The European Project for Ice Coring in Antarctica (EPICA) Dome C ice core (75°06’S, 123°21’E) extends back eight glacial cycles, or approximately 800,000 years26 Parameters including temperature (stable isotopes), aridity (dust concentrations), and atmospheric chemistry (trace elements and major ions) have already been quantified through the length of the core. In addition, EPICA community members measured greenhouse gasses (CO2 and methane) in bubbles trapped in the ice matrix which provide insight into the composition of past atmospheric composition26. Antarctic ice cores supply a hemispheric signal of atmospheric chemistry and fire activity which provide a comparison to the polar and mountain ice cores presented here. We are analyzing a high-resolution record of biomass burning for the past 10,000 years in the EPICA Dome C ice core.
