From: A novel method for identifying fine-scale bottom-use in a benthic-foraging pinniped
Core bottom-use areas identified by k-means clustering of dead-reckoned foraging paths for adult female Australian sea lions from Seal Bay, showing cluster 1 dives (lower foraging-effort) in light blue and cluster 2 dives (higher foraging-effort) in dark blue for individuals SB1 (a), SB2 (b) and SB3 (c). Aggregations of cluster 2 dives are circled in dark blue. Isobaths represent depth contours at 25, 50, 75 and 125Â m (light to dark grey). K-means cluster plots, highlighting partitioning of bottom-use and principal components, are shown for individuals SB1 (d), SB2 (e) and SB3 (f)
