Glacier shape can predict melting risk
Analysing how glaciers are shaped can help scientists identify which one of them are susceptible to thinning, says a study.
​Washington: Analysing how glaciers are shaped can help scientists identify which one of them are susceptible to thinning, says a study.
Just how prone a glacier is to thinning depends on its thickness and surface slope, features that are influenced by the landscape under the glacier, said the study published in the journal Nature Geoscience.
The research could help predict how much the Greenland Ice Sheet will contribute to future sea level rise in the next century, a number that currently ranges from inches to feet.
The Greenland Ice Sheet is the second largest ice sheet on Earth and has been losing mass for decades, a trend scientists have linked to a warming climate.
We were looking for a way to explain why this variability exists, and we found a way to do it that has never been applied before on this scale," said lead author Denis Felikson, a graduate research assistant at The University of Texas Institute for Geophysics (UTIG) in the US.
Of the 16 glaciers researchers investigated in West Greenland, the study found four that are the most susceptible to thinning: Rink Isbrae, Umiamako Isbrae, Jakobshavn Isbrae and Sermeq Silardleq.
