Fig. 1

Study area (A) shows the location of Drew Point along the Beaufort Sea Coast in Alaska, USA using ESRI basemap imagery; (B) a field image of the Drew Point Coastline from August 2021 showing collapsed blocks of ice-rich permafrost; (C) a field image of fallen blocks in various stages of dissolution; (D) material eroded by thermal denudation covering the bluff face and (E) the section of the Drew Point coastline under study. The orange line is the coastline from 14 April 2018 depicting the 9 km coastline for annual erosion measurements studied in Jones et al.21. The purple line represents the 1.5 km coastline under study for the sub-seasonal erosion dynamics presented here. ESRI basemap image from June and September 2023. Esri basemap imagery for (A) and (E) were accessed using ArcGIS Pro v. 2.7 (©ESRI); world imagery basemap sources: Esri, DigitalGlobe, GeoEye, i-cubed, USDA FSA, USGS, AEX, Getmapping, Aerogrid, IGN, IGP, swisstopo, and the GIS User Community. Photo in (B) was taken by M. Ward Jones. Photos in (C) and (D) were taken by B. Jones.
