Moulton Gas Data

Data on the elemental and isotopic composition of O2, N2, Ar and CH4 are reported for three firn cores and two blu-ice cores from the Summit of Mt. Moulton. For the firn cores, we measured the firn air composition by sampling various levels within the firn as well as some measurements from the ice just beneath the firn/ice transition region. For the Blue-ice cores, we sampled the ice from the surface all the way to the bottom of the ice cores (~33mbs).
