Record #112859:

Freezing-rate effects on the physical characteristics of basal ice formed by net adfreezing / Bryn Hubbard.

Title: Freezing-rate effects on the physical characteristics of basal ice formed by net adfreezing / Bryn Hubbard.
Author(s): Hubbard, Bryn.
Date: 1991.
In: Journal of Glaciology. (1991.), Vol. 37(127) (1991)
Abstract: Theoretical and empirical studies have indicated that many individual characteristics of ice formed by processes of net basal adfreezing may be sensitive to rate of propagation of freezing front through reservoir concerned. Effects of freezing rate on stable isotope chemistry and crystallography of ice, in addition to disposition and character of included debris and gas, are reported. Unidirectional freezing through cylindrical reservoir containing various water-sediment mixtures was conducted in laboratory, and resulting cores analyzed. Data lend support to inferences drawn from studies concerned with specific ice properties and idealized suite of characteristics is developed which may be diagnostic of basal ice formed by net freezing.
