Description

This dataset contains supporting data accompanying Culberg, et al "Shallow Fracture Buffers High Elevation Runoff in Northwest Greenland" submitted to Geophysical Research Letters. It includes the following:

  • Ice-penetrating radar-derived mappings of transient firn aquifers and buried refrozen ice complexes (ice blobs) beneath ice slabs in Northwest Greenland.
  • Porosity estimates derived from the inversion of ice-penetrating radar reflectivity for the 20150510_01 Ultrawideband MCoRDS transect flow in Northwest Greenland as part of NASA OIB.
  • An NDWI stack image showing the maximum NDWI on a per pixel basis from all Landsat images between 2000 and 2016 for the region.
  • Data for a time series of NDWI within the upslope catchment of each aquifer or blob.
  • Locations of moulins, supraglacial lakes, and drained supraglacial lakes from high resolution optical imagery.
  • Linear features extracted from the high resolution optical imagery.
  • Surface crevasse densities and surface water feature densities inferred from the extracted linear features for the northern and southern portions of the ice slab region.
  • Resistive stress and fracture toughness data for each location where fractures are inferred from the high resolution optical imagery.
  • Full resolution image files for WorldView imagery used in Supporting Figure S6.
