  • This red-green-blue (RGB) orthomosaic is composite created from 8994 photographs collected withunmanned aerial vehicles (UAVs) over the eastern part of Qikiqtaruk, Herschel Island, in the Canadian Yukon (69.5N, 138.8W). The images were collected on the 10th and 11th of August 2017. Further details on the image processing are provided in the Lineage section. This dataset was created by Andrew Cunliffe, with support from Isla Myers-Smith, William Palmer, Jeffrey Kerby and other members of Team Shrub (, in order to inform ongoing ecological monitoring studies in this area. Part of this orthomosaic was used for a study into permafrost coastline retreat, published in The Cryosphere (Cunliffe, A. M., Tanski, G., Radosavljevic, B., Palmer, W. F., Sachs, T., Lantuit, H., Kerby, J. T., and Myers-Smith, I. H.: Rapid retreat of permafrost coastline observed with aerial drone photogrammetry, The Cryosphere, 13, 1513-1528,, 2019).

  • This is a survey over the changing topography of a massive ice type site, Peninsula Point (UTM 8N 573400, 7701000), within the Canadian National Landmark, NWT, Canada. These data can be used as a reference for future such studies to assess massive ground ice presence. This dataset contains the survey data from Tromino 3G ENGY instruments, collected from 2019-07-31 - 2019-08-03. The project files contain the metadata of each instrument position in UTM and acquisition times. Data were collected by Northumbria University and Natural Resources Canada. Funding was provided by NERC Arctic Office.
