Figure 4

Temporal SGI patterns of S. groenlandicus over the 3 collection periods (1899, 1926/1927, and 1968), and combined on a single time scale. The dashed line in each plot represents an SGI of 1.0, with values above this line indicating better than expected years of growth, and values below the line reflecting less than expected growth for those years. Error bars (±1SD) are shown when the sample size exceeded 1 individual; error bars are excluded on the combined plot to enhance readability of patterns.
