A
"glacier tongue" refers to a long piece of ice that sticks out from a glacier and resembles the shape of a tongue.
Full definition
A healthy glacier has an accumulation zone at high elevations and an ablation zone at lower elevations; ice flow from the accumulation zone continually
feeds glacier tongues that penetrate into the ablation zone.
Contrary to the aforementioned report, a recent study by Gardelle and others (2012) reveals that high rates of ice loss can occur on debris -
covered glacier tongues (12).
The corresponding increased ice sheet mass loss has often followed thinning, reduction or loss of ice shelves or loss of
floating glacier tongues.
The Krossá snaked silvery - gray through the floodplain below, and
the glacier tongues of the Mýrdalsjökull lapped down from the mountains opposite us.
«The most plausible sequence of events is that the thinning eventually reached a threshold, ungrounded
the glacier tongues and subsequently allowed acceleration, retreat and further thinning.
Interaction with the ocean occurs at the undersides of the floating ice shelves and
glacier tongues, and consequent changes in thickness affect the rate of ice flow from the grounded ice.
Glaciers in the Pamir Mountains of Tajikistan are generally retreating while further south, behaviour of the Karakoram glaciers is mixed, but lacking wholesale, rapid disintegration of
glacier tongues and rampant lake growth.
