Figure S1 from Dive behaviour and foraging effort of female Cape fur seals Arctocephalus pusillus pusillus

Radial graph summarizing the frequency of departure and arrival times for a single foraging trip of 32 lactating Cape fur seal females fitted with depth recorders at the Kleinsee seal colony, South Africa, during the austral winters of 2006-08. The vertical axis labels represent the number of animals, the radial axis labels represent hours of the day in 2 hour bins (SAST), and the dark shading on the outer radial line represents the hours between dusk and dawn (mean civil twilight times coinciding with the dates of the study for the nearby town of Port Nolloth, South Africa).
