Measurements of surface energy of air-hydrate crystals in Vostok ice core, Antarctica / Tsutomu Uchida, Shinji Mae, Takeo Hondoh, Paul Duval, Volodya Ya. Lipenkov.
Title: | Measurements of surface energy of air-hydrate crystals in Vostok ice core, Antarctica / Tsutomu Uchida, Shinji Mae, Takeo Hondoh, Paul Duval, Volodya Ya. Lipenkov. |
Author(s): | Uchida, Tsutomu. Mae, Shinji. Hondoh, Takeo. Duval, Paul. Lipenkov, Volodya Ya. |
Date: | 1993. |
In: | National Institute of Polar Research. Proceedings of the NIPR Symposium on Polar Meteorology and Glaciology. (1993.), Vol. 7 (1993) |
Abstract: | Observations showed that various shapes and sizes of clathrate air-hydrate crystals are located on grain boundaries. Surface energy of 41 air-hydrate crystals in ice cores at seven depths was measured. Measurements revealed that surface energy was almost constant at all depths below 1050 m, and that average ratio between surface energy of air-hydrate and ice grain boundary energy was 0.97±0.19. |
