Stommel和Schott和Wunsch最近提出的水文观测推断绝对速度的方法进行了比较，发现是基于等效动力学的复杂性。的方法中的差异示出的准稳态大尺度信号的尺度和变异性或噪声的不同假设的结果。提出了噪声的客观计算方法。
Methods for inferring absolute velocity from hydrographic observations recently advanced by Stommel and Schott and by Wunsch are compared and found to be based on equivalent dynamical sophistication. The differences in the methods are shown to result from differing assumptions about the scales of the quasi-steady large-scale signal and the variability or noise. An objective method of accounting for the noise is advanced.
