Depth-Time-Temperature Relationships of Ice Crystal Growth in Polar Glaciers.
Abstract
The growth of ice crystals as a function of depth and time in polar firn and glacier ice has been investigated at a number of locations in Antarctica and Greenland. Thin sections of snow and ice were used to measure crystal size variations. Crystal growth rates are strongly temperature dependent with growth being very much retarded at the lower englacial temperatures. At Camp Century, Greenland, where the firn temperature is -24C (constant below 10 m depth) crystals grow approximately 23 times faster than at Plateau Station, Antarctica, where the in situ temperature is -57C.
