Description of data files available on CD

Ablation folder
survey_canes_ablation.xls
Excel file with the measured height of each survey wand above snow/ice surface for the field season.
BG35_pinger.xls
Excel file with sonic ranger data for BG35.
BG50_pinger.xls
Excel file with sonic ranger data for BG50.

Chemistry folder
Ion_Chemistry.xls
Excel file with analyses of chloride, sulphate, nitrate, Mg, Ca, Na of samples collected from crevasses and cores.
Oxygen_isotopes.xls
Excel file with dO18 analyses of samples collected from crevasses and cores.

DEM folder
dem_2003.grd
ASCII file with the 2003 DEM grid, generated using Golden Software Surfer v7.0. Header file format is:

id The identification string DSAA that identifies the file as an ASCII grid file.

nx nynx is the integer number of grid lines along the X axis (columns)
ny is the integer number of grid lines along the Y axis (rows)

xlo xhi xlo is the minimum X value of the grid
xhi is the maximum X value of the grid

ylo yhi ylo is the minimum Y value of the grid
yhi is the maximum Y value of the grid

zlo zhi zlo is the minimum Z value of the grid
zhi is the maximum Z value of the grid

grid row 1
grid row 2
grid row 3 -these are the rows of Z values of the grid, organized in row order. Each row has a constant Y coordinate. Grid row 1 corresponds to ylo and the last grid row corresponds to yhi. Within each row, the Z values are arranged from xlo to xhi. Blanked grid nodes are given a Z value of 1.070141E+038. Rows are 39.855 m apart, Columns are 40 m apart.
