This monograph provides a concise overview of nonlinear internal wave
theory. It serves as a self-contained reference for both students of
mathematics as well as scientific professionals by presenting the
material in two parts, isolating the narrative analysis from the
mathematical detail. This unique format allows the text to remain
accessible to oceanographers and researchers outside of mathematics by
presenting a range of relevant theories on their own terms. Conversely,
it enables applied mathematicians to understand how the conversation
between mathematics and sciences proceeds in a field that has developed
through a combination of the two. In addition, the text is supplemented
by hands-on Matlab software, as the book incorporates a collection of
working codes that enable readers to reproduce all theoretical figures
in the text, with modification potential to fit a range of applications
including a number of mini-projects outlined throughout the text.
