In this data set we present trace gas measurements and derived variables such as basal glacial meltwater (GMW) fractions and water ages. The trace gases comprise the lighter noble gasses, i.e., total helium (He) and the excess above solubility equilibrium ΔHe, the 3He/4He ratio reported as δ3He, total neon (Ne) and the excess ΔNe, and the deviation from the equilibrium He/Ne ratio Δ(He/Ne), as well as the transient anthropogenic trace gases chlorofluorocarbon (CFC-12) and sulphur hexafluoride (SF6) concentrations. From these noble gases He and Ne we derived glacial meltwater fractions. From the transient tracers we computed SF6-concentration ages, CFC-12/SF6 ratio ages and TTD mean ages.
