P(論文) In the polar region, during the process of snow-firn-ice transition, the air in the snow is isolated from the atmosphere and enclosed in the ice as bubbles. The trapped air is expected to contain trace gases which represent the atmospheric concentrations at the time of ice formation. In order...
