	            This data set, part of the NASA Making Earth System Data Records for Use in 
	            Research Environments (MEaSUREs) program, provides 17 years of comprehensive 
	            high-resolution mapping of grounding lines in Antarctica, derived using 
	            differential satellite synthetic aperture radar interferometry (DInSAR) data 
	            from the Earth Remote Sensing Satellites 1 and 2 (ERS-1 and ERS-2), 
	            RADARSAT-1, RADARSAT-2, and the Advanced Land Observing System Phased Array 
	            type L-band Synthetic Aperture Radar (ALOS PALSAR) for years 1994 to 2009. 
	            Parameters include latitude, longitude, sensor, and up to four orbits and 
	            respective dates. 

Data are available via FTP in ASCII text (.txt) 
	            format.

Note. These data are considered provisional pending a review by the 
	            MEaSUREs program. Once the data have been reviewed, this statement will be 
	            removed from this documentation.
