About this listen

A Financial Times Best Science Book of 2023

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 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.

Critic reviews

Riveting.... The cultural history fascinates.... Wide-ranging and meticulously detailed, this captures the wonder, beauty, and intrigue of its subject.—Publishers Weekly, starred review

The Blue Machine is a point of departure, a map for further exploration. Not since reading The Diversity of Life by E.O. Wilson have I read a book as timely, salient, and informative.—Todd L. Capson, Science

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

This book was pleasant to listen too. But There are some things that are contrived on climate change.

Great first 85%
But I don’t appreciate the constant (humans suck) view of society being jammed down my throat in every facility possible.

The correlation of the earth retaining more heat due to human pollution is argumentative at best, especially when you have things in scale. At one point in she’s quoted some man who apparently whitenesses climate change. I assume the man was a few hundred years old and still running sail boats in Hawaii. Climate fluctuations are measured in hundreds of years, not 40 or so.
CO2 is one of the lowest heat retaining gasses on the planet that’s in abundance in our atmosphere. It’s important for plants, without it they die. Like we would without oxygen. The global warming number scale provides a relative number for warming characteristics of different gasses. Methane is a 34 GWP. Freon R22 was 1810 GWP. R404a has a GWP of 3920. Co2 (R744) has GWP of 1. Which means methane retains 34x more than CO2. The scale is based on CO2 because it’s next to zero. But in the book she kips over what the additional heat from Co2 increase of 100 parts per million over 30 years amounts are, or what percentage of the temp fluctuations we’ve seen over 70 years of weather the 100ppm increase is responsible for, given the seriously low heat retention and amount of increase.

These facts negate the last 2 chapters of the book. There’s more on that topic That’s not going to be written here.
The author narrated I believe, she was pleasant, I appreciate the ocean information and some of the stories. But I’m disappointed in the fact that she’s a scientist and misunderstood climate, heat, and gases. She also can’t delineate between climate and weather patterns.

Amazing writing and storytelling

I listen to this book while working offshore and in full presence of “The Blue Machine”. Thus it felt more present and real, and I found myself appreciating more and more of it as the book delved deeper into its inner workings.

The author’s passion definitely comes through and she interweaves stories about history, culture and biology into the science of oceans so well that it seeps in and you find yourself falling in love with the main character, the oceans.

So it came as heartbreak (although it should have been obvious) in last chapter, when she drew a line from the actions of our recent past through the inactions of the present to project into the perils of the future that threatens all life on this Blue Marble of ours.

Brilliant and needed

This book is brilliantly written and somehow quilted complex information into insightful digestable peaces. it's so good, that I have started to read it again!

Very informative and transformational

Little details, simple language, interesting facts and full of worth understanding data. I’ll read this book again to keep learning.

Phenomenal book, highly overlooked

I am typically more interested in physics and cosmology, but I heard a podcast between the author and Sean Carroll and my interest was peaked. Listening to this book, I never knew the ocean was so extremely interesting and entertaining. I think the name of this book is a bit underwhelming and undersells the contents, but I highly recommend giving it a listen. From how we can trace the history of whale stress levels back over 150 years using their ear wax to how the different layers of the ocean interact (or don’t), this book is both informative and fun.

A mechanical universe?

Very informative. I learned a lot, but the insistent metaphor of the ocean as a machine or as an engine is quaintly archaic and significantly annoying. How much more fruitful it might have been to underscore the oceans of the world as a dynamic living system. So many scholars and writers in the fields of biology and earth-sciences seem to be tethered at the hip to the outdated and not always useful notion of a mechanical universe, a mechanical world. In the end it is self-defeating as a means towards embodied understanding. Otherwise the book was hugely informative in many other respects. Thank you!

Wonderful ocean explanation

A truly inspiring, educational, and even sometimes funny book about how the ocean works. A great view on oceanography as a whole to better understand the engine that is the ocean.

Wonderful knowledge locked into much detail

I very much enjoyed the book. I think this was presented fairly. ALL people on the planet need to understand is information. We area here in this form because of the ocean. So we must learn more about its working or suffer the consequences.
I think more use of footnotes in this book could greatly improve the spreading of this knowledge; as the knowledge is locked too deeply in the details for the average person to persevere through.
