Spatial extent of Arctic river deltas
This geospatial layer (shapefile) provides the spatial extent of 211 river deltas in the Arctic and was established by digitizing Arctic deltas based on (very) high resolution images, which are freely available on GoogleEarth. We digitized the deltas at mapping scale of 1:5,000 to 1:15,000 depending...

This geospatial layer (shapefile) provides the spatial extent of 211 river deltas in the Arctic and was established by digitizing Arctic deltas based on (very) high resolution images, which are freely available on GoogleEarth. We digitized the deltas at mapping scale of 1:5,000 to 1:15,000 depending on the available GoogleEarth images. The area of the resulting polygon shapefile was calculated using ArcMap 10.6.1. The centroids of the polygons were calculated and used for the coordinates of the deltas. This simple mapping provided a first-order estimation of the total area covered by Arctic deltas. In our approach, we used a definition of 'Arctic delta' that includes typical prograding deltas but also estuaries and alluvial fans ending in the Arctic Ocean as well as inland deltas. This includes deltas of size >10 km2 and a representative subset of micro deltas (< 10 km2). Even though there are several (~100) micro deltas not covered by this data set (especially in Greenland, the Canadian Archipelago, or Novaya Zemlya), this only negligibly affects the total area of Arctic river deltas, as the 41 mapped micro deltas only contribute 0.2% of the total delta area in the Arctic.
