Fig. 4

Monthly a depth and b temperature distributions of tagged female steelhead kelts from Prince of Wales Island in southern southeast Alaska. Sample sizes for each month are denoted immediately above the x-axis of panel b. Note that panel a only portrays depths < 30 m, as this window contained 99% of all recorded depths. For boxplots, median depths/temperatures are solid lines, and boxes represent the first and third quartiles. Whiskers represent the largest observation less than or equal to the box, plus or minus 1.5 times the interquartile range, and black dots represent outliers
