Among the most significant: a previously unmeasured acceleration of glacier flow into Antarcticas Getz Ice Shelf, on the southwestern part of the continent -- likely a result of ice-shelf thinning.
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.
The settlement on glacier flow path is at high risk which should immediately be moved to a safer zone, he recommended.
Some of the loss has been attributed to accelerated glacier flow towards ocean outlets.
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.
These results will be connected to global-scale glacier dynamics, for which a global set of repeat optical and radar satellite images will be processed to measure displacements due to glacier flow and their annual to decadal-scale changes.
Construct and observe the simulation of a glacier flow / landslide.
We think that warm ocean currents reaching the coast and melting the glacier front is the most likely cause of faster glacier flow," said lead author Dr Hamish Pritchard from British Antarctic Survey (BAS).
Meltwater creeks from the nearby Myrdalsjokull glacier flow around the moss-covered, 100-metre-high volcanic cone, which emerged after an eruption beneath several hundred metres of ice during the last ice age; Below: ice and snow cover Lake Thingvallavatn in Thingvellir National Park in the southwest of Iceland.
These goals have one thing in common: due to glacier flow most of this record will only be found in a very thin layer in the bottom-most ice of the cores.
