科学家们绘制出了有史以来第一张沃斯托克湖水深地图。沃斯托克湖位于南极大陆冰盖下3700至4300米(超过两英里)的位置。大小大约相当于北美的安大略湖。对该湖最新的全面的测量表明,它分为两个截然不同的湖盆,两者的水体化学成分各不相同,并且具有一些其他的互不相同的特性。这些新的测量意义重大,因为它们提供了整个湖床的图像并表明该湖湖底有一个从前不为人知的北部附属湖盆,一道凸起的湖脊将其与南部的湖床分隔开来。通过激光测高仪、可穿透冰层的雷达及飞行器采集的重力测量信息,科学家估
The scientists mapped out the first depth map of Vostok Lake ever. Lake Vostok is located 3,700 to 4,300 meters (more than two miles) below the ice cover of the Antarctic continent. About the size of North Lake Ontario. The latest comprehensive survey of the lake shows that it is divided into two distinct lake basins, which have different water chemical compositions and some other distinct properties. These new measurements are significant because they provide an image of the entire lake bed and indicate that the lake has a previously unknown northern affiliated lake basin, and a raised ridge separates it from the southern lake bed. . Through the laser altimeter, radar penetrating the ice and the gravity measurement information collected by the aircraft, the scientists estimate
