An unstable Greenland glacier suddenly raced toward the sea

"As tidewater glaciers, Such as Jakobshavn Isbræ, then They become sensitive to small variations in ice thickness," researcher Ryan Cassotto.

New research helped scientists understand the strange behavior Of a de-stabilized Greenland glacier.

Scientists now know why an unstable Greenland glacier Abruptly rushed toward the ocean and then slowed, only days after.

Researchers employed detailed observations of behavior

Following a sunken fracture caused the glacier to The glacier started to slide into the sea at accelerating speeds. Scientists measured the glacier moving at speeds three times that the rates listed in previous decades.

But Rather than moving just like a runaway train, even in a terminal Fashion, the glacier accelerated for several days and then suddenly slowed. A new study of the event suggests the progressive reduction of the glacier caused the ice to slide in increasing speeds, but a pileup of ice helped to reestablish the glacier's terminus and slam on the breaks.
Assess the speed and deformation of freezing ice with unprecedented detail. The observations showed small changes at the bottom of a glacier could have significant consequences on the glacier's speed.

Help scientists accurately predict the consequences of melting tidewater glaciers on global sea level increase.

"As tidewater glaciers, such as Jakobshavn Isbræ, afterward "This is because water pressure at the base of this glacier counters pressure by the weight of ice, which affects how fast the glacier flows"

Cassotto now functions as a researcher at Cooperative Institute For Research in Environmental Sciences, sponsored at the University of Colorado Boulder and NOAA, but studied that the Jakobshavn glacier as a doctoral student at the University of New Hampshire.

"Over the last two decades, Jakobshavn Isbræ has Discharged more ice than some other glacier in Greenland," explained Cassotto. "It alone results from roughly three percent of their current rise in global Sea level every year."
