Here’s the first picture from our expedition to Greenland. I am standing on the edge of one of the four moulins we found at the bottom of the supraglacial lake that, among other things, we studied this year. The lake drained in ~ 1.5 hours ! More visual material, including a time lapse of the draining lake and more stills of our expedition, will be coming soon. High-resolution of the picture is available upon request.
