For the first time on a continent-wide scale, scientists have applied new airborne remote-sensing techniques that push beyond long-standing limits to geophysical, geodetic, and glaciological studies. In the process, they have delineated several major crustal boundaries beneath the Greenland ice cap and possibly traced the path of the Iceland hot-spot across central Greenland (see Figure 1). They have also greatly improved the geoid, or gravity reference surface of the Earth, for the region; provided ground truth for satellite altimeter studies; and established a baseline for determining the growth or shrinkage of one of the world's major ice sheets. The data will aid understanding in areas ranging from the geologic structure of Greenland to global climate change.
