地球上海洋中水的质量分布的变化反过来又会导致其角动量的变化。在他的观点中，威尔逊讨论了马库斯等人在同一问题上提出的结果。其中射电天文技术被用来测量地球9号角动量的变化。这些变化是通过测量白天长度的变化来观察的，因此地球9号的自转速度也随之变化。这样的测量可以作为海洋行为的指标，就像其他指数被用来跟踪大气气候一样。
Changes in the mass distribution of water in Earth9s oceans in turn leads to variations in its angular momentum. In his Perspective, Wilson discusses results presented in the same issue by Marcus et al . in which techniques of radio astronomy were used to measure changes in Earth9s angular momentum. The variations were observed by measuring changes in the length of day, and therefore Earth9s rotation rate. Measurements such as these may serve as an indicator of oceanic behavior, much as other indices are used to keep track of atmospheric climate.
