Sentences with phrase «subglacial drainage»

In contrast to the modern glacial setting, these lithofacies require the development and maintenance of a well - organized subglacial drainage network during deglaciation.

Melt - induced speed - up of Greenland ice sheet offset by efficient subglacial drainage.

Shifts in subglacial drainage patterns change the location of these basal channels, which could impact the ice shelf's stability by unevenly distributing the melting at the base.

«The location of the melting strengthens the idea that freshwater from the local subglacial drainage system is responsible for the evolving ice shelf features.»

Not exact matches

The peak drainage rate was about 8,500 cubic feet (240 cubic meters) per second, about half the flow of the Hudson River — the largest meltwater outflow yet reported for subglacial lakes in this region.

We conclude that the ice sheet surface is efficiently drained under optimal conditions, that digital elevation models alone can not fully describe supraglacial drainage and its connection to subglacial systems, and that predicting outflow from climate models alone, without recognition of subglacial processes, may overestimate true meltwater release from the ice sheet.
