Based on the theory of precipitation from supersaturated solutions proposed by Lifshitz and Slyozov (J. Phys. Chem. Solids 19 (1/2) (1961) 35), we develop a mathematical description of post-formation growth (ripening) of ...

A mathematical model for simulating the densification of bubbly glacier ice is used to interpret the following experimental data from the Vostok (central Antarctica) ice core: two ice-porosity profiles obtained by independent ...

An interpretation of the deuterium profile measured along the Vostok (East ANtarctica) ice core down to 2755 m has been attempted on the basis of the borehole temperature analysis. An inverse problem is solved to infer a ...

We present an attempt to model the process of conversion of an air bubble, trapped in ice, to clathrate air-hydrate crystal after its nucleation on the air-ice interface. Both counterparts of the transformation are considered: ...

A recently developed theory of post-nucleation conversion of an air bubble to air-hydrate crystal in ice is applied to simulate two different types of air-hydrate formation in polar ice sheets. The work is focused on ...

Several sets of temperature measurements were carried out in 1972-88 in the Vostok boreholes. They have provided the ice-sheet temperature profile down to a depth of 2000m. The accuracy of the profile is sufficient to ...
