AN IN SITU GAS EXTRACTION SYSTEM FOR RADIOCARBON DATING GLACIER ICE.
In March 1966 at the Tuto ice tunnel, Greenland, a team from USA CRREL and the University of Bern tested a new down-borehole device which would allow gas to be extracted from within shallow or deep boreholes. The tunnel ice was unfractured and its temperature was constant at -10C. A location where,...
