A scientist’s exploration of the "ocean engine"—the physics behind the ocean’s systems—and why it matters.

All of Earth’s oceans, from the equator to the poles, are a single engine powered by sunlight, driving huge flows of energy, water, life, and raw materials. In The Blue Machine, physicist and oceanographer Helen Czerski illustrates the mechanisms behind this defining feature of our planet, voyaging from the depths of the ocean floor to tropical coral reefs, estuaries that feed into shallow coastal seas, and Arctic ice floes.

Through stories of history, culture, and animals, she explains how water temperature, salinity, gravity, and the movement of Earth’s tectonic plates all interact in a complex dance, supporting life at the smallest scale—plankton—and the largest—giant sea turtles, whales, humankind. 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 …

A scientist’s exploration of the "ocean engine"—the physics behind the ocean’s systems—and why it matters.

In The Blue Machine, physicist and oceanographer Helen Czerski illustrates the mechanisms behind this defining feature of our planet, voyaging from the depths of the ocean floor to tropical coral reefs, estuaries that feed into shallow coastal seas, and Arctic ice floes.

Through stories of history, culture, and animals, she explains how water temperature, salinity, gravity, and the movement of Earth’s tectonic plates all interact in a complex dance, supporting life at the smallest scale—plankton—and the largest—giant sea turtles, whales, humankind. 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 introduces the messengers, passengers, and voyagers that rely on interlinked systems of vast currents, invisible ocean walls, and underwater waterfalls.

Most important, however, Czerski reveals that while the ocean engine has sustained us for thousands of years, today it is faced with urgent threats. By understanding how the ocean works, and its essential role in our global system, we can learn how to protect our blue machine. Timely, elegant, and passionately argued, The Blue Machine presents a fresh perspective on what it means to be a citizen of an ocean planet.

On the surface, this book seems like it would unlock a fascinating perspective on the oceans of the world. It is pitched from the first chapter as considering how the ocean is the largest machine on earth, a perspective I thought fascinating and also one that matches with a lot of social theory. Yet as the writing unravels, the machinic element seems to go out the window, replaced with quite disconnected anecdotes of the ocean that draw from history, geology and personal experience.

It is worth mentioning that I think Helen Czerski is probably an excellent scientist, and a thoughtful one too. But the writing was put down as if narrating a BBC television programme (which is her day-job). The paragraphs are full of intrigue that is missing the visual information to make it coherent, leading you into a paragraph with hints and clues only to reveal several pages later …

The paragraphs are full of intrigue that is missing the visual information to make it coherent, leading you into a paragraph with hints and clues only to reveal several pages later what the writing is about. This does not suit the medium of print at all. Also, the chapters are far too long and often meander wildly into different themes from where they start out. And if you are familiar with postcolonial theory there are quite a few clangers, such as sections where non-western historical scientists are described first by their features rather than their achievements (a Chinese eunuch stands out in my memory) while western scientists are introduced to sections where they have no role to play (captain Cook is mentioned at the beginning of a section about Hawai'i referencing geological activity thousands of years before he landed there, and is then never referenced again in the whole chapter – did he need to be mentioned at all?!). While some sections were interesting, they were mostly scientific history that were quite matter-of-fact, such as how the currents work or how discoveries had been made. In the end, I just found this a frustrating slog, and wished it had been what it had promised.
