These two ice sheets encompass more than 95 percent of the earth's glacial ice. The Greenland ice sheet is almost 10, 000 feet thick in some areas, and the weight of this glacier is so heavy that much of the region has been depressed below sea level. Smaller glaciers that occur at ...
Three quarters of the Earth's fresh water supply is still tied up in glacial ice, a reservoir of untapped fresh water so immense that it could sustain all the rivers of the world for 1,000 years. Floating on the oceans every year are 7,659 trillion metric tons of ice encased in 10000...
The causes of atmospheric methane (CH) changes are still a major contention, in particular with regards to the relative contributions of glacial-interglacial cycles, monsoons in both hemispheres and the late Holocene human intervention. Here, we explore the CH signals in the Antarctic EPICA Dome C...

摘要: Presents a groundwater data from the Glatt Valley, Switzerland, which was ice-covered after a glacial advance during the last glacial maximum. Impact of glaciation on groundwater recharge and dynamics; How local groundwater recharge can be prevented....
In particularly wet years, short stretches of an otherwise dry stream-bed may have flowing water because the water table rises to intersect the land surface. [Glossary] Sediment: materials (such as sand or small rocks) that are deposited by water, wind, or glacial ice. Topography: the shape...

Broad streaks of ice, ～1 km thick, called "ice streams", having horizontal width of several 10s of km, slide over their bed (of soil-like matter, which was seafloor in the last inter-glacial period) at > 100 m/yr, whereas they are bordered laterally by stagnant ridges flowing at <...

We investigated the response of lake algal communities to changes in glacial meltwater from the Renland Ice Cap (Greenland) through the Holocene to assess whether influxes always elicit consistent responses or novel responses. We measured sedimentary algal pigments in two proximal lakes, snow-fed ...
