[2] His 2013 book, The Great Ocean: Pacific Worlds from Captain Cook to the Gold Rush, published by Oxford University Press in April 2013[3] is a study of the emergence and transformation of “Pacific worlds” during the late 18th and early 19th centuries.
It explores how the environment, commerce, and culture linked what would become American Far West to the eastern Pacific Basin and also to other parts of the Americas.
The book shows that the American far west was an integral part of the developing Pacific world long before it became a nexus of national expansion.
