| Abstract: | In this paper, three kinds of data assimilation schemes are presented at first. And then the adjoint method is introduced in detail. This paper also summarizes the applications of the adjoint method to the oceans in recent years. Finally, the paper suggests that the adjoint method will be a very useful and popular data assimilation scheme because of the development of satellite data. |
