一个相当于5个洞庭湖那么大的湖泊在南极洲冰层下面隐藏着。这个大湖位于南极洲中央偏东的俄罗斯沃斯托克钻冰站的下面,人们称它为沃斯托克湖,它是迄今巳知的南极洲77个湖泊中最大的一个。在1974～1975年间,一个对冰层深处的勘测试验发现了这个湖的存在。随后,一些研究者用无线电回波对它的边界进行了探测。那时,人们估计湖的总面积为10000平方公里。直到1993年,来自人造卫星上测高仪的数据才提供了这个湖的大小、范围等确切数据。去年,剑桥大学的格尔顿·洛滨等三位英国科学家和两位俄罗斯地球
A lake as large as five Dongting Lake is hidden beneath the Antarctic ice sheet. Located below Vostok, Russia, east of Antarctica, this large lake is called Lake Vostok, the largest of 77 so far known to Antarctica. During 1974-1975, a deep investigation of the ice found the existence of the lake. Subsequently, some researchers used radio echo to detect its boundary. At that time, it was estimated that the total area of the lake was 10,000 square kilometers. Until 1993, the data from the satellite on the altimeter provided exact data on the size and extent of the lake. Last year, three British scientists, including Gert Erlobin of Cambridge University and two Russian scientists
