Description
Summary:Permafrost landscapes are changing around the Arctic in response to climate warming, with coastal erosion being one of the most prominent and hazardous features. Using drone platforms, satellite images, and historic aerial photographs, we observed the rapid retreat of a permafrost coastline on Qikiqtaruk – Herschel Island, Yukon Territory, in the Canadian Beaufort Sea. This coastline is adjacent to a gravel spit accommodating several culturally significant sites and is the logistical base for the Qikiqtaruk – Herschel Island Territorial Park operations. In this study we sought to (i) assess short-term coastal erosion dynamics over fine temporal resolution, (ii) evaluate short-term shoreline change in the context of long-term observations, and (iii) demonstrate the potential of low-cost lightweight unmanned aerial vehicles (“drones”) to inform coastline studies and management decisions. We resurveyed a 500 m permafrost coastal reach at high temporal frequency (seven surveys over 40 d in 2017). Intra-seasonal ... : This dataset consists of a time-series of twelve co-registered and orthorectified aerial images, which depict the erosion of a permafrost coastline on Qikiqtaruk - Herschel Island in the Canadian Yukon (69.57°N, 138.9°W). They are the core dataset underpinning the analysis published in The Cryosphere. Please refer to the published article for additional information on the origin and production of these geotiffs. All twelve raster files have been clipped to the spatial extent of the study area used in the article. ...
