	            This data set provides a modeled radar attenuation rate profile, showing the 
	            predicted contributions from pure ice and impurities to radar attenuation at 
	            the Vostok 5G ice core site in Antarctica, as well as the total attenuation 
	            rate and its formal uncertainty. The model data are based on borehole 
	            temperature logs, concentrations of major soluble ions measured from melted 
	            ice core samples, and information about the electrical conductivity of ice. 
	            Attenuation rates and their spatial variability are important constraints for 
	            radar studies of ice sheets. Parameters include depth, total attenuation rate, 
	            and attenuation rate contribution from pure ice, acidity, and salinity.

Data 
	            are available via FTP as a text file (.txt) with columns in comma separated 
	            value format.
