Extended data - Lituya Bay, Alaska

This is the supplementary data to "Rapid delta growth and tsunami disturbance in Lituya Bay, Alaska" Contents: bay_sedimentation: DOD_1959-1926.tif & DOD_1959-2023.tif: DEMs of difference between the bathymetric surveys of Lituya Bay DOD_1959-1926_0.tif & DOD_1959-2023_0.tif: DEMs of difference between the bathymetric surveys of Lituya Bay based on adjusted rasters that assume a water depth of 0 m for areas that were covered or newly exposed by advance and retreat of Lituya and North Crillon glaciers between two successive surveys. zones_bay.gpkg: Polygons delineating the regions used to estimate the sedimentation in northern Lituya Bay and at the head of Lituya Bay, respectively. zones_deltas.gpkg: Polygons delineating the regions used to estimate the accumulation volumes of Lituya and Crillon deltas. boulder_size: boulder_data.csv: Table containing the boulder locations and axes measurements delta_growth_1985-2025: area_change.gpkg: Areal delta progradation polygons delta_fronts.gpkg: Line features of the mapped delta fronts delta_polygons.gpkg: Delta polygons based on the mapped delta fronts and the 1985 glacier extents area_change.csv: Table summarizing the area change of the deltas in five-year intervals between 1985 and 2025 progradation rates: Input files used to estimate delta progradation including the R-code, the transects along which we measure progradation, the mapped delta fronts, and R-data files of the output glacier_elevation_change: DOD1 & DOD2: Folders containing the co-registered DEMs used to estimate the surface elevation changes of the glaciers in Lituya Bay between 2016 and 2019. The original ArcticDEM strips (pre co-registration) were retrieved from Porter, Claire, et al., 2022, “ArcticDEM – Strips, Version 4.1”, https://doi.org/10.7910/DVN/C98DVS, Harvard Dataverse, V1. zones_stats.gpkg: Geopackage containing the polygones used to estimate the glacier elevation changes of lower Lituya and North Crillon glaciers.
