The Watson River drains a portion of the Southwest Greenland Ice Sheet.
How water moves here between the surface of the ice, and eventually, the ocean, is a significant question for scientists to explore, in order to understand accelerating sea level rise.
My guide Dr. Asa Rennermalm, of Rutgers, showed me the way from Ocean to ice sheet.

Go to sleep. Do you know what time it is?
But the sun is still up! 😛
