Extended Data Fig. 3: Boxplots of annual Grand Combin 2018 (GC18) and 2020 (GC20) δ18O and major ion concentrations.
From: High-altitude glacier archives lost due to climate change-related melting
Comparison of the annual box plots showing the minimum, first quartile, mean (square), median, third quartile, and maximum of a) δ18O and the concentrations of b) NH4+, c) NO3−, and d) SO42−. Number of samples per year: GC18: n = 16, 12, 12, 20, 18, 23, 10, 9 (2011–2018); GC20: n = 15, 16, 21, 16, 13, 19, 27, 15, 27, 17, 25, 27, 19 (2008–2020).
