For more than two decades our lab has analyzed air from the layer of compressed snow, called firn, that covers polar ice sheets. This year I could finally join a field campaign to the Greenland ice sheet myself.
The trip there took longer than expected, because of a very warm period in Greenland in the beginning of June. The snow at the East Greenland Ice-Core Project (EGRIP) camp was so soft that the heavy Hercules C130 cargo aircraft would not be able to take off after landing. So, we were stuck for four days in Kangerlussuaq west Greenland. We spent the time packing and preparing, but also made a very nice trip to the Russel glacier.
