TL;DR: In this article, the authors used GPS data collected along a ∼35 km transect at the western margin of the Greenland ice sheet throughout a summer melt season to study the response of ice motion to seasonal variations in meltwater supply.

TL;DR: Satellite observations of ice motion recorded in a land-terminating sector of southwest Greenland are used to investigate the manner in which ice flow develops during years of markedly different melting, and a model of ice-sheet flow that captures switching between cavity and channel drainage modes is consistent with the run-off threshold, fast-flow periods, and later-summer speeds.

TL;DR: In the case of the Haut Glacier d'Arolla as mentioned in this paper, it was shown that the removal of snow from the glacier surface resulted in a dramatic increase in the volume of runoff into moulins, and in the peakedness of daily runoff cycles.

TL;DR: In this article, the authors present observations of changes in ice flow for all glaciers in High Mountain Asia over the period 2000-2017, based on one million pairs of optical satellite images.

TL;DR: Estimates of labile iron fluxes in meltwater are comparable with aeolian dust fluxes to the oceans surrounding Greenland and Antarctica, and are similarly expected to increase in a warming climate with enhanced melting.
