Glacier - Ice Flow, Melting, Surges: Most glaciers follow a regular and nonspectacular pattern of advance and retreat in response to a varying climate. A very different behaviour pattern has been reported for glaciers in certain, but not all, areas. Such
“The technology will, on the one hand, deflect the heat from direct sunlight away from the glacier. At the same time, the glacier’s own energy can be radiated outward through the porous material to keep temperatures low and slow down the melting rate,” Professor Zhu explained. Scientists ...
A series of huge channels - some almost a kilometre below the ice - allow the warmer, deep ocean water to flow up to the front of the glacier, melting it increasingly rapidly. 科学家们认为冰川加速消融的原因是:海底有巨大的通道,其中一些通道在冰下约一千米,这些巨大的通道让暖流涌向冰川前端,使...
our rate-and-state framework introduces a stability criterion for the onset of propagation that may explain why certain glaciers have speed up events that do not evolve to glacier-wide surges12, and it is capable of explaining the relationship between sliding speed, propagation speed and ice thick...
1, which can be projected to glacier ice 8,000–10,000 ft thick. This curve shows the fusion behaviour of various confined ice and unconfined water systems as derived from our experimental time–pressure–temperature researches. Briefly, the data show that the melting point of the ice is a ...
The melting of glaciers is well documented, but when looking at the rate at which they have been retreating, a team of international researchers steps back and says not so fast.

The ice is melting at an unprecedented rate, revealing a wreckage hidden long ago. 冰层正在以前所未有的速度融化,暴露出很久以前隐藏的残骸。 On alleged glacier this aircraft lost in the 1960s has re-emerged. 在这片冰川上,这架在二十世纪六十年代失踪的飞机重新出现。
Calculations based on the rate of melting 15 years ago had suggested the glacier would last for 600 years. But the new data points to a lifespan for the vast ice stream of only another 100 years. The rate of loss is fastest in the centre of the glacier and the concern is that if th...
