南极拉斯曼丘陵重力基准的建立

Establishment of Gravity Base over Larsemann Hills in Antarctica

摘要: 2008～2009年南极夏季期间,中国第25次南极科学考察队利用A-10便携式绝对重力仪和LaCoste&Romberg G相对重力仪在南极中山站及附近拉斯曼丘陵地区建立了高精度重力基准网。该网由3个绝对重力点和10个相对重力点组成,其绝对和相对重力测量的精度分别优于7.5×10-8 m.s-2、20×10-8 m.s-2。

Abstract: During the Antarctic summer of 2008-2009,China's the 25th Antarctic scientific expedition team established the high precision gravity base network over Zhongshan Station and its neighboring area Larsemann Hills in Antarctica,using A-10 portable absolute gravimeter and LaCoste & Romberg G relative gravimeter.The network is composed of three absolute gravity stations and 10 relative gravity points.The accuracy of absolute and relative gravimetry is better than 7.5×10-8 m·s-2 and 20×10-8 m·s-2 respectively.
