L087, Ice Thickness Measurement by seismic and gravimetric methods, Antarctica, 1957, 1958

The report describes work carried out during an ice thickness survey by seismic and gravimetric methods made in the summer of 1957-58 in MacRobertson Land, Antarctica. Methods used during the survey are described and the equipment used is listed in detail. Results have not yet been analysed fully but preliminary profiles are given. The accuracy limits applying to these profiles are given and future extensions of the calcu18tions are discussed.

本报告详述了1957-1958年夏季于南极洲麦克罗伯逊地（MacRobertson Land）开展的冰厚调查工作，本次调查采用地震与重力测量法。报告对本次调查所使用的方法进行了说明，并详细罗列了所用的仪器设备。目前尚未对全部调查结果完成系统性分析，但已提供初步剖面数据。同时明确了上述剖面数据的精度限差，并讨论了后续计算工作的拓展方向。
