ICESat’s new perspective on ice shelf rifts: the vertical dimension. Geophys
[1] The small footprint ($70 m) and $172 m alongtrack spacing of the Geoscience Laser Altimeter System (GLAS) on the Ice, Cloud and land Elevation Satellite (ICESat) provides unprecedented horizontal resolution for a satellite altimeter. This enables ICESat to map many previously unresolved features...

[1] The small footprint ($70 m) and $172 m alongtrack spacing of the Geoscience Laser Altimeter System (GLAS) on the Ice, Cloud and land Elevation Satellite (ICESat) provides unprecedented horizontal resolution for a satellite altimeter.

We present examples of ICESat-derived elevation data showing topography over rifts on the Amery and Ross ice shelves, widths of rifts and as estimates of the thickness of mélange (a collection of ice and snow trapped inside the rifts).
