Monitoring of ice velocity field is one of the key issues to glacier dynamics understanding. Surface velocity fields can provide useful information on phenomena such as glacier surges or ice fall. They can also reflect the effect of global warming on the dynamic of ice masses. Although the surface displacements of glaciers can be monitored locally with ground GPS points, this solution is diffic...
Accurately mapping and monitoring glacier changes over decades is important for providing information to support sustainable use of water resource in arid regions of northwest China. Since 1970, glaciers in the Eastern Altun Mountains showed remarkable recession. Further study is indispensable to indicate the extent and amplitude of glacial change at basin and individual glacier scale. In this ...
Alaskan glaciers are among the largest regional contributors to sea-level rise in the latter half of the 20th century. Earlier studies have documented extensive and accelerated ice wastage in most regions of Alaska. Here we study five decades of mass loss on high-elevation, land-terminating glaciers of the Wrangell Mountains ( 4900 km) in central Alaska based on airborne center-line laser altim...
