Oceanic Migration studies the prehistoric peopling of the Pacific. It uses science and mathematics to expand the research base of Pacific prehistory and casts new light on this final human expansion. It explores the fundamental roles of oceanography and of global climate change in determining the paths, sequence, timing and range of Spice Island-based maritime migrations ranging across a quarter of the globe.

The book is of interest to Pacific prehistorians, oceanographers and American anthropologists concerned with the diffusionist debate. For oceanographers it presents the new idea of the role of the West Pacific Warm Pool and of three of its four major currents in determining the evolution of voyaging in two oceans. For diffusionists it provides new chronological and technological contexts in which the issue of diffusionism needs to be reconsidered. For prehistorians it creates a paradigmatic shift by establishing a new time depth and mechanism for Polynesian exploration, offers a new view of voyaging and exploration strategies and of economic imperatives and adds a new dimension to the debate on Polynesian origins.
