Physical and chemical data from a firn aquifer in Southeast Greenland, 2015-2016

This dataset includes physical and chemical data from a firn aquifer upslope from Helheim Glacier collected in 2015 and 2016 to advance understanding of aquifers forming within the firn (compacted snow) of the percolation zone of the Greenland ice sheet. The dataset includes depth-specific tritium a...

Description
Summary:This dataset includes physical and chemical data from a firn aquifer upslope from Helheim Glacier collected in 2015 and 2016 to advance understanding of aquifers forming within the firn (compacted snow) of the percolation zone of the Greenland ice sheet. The dataset includes depth-specific tritium and chlorofluorocarbon-11 (CFC-11) measurements in aquifer liquid water and tritium in firn, dye concentration from a tracer experiment, and firn core stratigraphy. The tritium and CFC-11 data constrain aquifer age. The dye experiment provides information on meltwater movement through the unsaturated zone. Firn stratigraphy provides insight into snow accumulation and compaction, as well as melt patterns.
