Box plots represent the interquartile range of values for adults ( n = 9) and calves ( n = 7) in the Chukchi Sea. The red-dashed line indicates the 50% sea ice organic carbon threshold, with values above this level suggesting elevated sea ice organic carbon contributions to the Pacific walrus diet.
