Abstract:
We present a comprehensive inventory of thermo-erosion gullies (gullies developed in the Arctic and sub-Arctic areas) in Nordenskiöld Land (Svalbard Archipelago). We used the most recent orthophotos (5 x 5 m pixel size) acquired in 2009-2011 from the Web Map Services (WMS) of the Norwegian Polar Institute. The thermo-erosion gullies were identified and digitised on-screen as polygons in the WGS_1984_UTM_Zone_33N coordinate reference system. We identified a number of 908 thermo-erosion gullies, that will be used along with the thaw slumps inventory to provide the first multi-hazard predictive model in the Arctic.

2022-09-30T11:02:02 – NEW Version: Following the review process, the updated data contains the same basic data (e.g. number of polygons); the additions consist of a few additional columns in the attribute table regarding some basic morphometric parameters (e.g. area, perimeter, P/A, P/sqrt(A), Max. Distan, D/A, D/sqrt(A), Shape index). When referring to the updated data, please use the following paper as a reference: https://essd.copernicus.org/preprints/essd-2022-228/#discussion
