“The nineteenth-century Challenger expedition was a voyage with a single purpose—scientific discovery. Macdougall looks forward rather than back and connects the Challenger findings with modern oceanographic and even lunar explorations. The result is truly a delight to read.”—Brian Skinner, Yale University“An epic Victorian-age expedition made relevant to the world today by Macdougall’s masterful prose. The excitement of discovery is infectiously brought to life in this delightful read. A landmark book about a landmark voyage.”—Nick Fraser, National Museums Scotland“Macdougall’s book not only brings to light a fascinating scientific expedition but also draws attention to the importance of scientific exploration and discovery even in today’s modern world.”—S. E. Brazer, Salisbury University
