Greenland Firn Aquifer Project Battles Tremendous Snowfall

In late March, IDDO engineer Josh Goetz deployed with the Greenland Firn Aquifer project science team (Forster, PI) to Kulusuk in Southeast (SE) Greenland. After issues with poor weather and with helicopter availability, the team made it into the icecap in SE Greenland and drilled the first of four planned holes into the firn aquifer layer. A thermistor string was placed in the borehole, and while the plan was to then move to a second site, an unusually heavy pair of storms descended upon the camp, dropping approximately 2.5 meters of snow in just five days, precluding movement to the second site. Shown in the photo below, snow has completely covered the drill winch and nearly half of the 3.2 meter tall drill tower. It is surmised that the first storm encountered was the remnant of a hurricane that formed off the coast of Newfoundland.

The thermal drill covered in snow in SE Greenland.

A spring storm brought ~2.5 m of snow to the Greenland Firn Aquifer project camp.
