Sharp, Department of Earth & Atmospheric Sciences, 1-26 Earth Sciences Building, University of Alberta, Edmonton, AB, Canada, T5K 1J8} [Geophysical Research Letters, doi:10.1029/2009GL042030, 2010.] Introduction Filename 2009Gl042030.txt auxiliary online material includes an ASCII text data table containing Yukon glacier inventory data. The section below (header 2009GL042030.txt) describes the full contents of this auxiliary material. These data were derived from digitization of orthorectified archive air photos and Landsat 7 satellite imagery of the entire glaciated area of the Yukon, NW Canada (see manuscript for full details of methods and processing). All data are contained within the table described by this single text file (2009GL042030.txt). 2009GL042030.txt These data are in tab delimited ASCII text format, organised in rows and columns with the following column headers: - Basin_ID Integer value for individual basin identification - UTM_east Universal transverse mercator easting coordinate of glacier - UTM_north Universal transverse mercator northing coordinate of glacier - Zone WGS84 UTM zone number - Glacier_name If known - (Surge) Type Identification of 'normal' or 'surge-type' - Evidence Evidence for identification of surge-type glaciers - 58/60_area *10^6 m^2 1958/1960 areal extent (units: *10^6 m^2) - 58/60_area m^2 1958/60 areal extent (units m^2) - RS data source Source of 1958/1960 extents - Name_and_institution Name of operator and institution where work was completed - Description_of_processing Description of operator processing - 06/08_area *10^6 m^2 2006/2008 areal extent (units: *10^6 m^2) - 06/08_area m^2 2006/2008 areal extent (units m^2) - RS data source Source of 2006/2008 extents - Name_and_institution Name of operator and institution where work was completed - Description_of_processing Description of operator processing - 58/60_vol m^3 Arendt 1958/1960 scaled volume (units m^3) using Arendt scaling coefficients (C0/C1 = 0.280/1.375) All calculations were performed by scaling area in units m^2 to volume in units m^3. - 06/08_vol m^3 Arendt 2006/2008 scaled volume (units m^3) using Arendt scaling coefficients (C0/C1 = 0.280/1.375) - 58/60_vol km^3 Arendt 1958/1960 scaled volume (units km^3) using Arendt scaling coefficients (C0/C1 = 0.280/1.375) - 06/08_vol km^3 Arendt 2006/2008 scaled volume (units km^3) using Arendt scaling coefficients (C0/C1 = 0.280/1.375) - 58/60_mass km^3 w.e.
