The Blue Machine
Helen Czerski’s book ‘The Blue Machine’: How the Ocean Works is an engrossing look at the waters of our world. Oceanographer and physicist Czerski explores the systems that power Earth’s seas, from the ocean floor’s depths to tropical coral reefs, estuaries, and Arctic ice floes. She illustrates how water temperature, salinity, gravity, and the movement of Earth’s tectonic plates interact in a complicated dance with tales from history, culture, and wildlife.
Both the biggest scale of life (whales, gigantic sea turtles, and humans) and the tiniest size (plankton) are supported by this complex interaction. Crucially, Czerski draws attention to the immediate dangers to our ocean engine and underscores the necessity of safeguarding this essential system.
