Group: Summary

   The Hydrologic Sub-basins of Greenland data set contains Geographic 
   Information System (GIS) polygon shapefiles that include 293 hydrologic 
   sub-basins of the Greenland Ice Sheet, as created by Lewis and Smith (2009). 
   Five km Digital Elevation Models (DEMs) of ice-surface and bedrock topography 
   (Bamber et al. 2001) were used to estimate the hydraulic potentiometric 
   surface for Greenland, which accounts for the effects of ice overburden 
   pressure, such as hydrostatic pressure, surface topography, and underlying 
   bedrock topography (Paterson 1994). Using the 5 km potentiometric grid, a 
   modeled basin network for Greenland's ice sheet was created using the 
   hydrological tools within ESRI ArcGIS (ArcInfo 9.2). Although the GIS 
   initially generated more than 293 basins, basins less than 100 km2 in size, as 
   well as basins located completely outside of the ice sheet extent, were 
   removed from the data set. Data are available via FTP, and can be read in any 
   GIS software. The following journal article provides documentation for this 
   data set: Lewis, Sarah and Laurence Smith. 2009. Hydrologic Drainage of the 
   Greenland Ice Sheet. Hydrological Processes DOI: 10.1002/hyp.7343. This 
   journal article can be accessed from the Documentation link at the top of this 
   Web page.
