Lakes on Greenland Ice Sheet can drain huge amounts of water, even in winter
Using satellite data to ‘see in the dark’, researchers have shown for the first time that lakes on the Greenland Ice Sheet drain during winter, a finding with implications for the speed at which the world’s second-largest ice sheet flows to the ocean.
We don’t yet know how widespread this winter lake drainage phenomenon is, but it could have important implications for the Greenland Ice Sheet, as well as elsewhere in the Arctic and Antarctic Ian Willis
The researchers, from the University of Cambridge, used radar data from a European Space Agency satellite to show that even when the heat from the Sun is absent, these lakes can discharge large amounts of water to the base of the ice sheet. These ‘drainage events’ are thought to play a significant role in accelerating the movement of the ice by lubricating it from below.

LONDON (AP) A sled and flag used in one of explorer Ernest Shackleton s famed expeditions to the South Pole have been bought by a British government-funded body to keep the treasured artifacts in the U.K.
The National Heritage Memorial Fund, a government-funded body, said Wednesday that it paid 204,000 pounds ($274,000) to help purchase the two items, used in the first of three British Antarctic expeditions led by Shackleton in the early 1900s. The artifacts will be donated to two English museums.
Earlier this year, British authorities slapped a temporary export ban on the artifacts.
The expedition was named Nimrod after the ship, which came within less than 100 miles (160 kilometers) of the South Pole for the first time in 1909. But before reaching their target, the explorers were forced to turn back, having stretched their rations to the limit.
