作为国际地球物理年计划的一部分，也是国际地球物理年的后续计划，美国正在南极洲开展一项广泛的导线计划。七次主要的积雪穿越，加上几次较短的旅行和一次空中穿越，迄今已在费尔奇纳和罗斯冰架、玛丽·伯德兰、埃尔斯沃斯高地和南极洲东部的维多利亚陆地高原覆盖了超过12,000公里(图1)。这些穿越的科学计划综合了对冰盖上层的冰川学调查和地震、重力、磁力和高程研究，以确定冰层厚度、冰盖的物理特征和冰下岩层的性质。从这项工作中，现在已经出现了一个相当清楚的南极洲西部结构的轮廓。
As part of its program for the International Geophysical Year and the IGY's successor, International Geo-physical Cooperation, the United States is conducting an extensive traverse program in Antarctica. Seven major oversnow traverses, supplemented by several shorter trips and one airborne traverse, have thus far covered over 12,000 kilometers on the Filchner and Ross ice shelves, Marie Byrd Land, the Ellsworth highland, and the Victoria Land plateauof eastern Antarctica (Fig. 1). The scientific program of these traverses comlprised glaciological investigations of the upper layers of the icecap and seismic, gravity, magnetic, and elevation studies to determine ice thickness, the physical characteristics of the icecap, and the nature of the rock floor beneath the ice. From this work a fairly clear outline of the struc-ture of West Antarctica has now emerged.
