FINANCIAL TIMES 2023 HIGHLIGHT

All of the Earth's ocean, from the equator to the poles, is a single engine powered by sunlight - a blue machine.

In a book that will recalibrate our view of this defining feature of our planet, physicist Helen Czerski dives deep to illuminate the murky depths of the ocean engine, examining the messengers, passengers and voyagers that live in it, travel over it, and survive because of it. From the ancient Polynesians who navigated the Pacific by reading the waves to permanent residents of the deep such as the Greenland shark that can live for hundreds of years, she explains the vast currents, invisible ocean walls and underwater waterfalls that all have their place in the ocean's complex, interlinked system.

Timely, elegant and passionately argued, The Blue Machine is one of the biggest stories ever told. The understanding it offers is crucial to our future. Drawing on years of experience at the forefront of marine science, Helen Czerski captures the magnitude and subtlety of this complex force, showing us the thrilling extent to which we are at the mercy of this great engine.

Critics Review

  • A spectacular read.

    Independent

  • [Czerski’s] profound, sparkling global ocean voyage mingles history and culture, natural history, geography, animals and people.

    Nature

  • ‘Czerski aims to greatly expand and even revolutionise the reader’s understanding of what is going on in seven tenths of the planet that is not covered in land

    Financial Times

  • Lively and engrossing … Alongside her vivid portrayal of waters sliding over one another, colliding, mixing andturning into ice or water vapour, she explains how the living beings within the sea alsoform part of the ‘blue machine’ … [Cerzski’s personal experience of both Polynesian canoes off Hawaii and ice floes near the North Pole is not icing on the cake but part of the argument of this excellent and important book.

    The Spectator

  • Helen Czerski’s fascinating new book casts the ocean as an extraordinary giant engine, and helps us grasp its complex physicsand its key role in climate change
