在海洋学家中有这样一个说法:科学家对地球海底地貌的认识还不如对火星地貌的认识多。不过,这种观点可能很快就会改变。研究人员使用卫星测量地球重力场变化的数据,找到了更新而且更精确的海底地形图绘制方法。利用这种方法,已经能够识别以往无法识别的隐藏特征,解答地球古代史上一些悬而未决的疑问。之前,大约90%的深海海床没被绘制地形图。2014年3月,马航MH370失事后,人们认为它可能坠毁在南印度洋某处,但搜救者无法定位飞机残骸的位置。这种尴尬更让深海海床地形图
There is a saying among oceanographers that scientists are not as good at understanding the Earth’s seabed as it does at Mars. However, this view may change soon. Researchers used satellite data to measure changes in the Earth’s gravitational field to find newer and more accurate methods of mapping seafloor topography. Using this method, it has been possible to identify previously unrecognized hidden features and answer some of the outstanding questions in the ancient history of the earth. Before that, about 90% of the deep seabed was not mapped. After the MH370 crash in March 2014, it was thought that it might crashed somewhere in the South Indian Ocean, but search and rescue workers could not locate the wreckage of the aircraft. This embarrassment more let the deep seabed topographic map
