Sulfur hexafluoride (SF6) traces of Moulin L41A on the Greenland Ice Sheet measured in summer 2012 ...
SF6 gas traces were injected into Moulin L41A, and samples were collected in the proglacial river near Leverett Glacier terminus (67.09N, -50.23E). A total of 11 traces were carried out between 16 June and 6 August, 2012. Tracers were injected at ~19:00 hrs, shortly after the peak daily moulin disch...
