中文摘要
该项目支持完成冰的摄影测量 南极洲的溪流B。 本工作的成果包括:1)准确 排放计算,以完善质量平衡测定,2) 描述流动扰动以显示冰的影响 河流两侧和控制流量的基本特征,以及3) 计算用于绘制基线地图的部队预算 阻力和滑动速度,可以解释为基础 力学 集水区的调查也即将完成。 的 该地区的界限将得到更好的界定,积累率 绘制了地图,并获得了沿着 选定的流动带。 这些数据是必要的准确 西南极冰盖的质量平衡计算。 实地工作将于一九八八至八九年度进行,而资料整理工作则于 1989-90.
英文摘要
This project supports the completion of photogrammetry of ice stream B, Antarctica. Products of this work include: 1) accurate discharge calculations to refine mass balance determinations, 2) description of flow disturbances to show the influence of ice stream sides and of basal features in controlling flow, and 3) calculations of force budget for the production of maps of basal drag and sliding velocity that can be interpreted in of basal mechanics. The survey of the catchment area is also to be completed. The limits to the area will be better defined, accumulation rates mapped, and accurate divergence measurements obtained along selected flow bands. These data are necessary for the accurate calculation of the mass balance of the West Antarctic Ice Sheet. Field work is to be conducted in 1988-89 and data reduction in 1989-90.
