From the reviews: "A strong understanding of Lagrangian approaches to the transport and stirring of fluid often benefits from mental visualization. One must picture diverging fluid and evolving material curves that deform and tangle about each other. A successful introduction to this subject should facilitate this description, and this fine monograph by Roger Samelson and ... Read moreSteve Wiggins does so effectively. The book is written primarily for students and researchers in the geosciences." (Larry Pratt, SIAM Review, Vol. 49 (4), 2007) "Samelson and Wiggins aim to provide an accessible introduction to modern mathematical techniques to explore transport and exchange in geophysical flows. … The book is very well structured. … Each chapter has a good introduction and concludes with a good summary. The book undoubtedly reads well. … The four appendices provide interesting extra information. The two page index is adequate. Over nine pages of references ensures the bibliography provides valuable pointers into recent research. … In summary: lovely material, well written … ." (Anthony John Roberts, Mathematical Reviews, Issue 2008 f) "The purpose of the monograph is to explore some of the new insights into Lagrangian motion in geophysical flows followed from such approach and to present an accessible introduction to the basic elements of some of these methods. … The monograph will be useful for applied mathematicians, especially working in geophysical fluid dynamics."
