What a Glacial River Reveals About the Greenland Ice Sheet

Five years after a NASA-funded field study returned to to set up camp once again in the melt zone of the Greenland Ice Sheet, a new study adds to the rich findings from this innovative project. We look back on this bold undertaking, which featured helicopters, floating drifters plunging into holes in the ice, and all-night shifts operating a sonic boogie board under endless daylight. Scientist Larry Smith, at the time with UCLA and now with Brown University, takes us back to the challenges on the ice and the important findings made with the hard-won data.

At the fringes of the Greenland Ice Sheet, where glaciers are constantly melting, water rushes everywhere through an intricate system of lakes and streams that branch out like slip and slide shoots of super chilled, bright turquoise water. Some of that water eventually cascades straight into the surrounding land and ocean through channels and cracks. Some of it thunders off into sinkhole-like structures on the ice called moulins. Rumbling 24 hours a day, these holes swallow water from the surface and funnel it to the bedrock at the base of the ice.

By now you have probably heard of SonTek's latest and greatest ADCP - the RS5. This hand-sized, grab-and-go instrument and is ideal for collecting discharge data in small rivers and streams. But if you're already a SonTek customer, or familiar with the acoustic Doppler technology in general, you might ask yourself, why would I use the RS5 when I already have another system like a RiverSurveyor-M9, or maybe even a FlowTracker. Well in this video, we're going to give you 5-and-a-half reasons why you would want to go with the RS5 over other flow sensors.
