Varner and E. Lim, CIRES, University of Colorado at Boulder. The image was created from ETOPO1 Ice Surface (cell-registered). The image was created with Generic Mapping Tools (GMT) [http://gmt.soest.hawaii.edu/] using three color palettes: blues for ocean depths and above sea-level lakes; greens and browns for dry land areas; and shades of white for the Antarctic and Greenland ice sheets and glaciers greater than 100 km2 using the GLIMS Glacier Database [http://nsidc.org/glims/] at the National Snow and Ice Data Center [http://nsidc.org/index.html]. More info on the development of ETOPO1 dataset can be found at http://www.ngdc.noaa.gov/mgg/global/relief/. The image was clipped at 35 degrees north and reprojected to a North Pole Lambert Azimuthal Equal Area projection by the Arctic Research Mapping Application (ARMAP) team [http://armap.org]. The web mapping service is hosted by the Systems Ecology Laboratory (SEL) [http://sel.utep.edu] at the University of Texas at El Paso.", "summary": "Topography, Bathymetry", "title": "Arctic_Base_Map", "tags": [ "Arctic", "Bathymetry", "Elevation", "imageryBaseMapsEarthCover", "Oceans", "Topography" ], "type": "Map Service", "typeKeywords": [ "ArcGIS", "ArcGIS Server", "Data", "Map Service", "Service" ], "thumbnail": "thumbnail/thumbnail.png", "url": "", "extent": [ [ -180, 8.28504111505345 ], [ 180, 90 ] ], "minScale": 0, "maxScale": 1.7976931348623157E308, "spatialReference": "WGS_1984_North_Pole_LAEA_Alaska", "accessInformation": "Amante, C. and B.
