Scientists said Monday they had used a drone to observe the rapid fracturing and draining of a lake on the Greenland ice sheet, a phenomenon that may become more frequent as a result of climate change.
This process has been extremely difficult to observe firsthand, but a group of glaciologists from the Scott Polar Institute at the University of Cambridge were fortunate when they arrived at the Store Glacier in northwest Greenland in July 2018. Tom Chudley, co-first author of the study that appeared in the Proceedings of the National Academy of Sciences told AFP that the"thing that drones can do is allow us to take these kind of high quality measurements in regions that aren't safe to access for scientists on the ground."
"That's a kilometer of ice lifted up half a meter, so you can imagine the kind of pressures that were involved," said Chudley, a doctoral student at Cambridge.
