Freezing-rate effects on the physical characteristics of basal ice formed by net adfreezing
Abstract A number of theoretical and empirical studies have indicated that many individual characteristics of ice formed by processes of net basal adfreezing may be sensitive to the rate of propagation of the freezing front through the reservoir concerned. The effects of freezing rate on the the sta...
