Sentences with phrase «through subglacial»

Runoff from steep ice - cliffs, or through subglacial flow driven by water percolating through pores or fractures, will convert a high fraction of melting into ablation.

It can also flow through subglacial channels.

But, as the thickness of the ice over the volcano (between 100 and 400 meters) and the volume of lava are both unknown, it's also unclear whether an eruption will break through the ice, or whether it will remain subglacial.

In 2012, the Russian Antarctic Expedition completed drilling through nearly 4 kilometers of ice to reach the surface of subglacial Lake Vostok.

In February — just three months after Britney Schmidt proposed the possibility of subglacial lakes within Europa's thick ice crust — Russian scientists announced that they had drilled through the ice to reach Vostok.

In a first - of - its - kind feat of science and engineering, a National Science Foundation (NSF)- funded research team has successfully drilled through 800 meters (2,600 feet) of Antarctic ice to reach a subglacial lake and retrieve water and sediment samples that have been isolated from direct contact with the atmosphere for many thousands of years.

The data suggested that, like mountain glaciers, melt - induced glacier acceleration actually stops in years of intense melting once subglacial water erodes through the sediments and creates channels for water flow (Sundal et al. 2011).
