Firn on ice sheets

Most of the Greenland and Antarctic ice sheets are covered with firn — the transitional material between snow and glacial ice. Firn is vital for understanding ice-sheet mass balance and hydrology, and palaeoclimate.

Atmospheric trends of the halon gases from polar firn air

, 2005
International audienceFour halons (H-1301, H-1211, H-2402 and H-1202) have been measured in air samples collected from polar firn from Dome Concordia (Dome C), Antarctica, from Devon Island, Canada and the North Greenland Ice Core Project (NGRIP) site ...

Densification and Recrystallization of Firn at Dome C, East Antarctica

, 1980
This study reports on variations of density, crystal size, and crystal shape-with-depth to 50 m for Dome C, central East Antarctica. The critical point in the depth-density profile is less sharply defined than at other locations.
