'This is a book that oceanographers (and meteorologists) concerned with internal waves will like to have on their bookshelves. It would also be valuable as a text for a graduate course, or for researcher wishing to start in this field...I enjoyed reading this text, and will continue to use it.' Journal of Geophysical, Astrophysical and Fluid Dynamics, 96:1 (2002) 'It is probable that here we may have a new classic in the field... Dynamics of Internal gravity Waves in the Ocean should be in the library of every fluid dynamicist and dynamical oceanographer or meteorologist.' Applied Mechanics Review, July 2002
