The influence of closed brine pockets and permeable brine channels on the thermo-elastic properties of saline ice
A model of the thermo-elastic behaviour of saline ice is formulated, and model solutions describing thermo-elastic waves propagating into a half-space of the ice are investigated.

Summary: | A model of the thermo-elastic behaviour of saline ice is formulated, and model solutions describing thermo-elastic waves propagating into a half-space of the ice are investigated. The model is based on a proposal that saline ice is a matrix which encompasses both closed brine pockets and permeable channels filled with brine. Experiments on the thermal expansion of saline ice samples, and on thermo-elastic waves in saline ice, have been performed in the cold laboratories of the University Centre in Svalbard and in University College London. The experimental data are compared with theoretical conclusions. The experimental data support our hypothesis that the brine in saline ice is divided between closed pockets and open, permeable channels. |
