View of the Drill Site D47

Caption

This is a general view of the drill site D47 in Antarctica where the LGGE (Laboratoire du Glaciologie et Geophysique de l'Environnement) team drilled one of two cores used in the recent Southern Hemisphere biomass-burning study. The thermal drilling method the researchers used allowed them to collect a 12-centimeter-diameter core, from which carbon monoxide and its isotopes were measured at Stony Brook University. These analyses required close to one kilogram of ice per sample.
