Fig. 2: Multi-decadal changes on Kennicott and Root Glaciers.
From: An 85-year record of glacier change and refined projections for Kennicott and Root Glaciers, Alaska
a–e Spatially-distributed elevation change rates from 1938–2023 overlaying the IFSAR DEM hillshade. Discs show the mean annual elevation change for the Kennicott Glacier terminus, Kennicott Glacier ablation area (labeled as “Kennicott Glacier”), and Root Glacier ablation area (labeled as “Root Glacier”). The value in the center of each disc represents the mean annual elevation change of the total measured area (Kennicott and Root Glaciers). f, g Annual mass changes (f) of the three areas (g) are shown in multi-decadal periods aligning with (a–e). The Hugonnet et al. (2021)1 mass change is shown for both the area covered by the historical DEMs and glacier-wide. The area covered by historical DEMs post-1957 represents over 95% of glacier-wide mass loss (Supplementary Note 1). Large uncertainties exist in glacier-wide mass change from Hugonnet et al. (2021)1.
