Figure 8
Average daily sea ice concentration in core areas of male walruses in Svalbard, Norway. Daily ice concentrations in kernel areas were extracted from a 0.05 × 0.05 decimal degree analysis grid of operational sea ice charts. The colours indicate the season, red for summer and blue for winter. The shaded area behind the lines illustrates the range of ice concentrations encountered each day within core areas (50% UD). Above each season the mean sea ice concentration is given. Animal ID is inserted in the top right corner of each panel.
