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.
