In a new study, researchers propose a mechanism for how mega-canyons under northern Greenland’s ice sheet formed: from a series of catastrophic outburst floods that suddenly and repeatedly drained lakes of meltwater.

A student-led Cycle for Science trip will follow the footsteps of an ice sheet that buried the NYC area under a mile of ice during the last ice age.
Scientists aboard the R/V Joides Resolution prepare to set sail into the Southern Ocean.
Research by Lamont’s Johnny Kingslake and Elizabeth Case advances understanding of ice sheet dynamics and how our world may change in the coming centuries.
Joerg Schaefer and Gisela Winckler, scientists at Lamont-Doherty Earth Observatory, received funding from the Center for Climate and Life to examine the vulnerability of Greenland’s massive ice sheet.
Thousands of years ago, the West Antarctic ice sheet shrank dramatically—then grew back in an unexpected way.
Plus: Why they matter for climate change.
A study of ancient eruptions shows modern ice sheets could be vulnerable.
A new look inside the ice sheet validates predictions that it probably won’t melt as quickly as its neighbor—good news, since East Antarctica contains enough water to raise sea levels by 200 feet.
With its mission complete, the Rosetta-Ice Project will give scientists an unprecedented look at the Ross Ice Shelf and how it’s changing with the climate.
