Barrels of ancient Antarctic air aim to track history of rare gas

  • Researchers at the University of Washington and the University of Rochester are part of a team working to trace a much rarer gas, present at less than one in a trillion molecules.
  • The heavy snow accumulation at Law Dome means plenty of air bubbles per year, and provides a thick enough shield to protect the carbon-14 monoxide from solar radiation.
  • Analysis over the coming months will aim to produce a concentration curve for carbon-14 monoxide and hydroxyl over the decades, similar to the now-famous curves for carbon dioxide and methane.
