Scientists believe that the motion of Earth's continents through plate tectonics has been largely steady over millions of years. New research, however, suggests this drift can speed up or slow down ...

This discovery shows that ice streams move with what Fichtner calls a "stick-slip" motion rather than always flowing smoothly like viscous honey. Glacier ice flows by means of many different ...

Glacier motion in the Amundsen Sea sector of the West-Antarctic ice sheet has been a research topic at the German Remote Sensing Data Center (DFD) for several years. Since 1991 DFD acquires ERS SAR ...

Another decisive advantage of using long wavelength radar signals is the greatly improved temporal coherence, important for the measurement of surface deformation and glacial motion. Thus Tandem-L ...
