%Surface ice samples (~50 grams each) were collected from 5-10 cm below the ice surface at 10 m interval between the flagged waypoints (listed as Site Numbers -
%coordinates provided) of a transect (A-B) through the main icefield. Ice samples were processed at McMurdo Station's Crary Laboratory using the following
%procedure: Each sample was melted in a sealed plastic bag at room temperature, vigorously shaken, then decanted into an 18 ml plastic scintillation vial. As an
%extra precaution against evaporation during shipment, the scintillation vials were sealed with both paraffin wax and electric tape. The sealed samples were refrozen
%and shipped to the University of Maine where they remained frozen (below -10C) until the time of analysis. All samples analyzed between February and April of 2010
%at the University of Maine Climate Change Institute for d18O via equilibration with CO2 gas at 25C. Equilibrated gas was admitted from a Micromass Multiprep
%peripheral to a VG SIRA dual inlet mass spectrometer for measurement (±0.5 per mil precision). Isotope ratios are normalized on the V-SMOW / SLAP scale.
%
%*Distances are in km from Site 1
%Age is from 2013 version of the time-scale established in Spaulding et al., 2013.
