Imaging of firn and bubbly ice in coaxial reflected light: a new technique for the characterization of these porous media

International audience A new technique for characterizing the structure of firn and bubbly ice is presented. This technique, based on observation of etched (sublimation) surfaces in coaxial reflected light, enables one to see simultaneously the pore network of the firn or bubbles in the ice and the...
