Short-wavelength anomalies in sea surface topography, caused by the gravitational effects of major ocean bottom topographic features, have been detected by the radar altimeter aboard Skylab. Some features, such as deep ocean trenches, seamounts, and escarpments, displace the ocean surface by as much as 15 meters over 100-kilometer wavelengths. This experiment demonstrates the potential of satellite altimetry for determining the ocean geoid and for mapping major features of the ocean bottom.
由主要大洋底部地形特征的引力效应引起的海面地形短波异常已被 Skylab 上的雷达高度计探测到。一些特征，如深海海沟、海山和悬崖，在 100 公里波长上使海面位移达 15 米之多。该实验证明了卫星测高术在确定海洋大地水准面和绘制大洋底部主要特征方面的潜力。
