Crystal growth rates in polar firn / Hitoshi Shoji, Atau Mitani, Kohji Horita, Chester C. Langway, Jr.

Title: Crystal growth rates in polar firn / Hitoshi Shoji, Atau Mitani, Kohji Horita, Chester C. Langway, Jr.
Author(s): Shoji, Hitoshi.
Mitani, Atau.
Horita, Kohji.
Langway, Chester C.,
Date: 1993.
In: Annals of Glaciology. (1993.), Vol. 18 (1993)
Abstract: Continuous measurements made on Antarctic ice core (100 m deep) show enhanced growth rates above 30 m and between 70 and 80 m. Crystal growth in first zone probably takes place by sublimation and condensation, whereas higher growth rate in second zone is related to pore close-off transformation in which non-uniform strain field is created to form air bubbles by plastic deformation and "cannibalization" of individual ice crystals.
