Supporting Data - Shallow Fracture Buffers High Elevation Runoff in Northwest Greenland

This dataset contains supporting data accompanying Culberg, Chu, & Schroeder, "Shallow Fracture Buffers High Elevation Runoff in Northwest Greenland", Geophysical Research Letters, 2022. 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 the Supporting Information Figure S6.
