Once broken away, these icebergs will leave weaker ice shelves behind, leading to faster glacier flow
from the continent and by that pushing up sea levels.
The settlement on glacier flow
path is at high risk which should immediately be moved to a safer zone, he recommended.
Changes in the location and amount of meltwater refreezing within the surface layers of the ice cap will affect ice temperature and viscosity, with eventual consequences for glacier flow
rates; more recent studies, therefore, include spatially distributed predictions of the annual amount of internal refreezing from 1980 to 2006 (Gardner and Sharp, 2009).
Understanding this network is important, said the paper, as it can lubricate glacier flow
and send the ice speeding toward the ocean, where it can melt and contribute to sea-level change.
The existence of subglacial tectonic faults and valleys, which coincided with the glacier flow
direction, but esker formation was not a direct result of the Late-Glacial neotectonic movement in the glacial-subglacial environment.
Is this variability due to the forces of external climate on the great ice sheet or is it due to natural and episodic instabilities that arise from the forces that control complex glacier flow
? The new velocity measurements from the second mission will help answer that question.
Although glacier flow
has increased since the 1990s, scientists from University of Leeds have found the melting rate to be only around a third of what was previously projected.

Some of the loss has been attributed to accelerated glacier flow
towards ocean outlets.
