Laboratory studies of the flow of ice

Metadata record for data from ASAC Project 8 See the link below for public details on this project.This project studies the fundamentals of how ice flows. The project is carried out primarily in the Hobart laboratories, and involves experiments in which ice samples from Antarctica are loaded under various stresses at different temperatures. The ice samples are selected with a range of crystal sizes, crystal orientations, impurity content, etc. so that the effect of each of these properties on the flow of the ice can be measured.The ice flow within the Antarctic Ice Sheet is governed largely by the deformation of the ice near the base. It is thus essential to understand the flow processes in the basal ice to accurately model the Antarctic Ice Sheet mass balance. Therefore, over the next 3 years,this project will carry out measurements at warm temperatures, of the flow rates of silty ice similar to that found at the base of the ice sheet.Records for this work have been archived at the Australian Antarctic Division.

本数据集为ASAC项目8号的元数据记录，有关该项目的公开详情请参阅下方链接。本项目聚焦冰体流动的基础机理研究，主要依托霍巴特实验室开展实验。实验内容为在不同温度与多种应力条件下对取自南极洲的冰样施加荷载。实验选用的冰样涵盖一系列晶粒尺寸、晶体取向与杂质含量等参数，以此量化各属性对冰体流动的影响。南极冰盖（Antarctic Ice Sheet）内部的冰体流动主要受控于冰盖底部附近的冰体变形，因此若要精准构建南极冰盖物质平衡模型，明晰底部冰体的流动过程至关重要。为此，本项目将在未来3年内，于暖温环境下测量与冰盖底部赋存的粉砂质冰相似的冰样的流动速率。本项研究的相关记录已归档于澳大利亚南极局（Australian Antarctic Division）。实验日志：《冰川学 冰压缩与冰晶日志》（GAO）—— 收录野外冰压缩实验的各类记录与结果笔记，内含冰晶照片。
