Supporting data for: Rapid ice-marginal lake growth in Alaska driven by glacier retreat through bed overdeepenings

In this study, we mapped ice-marginal glacial lakes in Alaska in 2018 and
2024 using Sentinel-2 optical imagery. We mapped glacier-bed
overdeepenings using existing datasets and evaluated how much lake growth
has occurred within these mapped overdeepenings as well as how much
additional growth is possible. Here we provide seven supporting data
products: i) a raster of mapped glacier-bed overdeepenings using best
estimate of ice thickness, ii) a raster of glacier-bed overdeepenings
using ice thickness plus uncertainty, iii) a raster of glacier-bed
overdeepenings using ice thickness minus uncertainty, iv) a 2018
ice-marginal lake shapefile, v) a 2024 ice-marginal lake shapefile, vi) a
2024 ice-marginal lake shapefile joined to glacier-bed overdeepening area,
and vii) RGI 6 glacier inventory joined to glacier-bed overdeepening
area.
