Extended Data Fig. 4: Trends for constituent concentration across the full ArcticGRO dataset.
From: Recent trends in the chemistry of major northern rivers signal widespread Arctic change
Trend analysis is via a seasonal Mann-Kendall analysis; the Thiel-Sen slope (numerical value) and p-value of the trend analysis (shading) are shown. Corresponding trends in constituent flux are provided in Extended Data Fig. 3. Grey bars illustrate groupings from Extended Data Fig. 2. Units (mg L−1 y−1 or µg L−1 y−1) are provided in Supplementary Table 2.
