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 ...

A fast-moving Antarctic glacier has been observed by satellites to be stealing ... features like crevasses with the Sentinel-1a and -1b satellites and observe their motion over time. The rate of ...

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 ...

As the ice moves down the mountain it does so in a circular motion which further deepens the hollow, leaving a lip at the end. When the ice melts this hollow can fill with water. These are now ...

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 ...

The brown — and Green Jack-in-the pulpits are up now and the partridgeberries have their pretty red fruit on show. Also present are the eponymous star-flowers. As soon as the forest-canopy completely ...

Ocean water is pushing miles beneath Antarctica’s “Doomsday Glacier,” making it more vulnerable to melting than previously thought, according to new research which used radar data from space ...
