For the reader in a hurry, the new Cuffey and Paterson fourth edition of The physics of glaciers defines the science of glaciers even better than the first three editions, and is a must-read for students and professionals in the field. During the International Glaciological Society’s Third International Symposium on Antarctic Glaciology in 1981 at The Ohio State University, where I was a student, the late, great Ian Whillans introduced me to Stan Paterson. We had a nice chat, and Stan asked some friendly but perceptive questions about my work with Ian on firn from Dome C. Afterwards, I asked Ian the key question, ‘Was that the W.S.B. Paterson?!?’ Then I ran off to tell my wife Cindy, who was helping with the meeting, that I had actually spoken to the Paterson, author of The physics of glaciers. For a student of glaciers then, the Journal of Glaciology (with the relatively new Annals) dominated the literature, but it was a jigsaw puzzle of information. Paterson supplied the picture on the puzzle box, putting the information into an orderly form that gave us confidence we could make sense of this wonderful field. Everything fit together in The physics of glaciers, with the key references and equations embedded clearly in text presented in lucid English, leading to the important applications. The book in many ways defined the field: ‘What is a glacier scientist?’ could be answered, ‘Someone who reads and contributes to the Journal and knows Paterson.’ Many a professor replied to the student question, ’Where can I find . . .?’, with the one-word answer ‘Paterson’. For later years, the professors had to supply a little additional information. In the Sherlock Holmes adventure The valley of fear (Doyle, 1914, chapter 1), the great detective was briefly stymied by a keyless cipher from his informant, Porlock, because Holmes and Watson had already updated their copy of Whitaker’s Almanack for the new year but Porlock was still using the old one. Similarly, detailed information required specifying which edition of Paterson was most relevant, the 1969 original, the 1981 second edition or the 1994 third edition. This was worth the effort, though: the updates closely tracked the rapid growth of the field. Furthermore, they offered the possibility that your research would be validated through citation by Paterson. But, as Stan appeared less frequently in the journals and at the meetings on glaciers, it seemed that the field had outgrown its definer. Numerous other valuable books were written, covering parts of the field in greater depth, or covering broader topics at a more introductory level, and a well-stocked library should include these. For advanced topics, I have often relied on Hooke’s Principles of glacier mechanics (now in its second edition, 2005), as well as Van der Veen’s Fundamentals of glacier mechanics (1999), the relatively new Dynamics of ice sheets and glaciers from Greve and Blatter (2009), and even the idiosyncratic view in Hughes’ Ice sheets (1998). Hambrey and Alean’s Glaciers (second edition, 2004), Benn and Evans’ Glaciers and glaciation (second edition, 2010) and Knight’s Glacier science and environmental change (2006) are among those that successfully cast broader nets. We have recommended many of these books to our students, and placed them on reserve in the library. But we still followed Paterson for our advanced students, while wondering whether it was proper to require a textbook more than a decade old in such a fast-changing field. Fortunately, Cuffey and Paterson’s fourth edition of The physics of glaciers solves the problem. This major rewrite of the classic text smoothly integrates the latest results with the bedrock of our field: roughly one-third of the material is new, one-third heavily revised and one-third lightly updated. The lucid, accessible presentation and the intellectual rigor of the earlier editions are not only preserved, but enhanced. At 693 pages plus references, this is not a light book, but the economy of presentation is noteworthy; others would have used many more words to say less. Consider, for example, figure 3.1, which merges adaptations of several of the diagrams from Hobbs’ (1974) Ice physics to explain the molecular structure of ice in a single half-page. The strong basis for adopting a dependence of strain rate on the stress cubed is well presented in section 3.4, together with a recalibration to more-accurate numerical values. Discussions of global warming often involve changes in glaciers, because they are so easy to see. But glaciers also figure prominently in misstatements about global warming, because so many processes are involved. The reality of modern discourse required a major upgrade to several sections of the text. For example, chapters 4 and 5 on massbalance processes deliver wonderfully for the serious student. Figure 4.6 by itself should go a long way toward removing confusion among those who are looking for answers. Note that this is not a reprint of someone else’s figure but a novel synthesis of diverse data from scattered sources that clarifies important concepts. Similar advances are scattered throughout the book; rather than simply reprinting a previously published figure in a ‘they said this’ review, the new book synthesizes and advances. Many of the individual pieces could have been published as stand-alone refereed papers. The careful reader will find numerous nuggets of wisdom, and jumping-off points for further research. For review material, the book relies heavily on comprehensive yet concise tables. Note, for example, the inclusion of relevant thermodynamic parameters for mass-balance modeling in table 5.1, the compilation of transfer coefficients for melting surfaces in table 5.5, the residence times for hydrological reservoir models in table 6.1, the long list of measured basal-slip rates of glaciers in table 7.1 and the drag factors in table 7.2 as part of the trove of useful information, carefully referenced, throughout the book. There are really too many other good parts to describe in this short review. A few more high points include:
