their goal was to assess fluctuations in ice mass But 3 years later they saw crevasses forming In the summer of 2007 they installed GPS receivers on metal stakes drilled into the glacier Then says Schuler "Things got more and more interesting" As the researchers reported in 2015 in The Cryosphere Austfonna’s movement accelerated each year in early July and slowed in late August Faster speeds broadly correlated with the number of days of above-freezing air temperatures But year after year after the glacier slowed in August its movement was faster than it had been before the speedup "It got pushed to a higher level every summer" Schuler says At the same time its crevasses were deepening and extending Suddenly in the autumn of 2012 the glacier failed spectacularly Over the following months it gushed 42 cubic kilometers of ice—enough to fill 17 million Olympic-size swimming pools—into the Barents Sea "It was the surge of the century" Schuler says Based on the correlation between warming and speedup Schuler and his colleagues suspect that the trigger for the surge was meltwater that trickled down through crevasses and accumulated at the glacier’s base summer after summer As the infiltrating water froze the latent heat it released warmed the surrounding ice "This alone can change glacier dynamics quite drastically" because warm ice flows a lot faster than its subzero counterpart Schuler says And as more water accumulated beneath Austfonna the increasing pressure like a hydraulic jack lifted the glacier from its bed Ultimately the cold ice anchoring Austfonna’s tongue to the ground disintegrated "That was the critical part that held the ice back" says Jon Ove Hagen a UiO glaciologist Its loss unleashed the surge Glaciers gain mass in their upper reaches where snowfall is heavier and lose it at their snouts where the ice breaks up and melts (right) Most glaciers flow steadily but some get stuck and accumulate mass (center) then release it in a surge A surging glacier can race down a valley or mountain growing thinner and longer (left) Then anywhere from days to years later the glacier’s speed ebbs and it begins thickening again Mud and debris flow Receiving area Sectional view Regular glacier Presurge Postsurge Ice front/snout Reservoir zone Crevasse Subglacial stream Terminal moraine Crevasse Ponding water Meltwater Sediment or rock Surging glaciers are riddled with crevasses especially in their lower reaches When the surge ends meltwater that built up under the glacier before the surge may sweep mud and debris from its snout Trickling down Meltwater plays a key role in triggering surges Pooling on the glacier’s surface it can seep down into crevasses There it can refreeze releasing heat that softens the ice; it can also pool at the base of the ice Steady state In a “normal” glacier meltwa- ter drains effi- ciently from its base carrying away heat and leaving the ice anchored to its bed Buildup to a surge If drainage is poor or melting accel- erates meltwater can accumulate under a glacier warming the ice and lifting it off the ground Aftermath Once the surge releases the meltwater the glacier subsides onto its bed and the cycle begins again Glacial surface down cracks in the ice Meltwater travels Ice Meltwater drain channel Steady meltwater flow under glacier releases heat and pressure Pooled meltwater Hydraulic lifting Ice warming Glacier settles Majority of meltwater expelled during surge A glacier unleashed Meltwater can freeze on its way down C BICKEL/SCIENCE Download this graphic The Austfonna study was a revelation "If water is important for triggering a surge—as we are increasingly realizing—then climate change must have an impact" says Heidi Sevestre a glaciologist at the University of St Andrews in the United Kingdom who was not involved in the study Analyses of the Aru surges also point to a climate link In western Tibet annual snowfall totals have risen steadily since the 1990s especially at higher elevations as strengthening westerly winds bring more precipitation "Glaciers are accumulating mass" Yao says "The bank accounts are getting fatter" Meanwhile average air temperatures in the region rose 15°C over the past 5 decades nearly twice the global average The warming has boosted the amount of meltwater shed by the Aru glaciers by 50% 3D computer modeling suggests "This means that more water can go through the cracks and eat the ice away" says Adrien Gilbert a UiO glaciologist who described his team’s findings at the Third Pole Science Summit last July in Kunming China Satellite imagery revealed new crevasses in the Aru glaciers in 2010 which grew deeper and more extensive summer after summer The final trigger for the surges may have been unusually heavy rains and snows during the 40 or so days before the first surge The precipitation "might be the straw that broke the camel’s back" says Yao who led a study of the Aru surges that appeared last February in the Journal of Glaciology The modeling by Gilbert’s team suggests that like Austfonna the Aru glaciers surged after their frozen tongues became unmoored "You need a huge amount of water to cause the failure" K? which Ishiguro wrote in just a month.
