1982年10月我参加了北伊利诺大学L.D.McGinnis教授在南极的研究项目,于25日到达南极McMurdo基地进行了49天的野外考察,完成了一条50公里长的人工地震测深剖面。然后,我与新西兰的Tim Stern博士等一起,乘直升飞机,分别完成了Ross岛上的重力测量,取得了十个点上的重力资料。于1982年12月13日飞回新西兰。现仅就我所接触到的一些南极资料和研究课题简介如下: 关于地震研究 南极大陆和周围海域通常称为南极板块,是世界上最大的无震活动区之一。1957年的国际地球物理年以后,在南极大陆已经布设了十几个台站。但到目前为止,除了火山活动之外,世界地震
In 1982 October I participated in the South Illinois University L.D.McGinnis Professor Antarctic research project, arrived in the Antarctic on the 25th McMurdo base for 49 days of field trips, completed a 50 km long artificial seismic sounding profile. Then, together with Dr Tim Stern of New Zealand, I took the helicopter to complete the gravimetric survey on Ross Island separately and got the gravity data at ten spots. Flew back to New Zealand on December 13, 1982. Here are just a few of the Antarctic data and research topics I have come across as follows: About Seismic Studies The Antarctic continent and the surrounding sea, often referred to as the Antarctic Plate, is one of the largest seismically active areas in the world. After the International Geophysical Year 1957, more than a dozen stations have been deployed in the Antarctic continent. But so far, in addition to volcanic activity, the world earthquake
