shelf break), and canyons are outlined in light grey
