Blue Machine: How the Ocean Shapes Our World

Product Information

For more details, please consult the latest information provided by Royal Mail's International Incident Bulletin. Helen regularly presents BBC programmes on physics, the ocean and the atmosphere – recent series include Colour: The Spectrum of Science, Orbit, Operation Iceberg, Super Senses, Dara O’Briain’s Science Club, as well as programmes on bubbles, the sun and our weather. Drawing on years of experience at the forefront of marine science, Helen Czerski captures the magnitude and subtlety of Earth’s defining feature, showing us the thrilling extent to which we are at the mercy of this great engine. Aborda os tópicos com precisão mas numa contexto mais amplo, agradável de ler, com relato de experiências próprias de viagens, de modo a agradar mesmo uma clientela não especializada, sendo até mais direcionada para não especialistas que porém deverão apreciar esse modo de apresentação e mesmo aprender uma e outra coisa que provavelmente desconheciam.

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. Hotjar sets this cookie to know whether a user is included in the data sampling defined by the site's pageview limit.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. Part 2 is "Travelling the Blue Machine" This looks at life in the oceans and on the oceans and has 3 sections covering, messengers, passengers and voyagers. There seems to be no overall theme so the reader will probably come away remembering only some of the information. The concluding chapter warns about global warming - no doubt the book would not have got past the green girls in the publishing house if it didn't - but in the main body of the book CO2 gets only a couple of paragraphs.

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. Gaia Vince, science journalist, broadcaster and author of Nomad Century All of the Earth's ocean, from the equator to the poles, is a single engine powered by sunlight - a blue machine.As a physicist she studies the bubbles underneath breaking waves in the open ocean to understand their effects on weather and climate.

Drawing on years of experience at the forefront of marine science, Helen Czerski captures the magnitude and subtlety of Earth's defining feature, showing us the thrilling extent to which we are at the mercy of this great engine. I don’t remember when I have read a book that has been such a delight to read from start to finish, but that also, when I have come to the end, had totally altered my appreciation of the workings of our whole planet. The author includes huge amounts of information from the way the ocean moves, to the different depths and strata, she mentions how people have learnt to navigate and how humans have impacted it. 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.Reading this book has made me realise just how much the oceans do to keep our planet at the right temperature for life to exist and function. Wide-ranging and meticulously detailed, this captures the wonder, beauty, and intrigue of its subject. By understanding how the ocean works, and its essential role in our global system, we can learn how to protect our blue machine. Alongside her vivid portrayal of waters sliding over one another, colliding, mixing and turning into ice or water vapour, she explains how the living beings within the sea also form part of the ‘blue machine’. I was intrigued to learn that the faeces of blue whales, which are rich in iron and also float, contribute to marine growth.
