Foraging locations and elongation distributions for 401Y and 397G. a and c Post-filter GPS positions (N = 574) for leopard seal 401Y. Black circles indicate areas associated with benthic foraging for fish as identified by video and dive data. a A map of all movement tracks with points color coded by foraging trip. c An elongation distribution map which plots the isopleths sorted by descending elongation (‘ecc’). Hulls were created using the fixed ‘a’ method (a = 2000, s = 0.06). b and d Post-filter GPS positions (N = 768) for leopard seal 397G. Black triangles indicate areas associated with Antarctic fur seal pup processing as identified by video data. b A map of all movement tracks with points color coded by foraging trip. d An elongation distribution map which plots the isopleths sorted by descending elongation (‘ecc’). Hulls were created using the fixed ‘a’ method (a = 2250, s = 0.04).
