ASE05 ICE THICKNESS MODEL version 1.0 
  Wed Apr 12 21:27:41 CDT 2006 

ASE05.lonlatthkbed is a table of latitude, longitude, all ice thickness and bed 
elevations + bathymetry with 5 km grid spacing. 

The binary grids ASE05icethk.bin and ASE05bedelv.bin are projected in Polar 
Stereographic with the latitude of true scale 71 degrees south. The limits (in 
meters) are -1800000/-900000/-900000/100000 and the cell size is 5000, using 
pixel registration. The grid values are 2-byte little endian integers arranged 
by row.

The reference datum is WGS-84, and the bed elevations are created by subtracting 
the ASE05 grounded ice thickness model from J. Bamber's unpublished GLAS-ERS-1 
Antarctic DEM, and marine bathymetry data from the WGS-84 sealevel.

Glacier catchment and Holt et al. (2006) if discussing areas within the 
Thwaites Glacier, Smith Glacier catchments
